Description

本発明は、基板の検査に使用される検査治具に関する。 The present invention relates to an inspection jig used to inspect substrates.

従来、テーブル上に載置された回路基板の表面側の配線パターンと裏面側の配線パターンとの間の導通検査を行う基板検査装置がある。このような基板検査装置において、基台の上方に上下動可能に設けられて、回路基板の導通検査を行うための検査治具が上面に取り付けられる昇降プレートと、上下方向に延在するねじ部と、このねじ部に螺合するナット部とからなり、昇降プレートを上下動させる複数本の送りねじ部材とを備えたものが知られている(例えば、特許文献1参照)。この基板検査装置は、送りねじ部材のねじ部およびナット部のいずれか一方を回転させて昇降プレートを上下動させることにより、回路基板の検査対象部(配線パターン)に検査用のプローブを接触させるように構成されている。 Conventionally, there is a circuit board inspection device that performs a continuity test between the wiring pattern on the front side and the wiring pattern on the back side of a circuit board placed on a table. Among such circuit board inspection devices, there is known one that is provided with a lift plate that is vertically movable above a base and has an inspection jig attached to its upper surface for performing a continuity test of the circuit board, and a plurality of feed screw members that are made up of a screw portion extending in the vertical direction and a nut portion that screws into the screw portion and moves the lift plate up and down (see, for example, Patent Document 1). This circuit board inspection device is configured to bring an inspection probe into contact with the part to be inspected (wiring pattern) of the circuit board by moving the lift plate up and down by rotating either the screw portion or the nut portion of the feed screw member.

また、基板(プリント配線基板)の検査に使用する中継用コネクタのコンタクト部に、異方性導電ゴム等からなる導電コネクタ材を設けることが行われている(例えば、特許文献2参照)。この中継コネクタは、基板の検査対象部に導電コネクタ材を接触させて加圧する等により、電気的な導通が得られるように構成されている。 In addition, a conductive connector material made of anisotropic conductive rubber or the like is provided in the contact portion of a relay connector used to inspect a substrate (printed wiring board) (see, for example, Patent Document 2). This relay connector is configured so that electrical continuity can be achieved by contacting the conductive connector material with the portion of the substrate to be inspected and applying pressure, etc.

上述の特許文献1に開示された基板検査装置によれば、送りねじ部材を高速で回転させる等により、所定の重量を有する検査治具及び昇降プレートを迅速に検査位置へ移動させることが可能である。この反面、前記ねじ送り部材有する昇降駆動機構では、その駆動力が大きいので微妙な位置の調節及び圧接力の設定が困難である。したがって、検査治具に設けられた検査用のコネクタ材が、基板の検査対象部に対して強固に圧接されることにより、検査用のプローブ又は検査対象部が損傷したり、逆に検査対象部に対するコネクタ材の圧接が不足することに起因した検査不良が生じたりし易い等の問題がある。 The circuit board inspection device disclosed in the above-mentioned Patent Document 1 makes it possible to quickly move an inspection jig and lift plate having a predetermined weight to an inspection position by rotating a feed screw member at high speed, etc. On the other hand, the lift drive mechanism having the above-mentioned screw feed member has a large driving force, making it difficult to finely adjust the position and set the pressure contact force. Therefore, there are problems such as the inspection connector material provided on the inspection jig being firmly pressed against the inspection target part of the circuit board, which can damage the inspection probe or the inspection target part, or conversely, inspection defects can easily occur due to insufficient pressure contact of the connector material against the inspection target part.

一方、上述の特許文献2に開示されているように異方性導電ゴム製の導電コネクタ材を、検査対象部に対応したコンタクト部に設けた構造によれば、柔軟な異方性導電ゴムが基板の検査対象部に面接触するため、細かな電極に対して高い接触安定性が得られる。しかし、前記導電コネクタ材を用いた検査装置では、基板の検査対象部に対する接触圧が少しでも高くなると、導電コネクタ材が損傷し易いという問題がある。しかも、前記導電コネクタ材の板厚方向以外に電流が流れることに起因する誤検出が発生し易い等の問題があった。 On the other hand, as disclosed in the above-mentioned Patent Document 2, a structure in which a conductive connector material made of anisotropic conductive rubber is provided in a contact portion corresponding to the part to be inspected allows the flexible anisotropic conductive rubber to come into surface contact with the part to be inspected on the board, providing high contact stability with fine electrodes. However, in an inspection device using the conductive connector material, there is a problem that the conductive connector material is easily damaged if the contact pressure on the part to be inspected on the board increases even slightly. In addition, there is a problem that erroneous detection is likely to occur due to current flowing in a direction other than the thickness direction of the conductive connector material.

本発明の目的は、基板の検査対象部及び検査治具のコンタクト部の損傷を抑制することが容易な検査治具を提供することである。 The object of the present invention is to provide an inspection jig that can easily prevent damage to the inspection target portion of the board and the contact portion of the inspection jig.

本発明の一例に係る検査治具は、検査対象の基板の検査対象部に接触するコンタクト部を有する可動板と、当該可動板を支持する支持部材とを備え、前記支持部材には、前記可動板を揺動可能に支持する支持軸を備えた枢支部と、前記支持軸を支点に前記可動板を揺動変位させて前記コンタクト部を前記検査対象部に接触させる揺動駆動部とが設けられたものである。 An inspection jig according to one example of the present invention comprises a movable plate having a contact portion that contacts an inspection target portion of a substrate to be inspected, and a support member that supports the movable plate, the support member being provided with a pivot portion having a support shaft that supports the movable plate so that it can swing, and a swing drive portion that swings and displaces the movable plate around the support shaft as a fulcrum, thereby bringing the contact portion into contact with the inspection target portion.

基板検査装置1は、図1に示すように、基板10を保持する基板保持部材2と、基板10の下方側に配設された第一検査治具4aと、基板10の上方側に配設された第二検査治具4bと、下方の第一検査治具4aを昇降変位させる第一昇降駆動機構5aと、上方の第二検査治具4bを昇降変位させる第二昇降駆動機構5bとを備えている。 As shown in FIG. 1, the substrate inspection device 1 includes a substrate holding member 2 that holds a substrate 10, a first inspection jig 4a disposed below the substrate 10, a second inspection jig 4b disposed above the substrate 10, a first lifting and lowering mechanism 5a that raises and lowers the lower first inspection jig 4a, and a second lifting and lowering mechanism 5b that raises and lowers the upper second inspection jig 4b.

検査対象の基板10は、例えばプリント配線基板、ガラスエポキシ基板、フレキシブル基板、セラミック多層配線基板、半導体パッケージ用のパッケージ基板、インターポーザ基板、フィルムキャリア等の基板であってもよく、液晶ディスプレイ、EL(Electro-Luminescence)ディスプレイ、タッチパネルディスプレイ等のディスプレイ用の電極板や、タッチパネル用等の電極板であってもよく、半導体ウェハ、半導体チップ、CSP(Chip size package)等の半導体基板であってもよく、種々の基板であってよい。 The substrate 10 to be inspected may be, for example, a printed wiring board, a glass epoxy substrate, a flexible substrate, a ceramic multilayer wiring substrate, a package substrate for a semiconductor package, an interposer substrate, a film carrier, or the like; it may be an electrode plate for a display such as a liquid crystal display, an EL (Electro-Luminescence) display, or a touch panel display, or an electrode plate for a touch panel, or it may be a semiconductor substrate such as a semiconductor wafer, a semiconductor chip, or a CSP (Chip size package), or it may be any of a variety of substrates.

当実施形態における基板10は、基板保持部材2上に保持される基板本体11と、基板保持部材2の側方に突出した状態で設置される側端部12とを有している。この側端部12の上面には、図2及び図3に示すように、配線パターン等からなる検査対象部13U,13Uが、所定間隔おいて左右に分離された状態で配設される。また、相隣接する検査対象部13U,13Uの間には、検査対象部が存在しない平坦面部14Uが形成されている。 The substrate 10 in this embodiment has a substrate body 11 held on the substrate holding member 2, and a side end portion 12 that is installed in a state where it protrudes to the side of the substrate holding member 2. As shown in Figures 2 and 3, inspection target portions 13U, 13U consisting of wiring patterns or the like are arranged on the upper surface of this side end portion 12, separated to the left and right at a predetermined interval. In addition, a flat surface portion 14U where no inspection target portion exists is formed between adjacent inspection target portions 13U, 13U.

一方、側端部12の下面には、配線パターン等からなる検査対象部13D,13Dが所定間隔おいて左右に分離された状態で配設されるとともに、相隣接する検査対象部13D,13Dの間には、検査対象部が存在しない平坦面部14Dが形成されている。各検査対象部13Dには、例えば互いに略平行に配置された複数の電極端子が、配線パターンによって形成されている。この各電極端子が、それぞれ検査対象の検査点とされている。 Meanwhile, on the underside of the side end portion 12, inspection target portions 13D, 13D consisting of wiring patterns or the like are arranged separated to the left and right at a predetermined interval, and between adjacent inspection target portions 13D, 13D, a flat surface portion 14D where no inspection target portion exists is formed. On each inspection target portion 13D, for example, a plurality of electrode terminals arranged approximately parallel to each other are formed by wiring patterns. Each of these electrode terminals is regarded as an inspection point of the inspection target.

また、基板10の上面に設けられた検査対象部13U,13Uと、基板10の下面に設けられた検査対象部13D,13Dとは、図3の左右方向に互いに変位した状態で配設されている。これにより、基板上面の検査対象部13Uと基板下面の平坦面部14Dとが上下に相対向して配設されるとともに、基板下面の検査対象部13Dと基板上面の平坦面部14Uとが上下に相対向して配設されている。各検査対象部13Uには、検査対象部13と同様の複数の電極端子が検査点として形成されている。 In addition, the inspection target portions 13U, 13U provided on the upper surface of the substrate 10 and the inspection target portions 13D, 13D provided on the lower surface of the substrate 10 are arranged in a state where they are displaced from each other in the left-right direction in FIG. 3. As a result, the inspection target portion 13U on the upper surface of the substrate and the flat surface portion 14D on the lower surface of the substrate are arranged facing each other vertically, and the inspection target portion 13D on the lower surface of the substrate and the flat surface portion 14U on the upper surface of the substrate are arranged facing each other vertically. Each inspection target portion 13U has a plurality of electrode terminals formed as inspection points, similar to those of the inspection target portion 13.

第一昇降駆動機構5aは、図1に示すように、サーボモータ等からなる回転駆動部51と、この回転駆動部51により回転駆動されるねじ軸52と、このねじ軸52の先端部(上端部)に設けられた昇降板53とを有するねじ送り機構からなっている。この昇降板53の上面には、第一検査治具4aが取り付けられている。 As shown in FIG. 1, the first lifting drive mechanism 5a is a screw feed mechanism having a rotation drive unit 51 made of a servo motor or the like, a screw shaft 52 that is rotated by the rotation drive unit 51, and a lifting plate 53 provided at the tip (upper end) of the screw shaft 52. The first inspection jig 4a is attached to the upper surface of the lifting plate 53.

第二昇降駆動機構5bは、第一昇降駆動機構5aと同様に、サーボモータ等からなる回転駆動部51と、この回転駆動部51により回転駆動されるねじ軸52とを有するねじ送り機構からなっている。このねじ軸52の先端部(下端部)には、上下一対の昇降板53a,53bが設けられるとともに、下方の昇降板53bの下面に、第二検査治具4bが取り付けられている。 The second lifting drive mechanism 5b, like the first lifting drive mechanism 5a, is composed of a screw feed mechanism having a rotation drive unit 51 consisting of a servo motor or the like, and a screw shaft 52 that is rotated by the rotation drive unit 51. A pair of upper and lower lifting plates 53a, 53b are provided at the tip (lower end) of the screw shaft 52, and a second inspection jig 4b is attached to the underside of the lower lifting plate 53b.

そして、基板10の検査を行う際に、第一昇降駆動機構5aの回転駆動部51を作動させてねじ軸52を回転駆動することにより、昇降板53及び第一検査治具4aを、下方の初期位置(図3参照)から、上方の検査待機位置、つまり図4に示すように、基板10の下面に設けられた検査対象部13D,13Dに、後述する第一検査治具4aにおけるコンタクト部63,63の導電コネクタ材の表面が近接した位置に上昇させるように構成されている。 When inspecting the substrate 10, the rotation drive unit 51 of the first lift drive mechanism 5a is operated to rotate the screw shaft 52, thereby lifting the lift plate 53 and the first inspection jig 4a from a lower initial position (see FIG. 3) to an upper inspection waiting position, that is, as shown in FIG. 4, to a position where the surfaces of the conductive connector material of the contact portions 63, 63 in the first inspection jig 4a described below are close to the inspection target portions 13D, 13D provided on the underside of the substrate 10.

また、第二昇降駆動機構5bの回転駆動部51を作動させてねじ軸52を回転駆動することにより、昇降板53a,53b及び第二検査治具4bを、上方の初期位置(図3参照)から、下方の検査待機位置、つまり図4に示すように、基板10の上面に設けられた検査対象部13U,13Uに、後述の第二検査治具4bにおけるコンタクト部63,63の導電コネクタ材の表面が近接した位置に下降させるように構成されている。 In addition, by operating the rotation drive unit 51 of the second lifting drive mechanism 5b to rotate the screw shaft 52, the lifting plates 53a, 53b and the second inspection jig 4b are lowered from the upper initial position (see FIG. 3) to a lower inspection waiting position, that is, as shown in FIG. 4, to a position where the surfaces of the conductive connector material of the contact portions 63, 63 in the second inspection jig 4b described below are close to the inspection target portions 13U, 13U provided on the upper surface of the substrate 10.

検査待機位置は、検査対象部13D,13Dと第一検査治具4aにおけるコンタクト部63,63の導電コネクタ材の表面との距離、及び検査対象部13U,13Uと第二検査治具4bにおけるコンタクト部63,63の導電コネクタ材の表面との距離が、例えば0.1mm~10.0mm程度となる位置とされている。 The inspection waiting position is a position where the distance between the inspection target parts 13D, 13D and the surface of the conductive connector material of the contact parts 63, 63 in the first inspection jig 4a, and the distance between the inspection target parts 13U, 13U and the surface of the conductive connector material of the contact parts 63, 63 in the second inspection jig 4b is, for example, about 0.1 mm to 10.0 mm.

第二昇降駆動機構5bには、第二検査治具4bを前記検査待機位置からさらに下降させるように駆動する左右一対の駆動シリンダからなる緩衝駆動部54,54が、昇降板53a,53bの間に設けられている。また、緩衝駆動部54,54の間には、昇降板53b及び第二検査治具4bをその自重に抗して上方に付勢する引張りばねからなる左右一対の付勢部材55,55が配設されている。 The second lifting drive mechanism 5b has a buffer drive section 54, 54 consisting of a pair of left and right drive cylinders that drive the second inspection jig 4b to further descend from the inspection waiting position, provided between the lifting plates 53a, 53b. In addition, a pair of left and right biasing members 55, 55 consisting of tension springs that bias the lifting plate 53b and the second inspection jig 4b upward against their own weight are provided between the buffer drive sections 54, 54.

緩衝駆動部54は、その駆動部に供給される一定圧の駆動エアに応じて第二検査治具4bを下降させることにより、必要に応じて基板10の検査対象部13U,13Uに第二検査治具4bのコンタクト部63,63を当接させる。緩衝駆動部54としては、例えば、例えばSMC(株)製MQQTシリーズのエアシリンダ等の、低摩擦エアシリンダを用いることができる。 The buffer drive unit 54 lowers the second inspection jig 4b in response to a constant pressure of driving air supplied to the drive unit, thereby bringing the contact portions 63, 63 of the second inspection jig 4b into contact with the inspection target portions 13U, 13U of the board 10 as necessary. As the buffer drive unit 54, for example, a low-friction air cylinder such as an MQQT series air cylinder manufactured by SMC Corporation can be used.

また、緩衝駆動部54,54を構成する前記エアシリンダは、低摩擦のため圧力制御が容易であり、検査対象部13U,13Uに対するコンタクト部63,63の圧接力を、精度よく制御することが容易である。 In addition, the air cylinder that constitutes the buffer drive unit 54, 54 has low friction, making it easy to control the pressure, and it is easy to precisely control the pressure contact force of the contact parts 63, 63 against the inspection target parts 13U, 13U.

図5は、基板保持部材の具体的構成を示す断面図、図6は、基板保持部材を分解した状態を示す斜視図、図7は、パッキンの他の例を示す斜視図、基板保持部材の変形例を示す分解断面図である。 Figure 5 is a cross-sectional view showing the specific configuration of the substrate holding member, Figure 6 is a perspective view showing the substrate holding member in an exploded state, and Figure 7 is a perspective view showing another example of a packing and an exploded cross-sectional view showing a modified example of the substrate holding member.

基板保持部材2は、図5及び図6に示すように、図示を省略した吸引装置の吸引力に応じて基板10を吸着する吸着孔20が形成された吸着板21と、吸着板21の吸着孔20から吸引された空気を吸引装置側に導出する連通孔22が形成された支持板23とを有している。また、吸着板21と中間板25との間には、パッキン24が配設されている。 As shown in Figures 5 and 6, the substrate holding member 2 has an adsorption plate 21 with suction holes 20 formed therein that adsorb the substrate 10 in response to the suction force of a suction device (not shown), and a support plate 23 with a communication hole 22 formed therein that guides the air sucked through the suction holes 20 of the adsorption plate 21 to the suction device side. In addition, a packing 24 is disposed between the adsorption plate 21 and the intermediate plate 25.

吸着板21は、多数の吸着孔20が一定間隔でマトリックス状に配列されたプレート材からなり、その上面に基板1
0の主要部に対応した大きさ、具体的には基板本体11を載置し得る大きさを有している。
The suction plate 21 is made of a plate material in which a large number of suction holes 20 are arranged in a matrix at regular intervals, and the substrate 1 is attached to the upper surface of the plate material.
0, specifically, has a size capable of mounting the substrate body 11 thereon.

支持板23は、吸着板21の吸着孔20に対応した多数の連通孔22が一定間隔でマトリックス状に配列された中間板25と、その裏面を覆う被覆板26とを有している。この被覆板26には、図外の吸引装置に連通する凹部27が形成されている。この凹部27内の空気と、吸着板21の吸着孔20及び中間板25の連通孔22内の空気とが、図5の矢印Qに示すように外部に排出されることにより、吸着板21の表面上に基板10を密着させる負圧が得られるようになっている。 The support plate 23 has an intermediate plate 25 in which numerous communication holes 22 corresponding to the suction holes 20 of the suction plate 21 are arranged in a matrix at regular intervals, and a cover plate 26 that covers the back surface of the intermediate plate 25. This cover plate 26 has a recess 27 formed therein that communicates with a suction device not shown. The air in this recess 27 and the air in the suction holes 20 of the suction plate 21 and the communication holes 22 of the intermediate plate 25 are exhausted to the outside as shown by the arrow Q in Figure 5, thereby generating a negative pressure that causes the substrate 10 to adhere tightly to the surface of the suction plate 21.

パッキン24には、基板10の吸着範囲に対応した大きさを有する開口部28と、開口部28の外周部を囲繞する囲繞部29とが設けられている。そして、吸着板21と中間板25との間にパッキン24を配設して、基板10の吸着範囲外に位置する吸着孔20と連通孔22との連通を遮断することにより、吸着板21の上面に基板10の主要部を強固に密着させる大きな吸引力を生じさせ得るように構成されている。 The packing 24 has an opening 28 whose size corresponds to the suction range of the substrate 10, and a surrounding portion 29 that surrounds the outer periphery of the opening 28. The packing 24 is disposed between the suction plate 21 and the intermediate plate 25, blocking communication between the suction holes 20 located outside the suction range of the substrate 10 and the communication holes 22, thereby generating a large suction force that firmly adheres the main portion of the substrate 10 to the upper surface of the suction plate 21.

なお、図7に示すように、大きさの異なる開口部28a,28bを有する複数枚のパッキン24a,24bを予め取り揃えた構成とすることが好ましい。そして、基板10の種類に対応した開口部28を有するものをユーザが選択して吸着板21と中間板25との間に配設することにより、基板10の大きさに応じて負圧の生成範囲を変化させることができる。 As shown in FIG. 7, it is preferable to have a configuration in which multiple packings 24a, 24b with openings 28a, 28b of different sizes are prepared in advance. The user can then select a packing with an opening 28 that corresponds to the type of substrate 10 and place it between the suction plate 21 and the intermediate plate 25, thereby changing the range in which negative pressure is generated depending on the size of the substrate 10.

また、図8に示すように、吸着板21の下面に、パッキン24の板厚に対応した突出量を有する複数個の突部30が一定間隔で設けられるとともに、パッキン24の囲繞部29に突部30に設置部に対応する位置に、突部30が嵌入される嵌入孔31が設けられた構成としてもよい。 Also, as shown in FIG. 8, a configuration may be adopted in which a plurality of protrusions 30 having a protrusion amount corresponding to the plate thickness of the packing 24 are provided at regular intervals on the underside of the suction plate 21, and fitting holes 31 into which the protrusions 30 are fitted are provided at positions corresponding to the installation portions of the surrounding portion 29 of the packing 24.

この構成によれば、吸着板21と中間板25との間にパッキン24を配設する際に、突部30をパッキン24の嵌入孔31に嵌入することにより、パッキン24とを正確に位置合わせすることができる。また、吸着板21と中間板25との間に突部30が介在されることにより、吸着板21と中間板25との間隔を一定に保持することが可能となる。このため、吸着板21が変形し易い素材により形成されている場合であっても、前記負圧等に応じて吸着板21が変形するのを抑制することができ、基板10と吸着板21との間に隙間が形成されるのを防止できるという利点がある。 With this configuration, when the packing 24 is disposed between the suction plate 21 and the intermediate plate 25, the protrusion 30 can be fitted into the insertion hole 31 of the packing 24, thereby allowing the packing 24 to be accurately aligned. In addition, by interposing the protrusion 30 between the suction plate 21 and the intermediate plate 25, it is possible to maintain a constant distance between the suction plate 21 and the intermediate plate 25. Therefore, even if the suction plate 21 is made of a material that is easily deformed, it is possible to suppress deformation of the suction plate 21 in response to the negative pressure, etc., and there is an advantage in that it is possible to prevent a gap from being formed between the substrate 10 and the suction plate 21.

図9は、第一検査治具の概略構成を示す平面図、図10は、支持ブロックの概略構成を示す斜視図、図11は、第一検査治具の具体的構成を示す断面図、図12は、第一検査治具の具体的構成を示す図11のXII-XII線断面図である。 Figure 9 is a plan view showing the general configuration of the first inspection jig, Figure 10 is a perspective view showing the general configuration of the support block, Figure 11 is a cross-sectional view showing the specific configuration of the first inspection jig, and Figure 12 is a cross-sectional view taken along line XII-XII in Figure 11 showing the specific configuration of the first inspection jig.

第一検査治具4a及び第二検査治具4bは、上下対称に配設されている点を除いて同一の構成を有するため、第一検査治具4aの構成のみを以下に説明し、第二検査治具4bの構成についてはその説明を省略する。 The first inspection jig 4a and the second inspection jig 4b have the same configuration except that they are arranged symmetrically from top to bottom, so only the configuration of the first inspection jig 4a will be explained below, and the explanation of the configuration of the second inspection jig 4b will be omitted.

第一検査治具4aは、基板10の下方側に配設された第一可動板6aと、この第一可動板6aを支持する支持部材7とを有している(図1参照)。第一可動板6aの一側辺部の上面には、図9及び図10に示すように、導電ゴム製の導電コネクタ材が配設されたコンタクト部63,63が設けられている。第一可動板6aの一側辺部上面には、検査対象部13Dの複数の電極端子と対向するように、複数の検出電極が形成されている。そして、複数の検出電極を覆うように導電コネクタ材が配設されて、コンタクト部63が形成されている。 The first inspection jig 4a has a first movable plate 6a arranged below the substrate 10 and a support member 7 that supports the first movable plate 6a (see FIG. 1). As shown in FIGS. 9 and 10, the upper surface of one side of the first movable plate 6a is provided with contact portions 63, 63 on which a conductive connector material made of conductive rubber is arranged. A plurality of detection electrodes are formed on the upper surface of one side of the first movable plate 6a so as to face a plurality of electrode terminals of the inspection target portion 13D. A conductive connector material is arranged to cover the plurality of detection electrodes, forming the contact portion 63.

コンタクト部63,63に配設される導電コネクタ材としては、加圧時に導通状態となる異方導電性ゴム、例えば株式会社JMT製「加圧導電ゴムPCR(登録商標)」が好適に使用される。なお、上述の加圧導電ゴムに代え、圧力を加えなくとも検査対象部を接触させるだけで板厚方向に導通状態となる異方導電性ゴムを用いてもよい。 As the conductive connector material arranged in the contact parts 63, 63, anisotropic conductive rubber that becomes conductive when pressure is applied, such as "Pressurized Conductive Rubber PCR (registered trademark)" manufactured by JMT Corporation, is preferably used. Note that instead of the above-mentioned pressurized conductive rubber, anisotropic conductive rubber that becomes conductive in the plate thickness direction simply by contacting the part to be inspected without applying pressure may be used.

第一可動板6aは、図11に示すように、プリント配線基板等からなる可動板本体61と、その下面部を補強する補強板62とを有している。第一可動板6aの他側辺部には、コンタクト部63の各検出電極を、図示を省略したワイヤケーブル等を介して図外の検査装置本体と接続するためのコネクタ64が設けられている。また、補強板62の他側辺部には、第一可動板6aを揺動可能に支持する後述の枢支部8が設けられている。 As shown in FIG. 11, the first movable plate 6a has a movable plate body 61 made of a printed wiring board or the like, and a reinforcing plate 62 that reinforces its lower surface. A connector 64 is provided on the other side edge of the first movable plate 6a to connect each detection electrode of the contact portion 63 to an inspection device body (not shown) via a wire cable or the like (not shown). In addition, a pivot part 8 (described below) that supports the first movable plate 6a so that it can swing is provided on the other side edge of the reinforcing plate 62.

第一可動板6aのコンタクト部63,63は、図3に示すように、基板10の下面に設置された検査対象部13D,13Dに対向するように複数個所に分離された状態でそれぞれ設置されている。また、相隣接するコンタクト部63,63の設置個所の間には、枢支部8の設置部側、つまり第一可動板6aの他側辺部側に向けて凹入する切欠部65が形成されている(図9及び図10参照)。 As shown in FIG. 3, the contact parts 63, 63 of the first movable plate 6a are installed in a separated state in a plurality of locations so as to face the inspection target parts 13D, 13D installed on the underside of the substrate 10. In addition, a notch 65 is formed between the installation locations of adjacent contact parts 63, 63, which recesses toward the installation part side of the pivot part 8, i.e., toward the other side edge side of the first movable plate 6a (see FIG. 9 and FIG. 10).

支持部材7には、図1、図11及び図12に示すように、第一昇降駆動機構5aにより昇降駆動されるベースプレート71と、第一可動板6aの揺動支点となる支持軸81を備えた枢支部8と、支持軸81を支点に第一可動板6aを揺動変位させる揺動駆動部72と、基板10を支持する支持ブロック9とが設けられている。 As shown in Figures 1, 11 and 12, the support member 7 is provided with a base plate 71 that is driven to move up and down by the first lifting drive mechanism 5a, a pivot part 8 having a support shaft 81 that serves as the swing fulcrum of the first movable plate 6a, a swing drive part 72 that swings and displaces the first movable plate 6a around the support shaft 81, and a support block 9 that supports the substrate 10.

枢支部8は、ベースプレート71に立設された一対の支持プレート82,82と、この支持プレート82,82に両端部が固定された支持軸81と、第一可動板6aの補強板62に固定された軸受部83とを有している。この軸受部83が支持軸81に外嵌されて回動可能に枢支されることにより、第一可動板6aが支持軸81を支点にして揺動可能に支持されている。 The pivot portion 8 has a pair of support plates 82, 82 erected on the base plate 71, a support shaft 81 with both ends fixed to the support plates 82, 82, and a bearing portion 83 fixed to the reinforcing plate 62 of the first movable plate 6a. The bearing portion 83 is fitted onto the support shaft 81 and pivotally supported so that the first movable plate 6a is supported so as to be able to swing about the support shaft 81.

揺動駆動部72は、第一可動板6aを、支持軸81を支点にして揺動変位させてコンタクト部63,63を基板10の検査対象部13D,13Dに一定圧力で接触させるように構成されている。揺動駆動部72としては、例えば緩衝駆動部54と同様、SMC(株)製MQQTシリーズのエアシリンダ等を用いることができる。 The swing drive unit 72 is configured to swing and displace the first movable plate 6a around the support shaft 81 as a fulcrum, so that the contact portions 63, 63 come into contact with the inspection target portions 13D, 13D of the substrate 10 at a constant pressure. As with the buffer drive unit 54, for example, an air cylinder of the MQQT series manufactured by SMC Corporation can be used as the swing drive unit 72.

ベースプレート71は、第一昇降駆動機構5aの昇降板53に固着された板材からなっている。このベースプレート71と第一可動板6aの補強板62との間には、第一可動板6aを下方に付勢する引張りばねからなる付勢部材73と、第一可動板6aの下面に当接してその下方変位を規制する支柱等からなる規制部材74とが設けられている。 The base plate 71 is made of a plate material fixed to the lift plate 53 of the first lift drive mechanism 5a. Between this base plate 71 and the reinforcing plate 62 of the first movable plate 6a, there are provided a biasing member 73 made of a tension spring that biases the first movable plate 6a downward, and a restricting member 74 made of a support or the like that abuts against the underside of the first movable plate 6a and restricts its downward displacement.

揺動駆動部72の非作動時には、付勢部材73により第一可動板6aが下方に付勢されて、その下面が規制部材74の上端面に当接した状態となる。これにより、第一可動板6aの下方変位が規制されて、第一可動板6aの設置状態が略水平に維持されるように構成されている。 When the swing drive unit 72 is not in operation, the first movable plate 6a is urged downward by the urging member 73, and its lower surface is in contact with the upper end surface of the regulating member 74. This regulates the downward displacement of the first movable plate 6a, and the first movable plate 6a is configured to be maintained in a substantially horizontal position.

支持ブロック9は、図3及び図10に示すように、取付ビス等によりベースプレート71の一側辺部上面に取り付けられる取付部91と、この取付部91に立設された複数本の突部92,92とを有している。突部92は、第一可動板6aに形成された切欠部65よりもやや小さい断面形状を有し、突部92の上端部が第一可動板6aの切欠部65内に導入されるようになっている(図9及び図10参照)。 As shown in Figures 3 and 10, the support block 9 has an attachment portion 91 that is attached to the upper surface of one side of the base plate 71 with mounting screws or the like, and multiple protrusions 92, 92 erected on the attachment portion 91. The protrusions 92 have a cross-sectional shape that is slightly smaller than the notch 65 formed in the first movable plate 6a, and the upper end of the protrusion 92 is adapted to be inserted into the notch 65 of the first movable plate 6a (see Figures 9 and 10).

そして、後述の導通検査時に、第二検査治具4bの第二可動板6bが揺動駆動部72により駆動されて、図4の矢印Pで示すように、第二可動板6bから基板10の上面に押圧力が付与されると、第一検査治具4aに設けられた支持ブロック9の突部92,92により基板10の下面が支持されることになる。 Then, during the continuity test described below, the second movable plate 6b of the second inspection jig 4b is driven by the swing drive unit 72, and as shown by the arrow P in FIG. 4, a pressing force is applied from the second movable plate 6b to the upper surface of the substrate 10, and the lower surface of the substrate 10 is supported by the protrusions 92, 92 of the support block 9 provided on the first inspection jig 4a.

この結果、基板10の下方変位が抑制され、前記押圧力に応じて第二可動板6bのコンタクト部63,63が適度に加圧されることにより導電コネクタ材がその厚み方向に導通する。その結果、検査対象部13U,13Uに形成された各電極端子と、第二可動板6bにおけるコンタクト部63,63の各検出電極とが導通状態となる。 As a result, downward displacement of the substrate 10 is suppressed, and the contact portions 63, 63 of the second movable plate 6b are appropriately pressurized in response to the pressing force, so that the conductive connector material is conductive in its thickness direction. As a result, each electrode terminal formed on the inspection target portions 13U, 13U and each detection electrode of the contact portions 63, 63 on the second movable plate 6b are in a conductive state.

また、同様にして、基板10の下方に配設された第一検査治具4aの第一可動板6aが揺動駆動部72によって駆動されることにより、第一可動板6aから基板10の下面に押圧力が付与されると、第二検査治具4bに設けられた支持ブロック9の突部92,92により基板10の上面が支持された状態で、第一可動板6aのコンタクト部63,63が適度に加圧されることにより導電コネクタ材がその厚み方向に導通する。その結果、検査対象部13D,13Dに形成された各電極端子と、第一可動板6aにおけるコンタクト部63,63の各検出電極とが導通状態となる。 In the same manner, when the first movable plate 6a of the first inspection jig 4a arranged below the substrate 10 is driven by the swing drive unit 72, a pressing force is applied from the first movable plate 6a to the lower surface of the substrate 10, and the upper surface of the substrate 10 is supported by the protrusions 92, 92 of the support block 9 provided on the second inspection jig 4b, the contact portions 63, 63 of the first movable plate 6a are appropriately pressurized, so that the conductive connector material is conductive in the thickness direction. As a result, each electrode terminal formed on the inspection target portions 13D, 13D and each detection electrode of the contact portions 63, 63 on the first movable plate 6a are in a conductive state.

上述の構成を有する基板検査装置1を使用して基板10の検査を行う場合には、基板10を基板保持部材2に支持させた状態で、第一昇降駆動機構5a及び第二昇降駆動機構5bの回転駆動部51を作動させて、ねじ軸52を回転駆動することにより、第一検査治具4a及び第二検査治具4bを、図4に示す検査待機位置にそれぞれ移動させる。 When inspecting the substrate 10 using the substrate inspection device 1 having the above-mentioned configuration, the substrate 10 is supported by the substrate holding member 2, and the rotation drive units 51 of the first lifting and lowering drive mechanism 5a and the second lifting and lowering drive mechanism 5b are operated to rotate the screw shaft 52, thereby moving the first inspection jig 4a and the second inspection jig 4b to the inspection waiting positions shown in FIG. 4.

次いで、第一検査治具4a及び第二検査治具4bの揺動駆動部72を作動させることにより、第一可動板6a及び第二可動板6bを、支持軸81を支点にそれぞれ揺動変位させる。これにより、第一可動板6aのコンタクト部63が基板下面の検査対象部13Dに所定の押圧力で圧接されるとともに、第二可動板6bのコンタクト部63が基板上面の検査対象部13Uに所定の押圧力で圧接されることになる。 Then, by operating the swing drive parts 72 of the first inspection jig 4a and the second inspection jig 4b, the first movable plate 6a and the second movable plate 6b are each swung and displaced about the support shaft 81 as a fulcrum. As a result, the contact part 63 of the first movable plate 6a is pressed against the inspection target part 13D on the underside of the board with a predetermined pressing force, and the contact part 63 of the second movable plate 6b is pressed against the inspection target part 13U on the upper surface of the board with a predetermined pressing force.

このようにコンタクト部63,63が適度に加圧された状態で、基板10の検査対象部13D,13Uに接触することにより、コンタクト部63,63の各検出電極と、検査対象部13D,13Uの各電極端子とが導通状態となる。そして、例えば第一検査治具4aのコンタクト部63から基板10の検査対象部13D,13Uの電極端子に測定用電流を供給するとともに、この測定用電流に応じて生じた電圧を、第二検査治具4bのコンタクト部63から導電コネクタ材を介して図外の検査装置本体に出力することにより、基板10の良否判定を実行することができる。 When the contact portions 63, 63 are appropriately pressurized in this manner, they come into contact with the inspection target portions 13D, 13U of the substrate 10, and the detection electrodes of the contact portions 63, 63 are brought into a conductive state with the electrode terminals of the inspection target portions 13D, 13U. Then, for example, a measurement current is supplied from the contact portion 63 of the first inspection jig 4a to the electrode terminals of the inspection target portions 13D, 13U of the substrate 10, and a voltage generated in response to this measurement current is output from the contact portion 63 of the second inspection jig 4b via a conductive connector material to the main inspection device body (not shown), thereby making it possible to determine whether the substrate 10 is good or bad.

なお、後述するように第二検査治具4bの揺動駆動部72の作動を必要に応じて停止し、第二可動板6bを水平に保持した状態で、第二昇降駆動機構5bの緩衝駆動部54を作動させて、第二検査治具4bを昇降駆動することにより、第二可動板6bのコンタクト部63を一定の圧力で基板10の検査対象部13Uに接触させることも可能である。 As described below, it is also possible to stop the operation of the swing drive unit 72 of the second inspection jig 4b as necessary, and while holding the second movable plate 6b horizontally, operate the buffer drive unit 54 of the second lifting drive mechanism 5b to lift and lower the second inspection jig 4b, thereby bringing the contact portion 63 of the second movable plate 6b into contact with the inspection target portion 13U of the substrate 10 with a constant pressure.

上述のように基板10を保持する基板保持部材2と、基板10の検査対象部13D,13Dに接触するコンタクト部63が設けられた第一可動板6a及びこれを支持する支持部材7を有する第一検査治具4aと、基板10の検査対象部13Uに接触するコンタクト部63が設けられた第二可動板6b及びこれを支持する支持部材7を有する第二検査治具4bと、第一検査治具4a及び第二検査治具4bを検査待機位置にそれぞれ移動させる第一昇降駆動機構5a及び第二昇降駆動機構5bとを備え、支持部材7には、第一可動板6a及び第二可動板6bを揺動可能に支持する支持軸81を備えた枢支部8と、支持軸81を支点に第一可動板6a及び第二可動板6bを揺動変位させてコンタクト部63,63を検査対象部13U,13Dにそれぞれ接触させる揺動駆動部72とが設けられた基板検査装置1によれば、検査対象部13U,13D及びコンタクト部63の損傷を抑制しつつ、基板10の検査を正確に行うことができる。 As described above, the substrate holding member 2 holds the substrate 10; the first inspection jig 4a has a first movable plate 6a provided with a contact portion 63 that contacts the inspection target portion 13D, 13D of the substrate 10 and a support member 7 that supports the first movable plate 6a; the second inspection jig 4b has a second movable plate 6b provided with a contact portion 63 that contacts the inspection target portion 13U of the substrate 10 and a support member 7 that supports the second movable plate 6b; and the first lifting and lowering drive mechanism 5a and the second inspection jig 4b that move the first inspection jig 4a and the second inspection jig 4b to the inspection waiting position, respectively. and a second lifting drive mechanism 5b, and the support member 7 is provided with a pivot part 8 having a support shaft 81 that supports the first movable plate 6a and the second movable plate 6b so that they can swing, and a swing drive part 72 that swings and displaces the first movable plate 6a and the second movable plate 6b about the support shaft 81 as a fulcrum to bring the contact parts 63, 63 into contact with the inspection target parts 13U, 13D, respectively. According to the substrate inspection device 1, it is possible to accurately inspect the substrate 10 while suppressing damage to the inspection target parts 13U, 13D and the contact parts 63.

すなわち、第一昇降駆動機構5a及び第二昇降駆動機構5bは、第一可動板6a及び第二可動板6bを基板10に近接させた検査待機位置に昇降変位させる機能を有するものであればよく、微妙な位置制御及び駆動力制御は不要である。このため、上述の実施形態に示すように、サーボモータ等からなる回転駆動部51と、この回転駆動部51により回転駆動されるねじ軸52と有し、大きな駆動力が得られるねじ送り機構からなる第一昇降駆動機構5a及び第二昇降駆動機構5bを用いることにより、所定の重量を有する第一検査治具4a及び第二検査治具4bを前記初期位置から検査待機位置に容易かつ迅速に移動させることができる。 In other words, the first lifting drive mechanism 5a and the second lifting drive mechanism 5b only need to have the function of lifting and displacing the first movable plate 6a and the second movable plate 6b to an inspection standby position close to the substrate 10, and delicate position control and drive force control are not required. Therefore, as shown in the above embodiment, by using the first lifting drive mechanism 5a and the second lifting drive mechanism 5b, which have a rotation drive unit 51 consisting of a servo motor or the like and a screw shaft 52 rotated and driven by this rotation drive unit 51 and are made up of a screw feed mechanism that can obtain a large driving force, the first inspection jig 4a and the second inspection jig 4b, which have a predetermined weight, can be easily and quickly moved from the initial position to the inspection standby position.

第一検査治具4a及び
第二検査治具4bを検査待機位置に移動させた状態で、揺動駆動部72により支持軸81を支点に第一可動板6a及び第二可動板6bを揺動変位させてコンタクト部63,63を検査対象部13U,13Dに接触させる際における駆動抵抗は、枢支部8の摺動抵抗だけである。このため、揺動駆動部72として低摩擦かつ高感度のエアシリンダを用いることにより、コンタクト部63,63を検査対象部13U,13Dに適度の圧力で正確に接触させて基板10を適正に検査することができる。
With the first inspection jig 4a and the second inspection jig 4b moved to the inspection standby position, the swing drive unit 72 swings and displaces the first movable plate 6a and the second movable plate 6b about the support shaft 81 as a fulcrum to bring the contact portions 63, 63 into contact with the inspection target portions 13U, 13D, and the drive resistance is only the sliding resistance of the pivot portion 8. For this reason, by using a low-friction, highly sensitive air cylinder as the swing drive unit 72, the contact portions 63, 63 can be accurately brought into contact with the inspection target portions 13U, 13D with an appropriate pressure, thereby enabling the board 10 to be properly inspected.

なお、サーボモータ等からなる回転駆動部51と、この回転駆動部51により回転駆動されるねじ軸52とを有する上述のねじ送り機構に代え、第一検査治具4a及び第二検査治具4bを初期位置から検査待機位置に容易かつ迅速に移動させることが可能な駆動力を有する油圧シリンダ又は大型のエアシリンダ等により第一昇降駆動機構5a及び第二昇降駆動機構5bを構成してもよい。 In addition, instead of the above-mentioned screw feed mechanism having a rotation drive unit 51 consisting of a servo motor or the like and a screw shaft 52 that is rotationally driven by this rotation drive unit 51, the first lifting drive mechanism 5a and the second lifting drive mechanism 5b may be configured using a hydraulic cylinder or a large air cylinder that has a driving force capable of easily and quickly moving the first inspection jig 4a and the second inspection jig 4b from the initial position to the inspection standby position.

また、上述のエアシリンダからなる揺動駆動部72に代え、支持軸81を支点に第一可動板6a及び第二可動板6bを揺動変位させるねじ軸と、このねじ軸を回転駆動する小型のサーボモータとを有するねじ送り機構等を用いることも可能である。 In addition, instead of the swing drive unit 72 consisting of the air cylinder described above, it is also possible to use a screw feed mechanism having a screw shaft that swings and displaces the first movable plate 6a and the second movable plate 6b around the support shaft 81 as a fulcrum, and a small servo motor that rotates and drives this screw shaft.

導電ゴム製の導電コネクタ材をコンタクト部63に配設してなる上述の実施形態に代え、適度の弾力性を有するワイヤプローブからなるプローブ方式の接触端子、又は導電体からなるプランジャーと、このプランジャーをスライド可能に支持する筒状体と、プランジャーの先端部を筒状体外に突出させる方向に付勢する付勢部材等とを有するプローブ方式の接触端子を、コンタクト部63に配設した構成としてもよい。 Instead of the above-described embodiment in which a conductive connector material made of conductive rubber is disposed in the contact portion 63, a probe-type contact terminal consisting of a wire probe having appropriate elasticity, or a probe-type contact terminal having a plunger made of a conductor, a cylindrical body that slidably supports the plunger, and a biasing member that biases the tip of the plunger in a direction that causes it to protrude outside the cylindrical body, may be disposed in the contact portion 63.

上述の実施形態に示すように、第一可動板6a及び第二可動板6bのコンタクト部63に柔軟な導電ゴム製の導電コネクタ材を配設した構造とした場合には、この導電コネクタ材を検査対象部13U,13Dに面接触させることにより、細かな電極に対して高い接触安定性が得られる等の利点がある。また、前記導電ゴム製の導電コネクタ材は、微細電極でも位置ずれに対して広い許容幅を有し、かつ基板10の検査対象部13U,13Dにダメージを与えることがないとともに、検査治具を軽量かつ薄型に形成できる等の利点がある。 As shown in the above embodiment, when a conductive connector material made of flexible conductive rubber is arranged on the contact portion 63 of the first movable plate 6a and the second movable plate 6b, this conductive connector material is brought into surface contact with the inspection target portions 13U and 13D, which has the advantage of providing high contact stability for fine electrodes. In addition, the conductive connector material made of conductive rubber has a wide tolerance for positional deviation even for fine electrodes, does not damage the inspection target portions 13U and 13D of the substrate 10, and has the advantage of allowing the inspection jig to be formed to be lightweight and thin.

なお、上述の導電ゴム製の導電コネクタ材を用いた検査装置では、導電コネクタ材が損傷し易い傾向がある。しかし、上述のように検査待機位置にある第一検査治具4a及び第二検査治具4bを揺動駆動部72により支持軸81を支点に揺動変位させるので、支持軸81で第一検査治具4a及び第二検査治具4bの重量を支えて、小さな力で第一検査治具4a及び第二検査治具4bを揺動変位させることができる。その結果、コンタクト部63,63を検査対象部13U,13Dに圧接する圧力の制御が容易となり、コンタクト部63,63の接触圧力を高精度に制御することができる。従って、導電コネクタ材の損傷を抑制することが容易となる。 In addition, in the inspection device using the conductive connector material made of conductive rubber described above, the conductive connector material tends to be easily damaged. However, as described above, the first inspection jig 4a and the second inspection jig 4b in the inspection waiting position are oscillated and displaced around the support shaft 81 by the swing drive unit 72, so that the weight of the first inspection jig 4a and the second inspection jig 4b can be supported by the support shaft 81 and the first inspection jig 4a and the second inspection jig 4b can be oscillated and displaced with a small force. As a result, it becomes easier to control the pressure with which the contact parts 63, 63 are pressed against the inspection target parts 13U, 13D, and the contact pressure of the contact parts 63, 63 can be controlled with high precision. Therefore, it becomes easier to suppress damage to the conductive connector material.

さらに、上述の実施形態では、基板10の下方側に配設された第一可動板6aを有する第一検査治具4aと、基板10の上方側に配設された第二可動板6bを有する第二検査治具4bと、第一検査治具4aを昇降駆動する第一昇降駆動機構5aと、第二検査治具4bを昇降駆動する第二昇降駆動機構5bとを備えた構成としたため、第一昇降駆動機構5a及び第二昇降駆動機構5bにより、第一可動板6a及び第二可動板6bを基板10に近接させた検査待機位置にそれぞれ迅速に移動させることができる。 Furthermore, in the above-described embodiment, the configuration includes a first inspection jig 4a having a first movable plate 6a arranged below the substrate 10, a second inspection jig 4b having a second movable plate 6b arranged above the substrate 10, a first lifting drive mechanism 5a that drives the first inspection jig 4a to move up and down, and a second lifting drive mechanism 5b that drives the second inspection jig 4b to move up and down. Therefore, the first lifting drive mechanism 5a and the second lifting drive mechanism 5b can quickly move the first movable plate 6a and the second movable plate 6b to an inspection waiting position close to the substrate 10, respectively.

しかも、第一検査治具4a及び第二検査治具4bの揺動駆動部72を作動させることにより、前記検査待機位置にある第一可動板6a及び第二可動板6bをそれぞれ揺動変位させて、基板10の上面及び下面に設けられた検査対象部13D,13Uに、第一可動板6a及び第二可動板6bのコンタクト部63をそれぞれ適度の圧力で正確に接触させることができるという利点がある。 Furthermore, by operating the swing drive parts 72 of the first inspection jig 4a and the second inspection jig 4b, the first movable plate 6a and the second movable plate 6b in the inspection waiting position can be swung and displaced, respectively, and the contact parts 63 of the first movable plate 6a and the second movable plate 6b can be brought into accurate contact with the inspection target parts 13D, 13U provided on the upper and lower surfaces of the substrate 10 with appropriate pressure, respectively.

なお、第一可動板6a及び第二可動板6bの一方を省略するとともに、これを駆動する第一昇降駆動機構5a及び第二昇降駆動機構5bの一方を省略した構造としてもよい。例えば、基板の上面側にのみ検査対象部が設けられている場合には、基板10の下方側に配設された第一可動板6aを有する第一検査治具4aと、これを駆動する第一昇降駆動機構5aとを省略した構成とすることができる。 It is also possible to omit one of the first movable plate 6a and the second movable plate 6b, and to omit one of the first lifting and lowering drive mechanism 5a and the second lifting and lowering drive mechanism 5b that drives it. For example, if the inspection target portion is provided only on the upper surface side of the substrate, the first inspection jig 4a having the first movable plate 6a arranged on the lower side of the substrate 10 and the first lifting and lowering drive mechanism 5a that drives it can be omitted.

また、上述の実施形態では、第一可動板6aおよび第二可動板6bに、コンタクト部63,63が複数個所に分離された状態でそれぞれ設置されるとともに、相隣接するコンタクト部63,63の間に、枢支部8側に向けて凹入する切欠部65が形成され、第一検査治具4a及び第二検査治具4bの支持部材7に、切欠部65内に導入される突部92を有する支持ブロック9がそれぞれ設けられた構成としている。 In addition, in the above-described embodiment, the contact portions 63, 63 are installed in a state in which they are separated into a plurality of locations on the first movable plate 6a and the second movable plate 6b, and a notch 65 that recesses toward the pivot portion 8 is formed between adjacent contact portions 63, 63, and a support block 9 having a protrusion 92 that is inserted into the notch 65 is provided on each of the support members 7 of the first inspection jig 4a and the second inspection jig 4b.

この構成によれば、支持ブロック9の突部92,92により基板10の上面及び下面をそれぞれ支持した状態で、第一可動板6a及び第二可動板6bを揺動駆動部72によって駆動することにより、基板10の下面及び上面に適度の押圧力を付与することが可能である。したがって、基板10が弾性変形し易い素材で形成されている場合においても、その上方変位及び下方変位を支持ブロック9によりそれぞれ抑制することができる。この結果、前記押圧力に応じて第一可動板6a及び第二可動板6bのコンタクト部63,63を適度に加圧することにより、このコンタクト部63,63と基板10の検査対象部13D,13Uとを適正に導通させることができる。 With this configuration, while the upper and lower surfaces of the substrate 10 are supported by the protrusions 92, 92 of the support block 9, the first movable plate 6a and the second movable plate 6b are driven by the swing drive unit 72, thereby making it possible to apply an appropriate pressing force to the upper and lower surfaces of the substrate 10. Therefore, even if the substrate 10 is made of a material that is easily elastically deformed, its upward and downward displacement can be suppressed by the support block 9. As a result, by applying an appropriate amount of pressure to the contact portions 63, 63 of the first movable plate 6a and the second movable plate 6b in response to the pressing force, it is possible to properly establish electrical continuity between the contact portions 63, 63 and the inspection target portions 13D, 13U of the substrate 10.

また、上述のように図外の吸引装置の吸引力に応じて基板10を吸着する吸着孔20が形成された吸着板21と、この吸着板21の吸着孔20から吸引された空気を吸引装置側に導出する連通孔22が形成された支持板23と、吸着板21と支持板23との間に配設されるパッキン24とを基板保持部材2に設けるとともに、パッキン24に、基板10の吸着範囲に対応した大きさを有する開口部28と、この開口部28の外周部を囲繞する囲繞部29とを設けた構造とした場合には、基板10の吸着範囲外に位置する吸着孔20と連通孔22との連通がパッキン24により遮断されることになる。このため、基板10の主要部を吸着板21に対して強固に密着させることができる。 In addition, as described above, when the substrate holding member 2 is provided with the suction plate 21 having the suction holes 20 formed therein, which suctions the substrate 10 in response to the suction force of the suction device (not shown), the support plate 23 having the communication holes 22 formed therein, which directs the air sucked through the suction holes 20 of the suction plate 21 to the suction device side, and the packing 24 disposed between the suction plate 21 and the support plate 23, and the packing 24 is provided with an opening 28 having a size corresponding to the suction range of the substrate 10 and a surrounding portion 29 surrounding the outer periphery of the opening 28, the communication between the suction holes 20 located outside the suction range of the substrate 10 and the communication holes 22 is blocked by the packing 24. Therefore, the main portion of the substrate 10 can be firmly attached to the suction plate 21.

さらに、図7に示すように、大きさの異なる開口部28a,28bを有する複数枚のパッキン24a,24bを予め取り揃えるとともに、基板10の種類に対応したパッキン24をユーザが選択して、吸着板21と、支持板23、具体的には中間板25との間に配設し得るように構成することにより、大きさが異なる各種の基板10を基板保持部材2にそれぞれ適正に保持させることができる。 Furthermore, as shown in FIG. 7, multiple packings 24a, 24b with openings 28a, 28b of different sizes are prepared in advance, and the user can select the packing 24 corresponding to the type of substrate 10 and place it between the suction plate 21 and the support plate 23, specifically the intermediate plate 25, so that various substrates 10 of different sizes can be properly held by the substrate holding member 2.

すなわち、基板保持部材2の吸着板21と中間板25とを分離した状態で、基板10の大きさに対応した開口部28を有するパッキン24を吸着板21と中間板25との間に配設することにより、基板10の大きさに対応して負圧の生成範囲を変化させることできる。このため、簡単な構成で基板保持部材2に汎用性を持たせることが可能となり、種々の大きさを有する基板10を吸着板21上に吸着させて、それぞれ適正に保持させることができる。 In other words, by disposing a gasket 24 having an opening 28 corresponding to the size of the substrate 10 between the suction plate 21 and the intermediate plate 25 of the substrate holding member 2 while the suction plate 21 and the intermediate plate 25 are separated, the range in which negative pressure is generated can be changed according to the size of the substrate 10. This makes it possible to give versatility to the substrate holding member 2 with a simple configuration, and substrates 10 of various sizes can be adsorbed onto the suction plate 21 and appropriately held.

また、第二可動板6bのコンタクト部63を一定の圧力で基板10の検査対象部13Uに接触させるように第二検査治具4bを昇降駆動する駆動シリンダからなる緩衝駆動部54を第二昇降駆動機構5bに設けてなる上述の実施形態によれば、この第二昇降駆動機構5bの緩衝駆動部54と、第二検査治具4bの揺動駆動部72とを必要に応じて選択的に作動させることにより、各種の基板10をそれぞれ適正に検査できるという利点がある。 In addition, according to the above-mentioned embodiment in which the second lifting drive mechanism 5b is provided with a buffer drive unit 54 consisting of a drive cylinder that drives the second inspection jig 4b up and down so that the contact portion 63 of the second movable plate 6b contacts the inspection target portion 13U of the substrate 10 with a constant pressure, the buffer drive unit 54 of the second lifting drive mechanism 5b and the swing drive unit 72 of the second inspection jig 4b can be selectively operated as needed, thereby providing the advantage that each of the various substrates 10 can be properly inspected.

例えばコンタクト部63に設けられたコネクタ材を弾性変形させる必要があるプローブ方式の接触端子を用いて、基板10の検査を行う場合において、支持軸81を支点に第二可動板6bを所定量だけ揺動変位させることにより、コンタクト部63を検査対象部13Uに接触させた場合には、第一可動板6aが傾斜状態となる虞がある。この結果、基板の種類によっては、検査対象部13Uにコンタクト部63を適正に接触させることができない可能性がある。 For example, when inspecting the board 10 using a probe-type contact terminal that requires elastic deformation of the connector material provided on the contact portion 63, if the second movable plate 6b is swung and displaced a predetermined amount around the support shaft 81 as a fulcrum to bring the contact portion 63 into contact with the inspection target portion 13U, there is a risk that the first movable plate 6a will be inclined. As a result, depending on the type of board, it may not be possible to properly bring the contact portion 63 into contact with the inspection target portion 13U.

したがって、上述のように第二可動板6bの下降量を、ある程度確保する必要がある場合には、揺動駆動部72の作動を停止して、第二可動板6bを水平に保持した状態で、第二昇降駆動機構5bの緩衝駆動部54を作動させ、第二検査治具4bを所定位置まで下降させることにより、コンタクト部63を検査対象部13Uに対して適正に接触させることが好ましい。 Therefore, when it is necessary to ensure a certain amount of descent of the second movable plate 6b as described above, it is preferable to stop the operation of the swing drive unit 72, hold the second movable plate 6b horizontally, and operate the buffer drive unit 54 of the second lift drive mechanism 5b to lower the second inspection jig 4b to a predetermined position, thereby bringing the contact portion 63 into proper contact with the inspection target portion 13U.

一方、第二可動板6bの下降量を、それ程大きく設定する必要がなく、かつ検査対象部13Uに対するコンタクト部63の接触圧を高精度に制御する必要がある場合には、緩衝駆動部54の作動を停止させた状態で、揺動駆動部72により支持軸81を支点に第二可動板6bを揺動変位させることにより、検査対象部13Uに対するコンタクト部63の接触圧を適正値に制御することが好ましい。 On the other hand, when it is not necessary to set the amount of descent of the second movable plate 6b so large, and it is necessary to control the contact pressure of the contact portion 63 against the inspection target portion 13U with high precision, it is preferable to control the contact pressure of the contact portion 63 against the inspection target portion 13U to an appropriate value by displacing the second movable plate 6b by swinging it around the support shaft 81 by the swing drive portion 72 while stopping the operation of the buffer drive portion 54.

さらに、基板10の検査時に、第一可動板6a及び第二可動板6bの昇降位置を高精度に制御する必要がなく、かつ検査対象部13Uに対するコンタクト部63の接触圧を、より大きく設定する必要がある場合には、第一昇降駆動機構5a及び第二昇降駆動機構5bの駆動力に応じて、コンタクト部63を検査対象部13Uに接触させることも可能である。 Furthermore, when inspecting the substrate 10, if there is no need to control the elevation positions of the first movable plate 6a and the second movable plate 6b with high precision and it is necessary to set the contact pressure of the contact portion 63 against the inspection target portion 13U to be greater, it is also possible to bring the contact portion 63 into contact with the inspection target portion 13U according to the driving force of the first elevation drive mechanism 5a and the second elevation drive mechanism 5b.

例えば、多数のプローブ端子を用いて基板10の検査を行う場合に、揺動駆動部72の作動を停止して第一可動板6a及び第二可動板6bを水平に保持した状態で、第一昇降駆動機構5a及び第二昇降駆動機構5bの回転駆動部51を作動させて、第一検査治具4a及び第二検査治具4bを昇降変位させることにより、コンタクト部63を検査対象部13Uに接触させることもできる。 For example, when inspecting the substrate 10 using multiple probe terminals, the operation of the swing drive unit 72 can be stopped and the first movable plate 6a and the second movable plate 6b can be held horizontally, while the rotation drive units 51 of the first lifting drive mechanism 5a and the second lifting drive mechanism 5b can be operated to raise and lower the first inspection jig 4a and the second inspection jig 4b, thereby bringing the contact portion 63 into contact with the inspection target portion 13U.

このように本発明に係る基板検査装置は、基板10の種類及びコンタクト部63の構造に応じ、基板10の検査時に使用する駆動部を適宜選択して使用することにより、各種の基板10をそれぞれ適正に検査することが可能であるため、優れた汎用性を有するという利点がある。 In this way, the board inspection device of the present invention has the advantage of being highly versatile, since it is possible to properly inspect each type of board 10 by appropriately selecting and using the drive unit used when inspecting the board 10 depending on the type of board 10 and the structure of the contact portion 63.

また、上述の実施形態では、昇降板53b及び第二検査治具4bをその自重に抗して上方に付勢する引張りばねからなる左右一対の付勢部材55,55を、緩衝駆動部54,54の間に配設しているため、この緩衝駆動部54,54として小型のエアシリンダを用いた場合でも、第二検査治具4b等を容易かつ迅速に昇降変位させることができる。 In addition, in the above-described embodiment, a pair of left and right biasing members 55, 55 consisting of tension springs that bias the lift plate 53b and the second inspection jig 4b upward against their own weight are disposed between the buffer drive units 54, 54, so that the second inspection jig 4b etc. can be easily and quickly raised and lowered even when small air cylinders are used as the buffer drive units 54, 54.

なお、緩衝駆動部54,54を省略した構造としてもよく、あるいは基板10の上方に位置する第二昇降駆動機構5bと、基板10の上方に位置する第二昇降駆動機構5bとの両方に、緩衝駆動部54,54をそれぞれ配設した構造としてもよい。さらに、下方の第一昇降駆動機構5aのみに緩衝駆動部54,54を配設した構造とすることも可能である。 The buffer drive units 54, 54 may be omitted, or the buffer drive units 54, 54 may be provided on both the second lifting drive mechanism 5b located above the substrate 10 and the second lifting drive mechanism 5b located above the substrate 10. Furthermore, it is also possible to provide the buffer drive units 54, 54 only on the lower first lifting drive mechanism 5a.

すなわち、本発明の一例に係る検査治具は、検査対象の基板を保持する基板保持部材と、当該基板保持部材に保持された基板の検査対象部に接触するコンタクト部を有する可動板と、当該可動板を支持する支持部材とを有する検査治具と、当該検査治具を昇降変位させて前記コンタクト部が前記検査対象部に近接した検査待機位置に前記可動板を移動させる昇降駆動機構とを備え、前記支持部材には、前記可動板を揺動可能に支持する支持軸を備えた枢支部と、前記支持軸を支点に前記可動板を揺動変位させて前記コンタクト部を前記検査対象部に接触させる揺動駆動部とが設けられたものである。 That is, an inspection jig according to one embodiment of the present invention includes an inspection jig having a board holding member that holds the board to be inspected, a movable plate having a contact portion that contacts the inspection target portion of the board held by the board holding member, and a support member that supports the movable plate, and an elevation drive mechanism that raises and lowers the inspection jig to move the movable plate to an inspection waiting position where the contact portion is close to the inspection target portion, and the support member is provided with a pivot portion having a support shaft that supports the movable plate so that it can be oscillated, and a swing drive portion that oscillates and displaces the movable plate about the support shaft as a fulcrum to bring the contact portion into contact with the inspection target portion.

この構成によれば、昇降駆動機構により検査治具を初期位置から検査待機位置に容易かつ迅速に移動させることができる。そして、揺動駆動部によって支持軸を支点に可動板を揺動変位させることにより、コンタクト部を検査対象部に適度の圧力で接触させて、基板の検査を正確に行うことができる。 With this configuration, the lift drive mechanism can easily and quickly move the inspection jig from the initial position to the inspection standby position. Then, the swing drive unit swings and displaces the movable plate around the support shaft as a fulcrum, bringing the contact part into contact with the inspection target part with an appropriate amount of pressure, allowing accurate inspection of the board.

前記コンタクト部には、導電ゴム製の導
電コネクタ材が配設された構成としてもよい。
The contact portion may be provided with a conductive connector material made of conductive rubber.

この構成によれば、柔軟な導電コネクタ材を基板の検査対象部に面接触させることにより、細かな電極に対して高い接触安定性が得られるとともに、高い検査精度が得られる等の利点がある。また、微細電極でも位置ずれに対して広い許容幅を有し、かつ基板の検査対象部にダメージを与えることがないとともに、検査治具を軽量かつ薄型に形成できる等の利点がある。しかも、検査待機位置にある検査治具を揺動駆動部により支持軸を支点に揺動変位させて、上述のようにコンタクト部を検査対象部に軽い圧力で接触させ得るように構成することにより、導電コネクタ材の損傷を容易に抑制することができる。 This configuration has the advantages of providing high contact stability for fine electrodes and high inspection accuracy by bringing the flexible conductive connector material into surface contact with the inspection target portion of the board. In addition, it has the advantages of having a wide tolerance for positional deviation even with fine electrodes, not damaging the inspection target portion of the board, and allowing the inspection jig to be made lightweight and thin. Moreover, by configuring the inspection jig in the inspection standby position to be oscillated and displaced around the support shaft by the oscillating drive unit, so that the contact portion can be brought into contact with the inspection target portion with light pressure as described above, damage to the conductive connector material can be easily suppressed.

また、前記検査治具は、前記基板の下方側に配設された第一可動板を有する第一検査治具と、前記基板の上方側に配設された第二可動板を有する第二検査治具とを備え、前記昇降駆動機構は、前記第一検査治具を昇降駆動する第一昇降駆動機構と、前記第二検査治具を昇降駆動する第二昇降駆動機構とを備えていることが好ましい。 Furthermore, it is preferable that the inspection jig includes a first inspection jig having a first movable plate disposed below the substrate, and a second inspection jig having a second movable plate disposed above the substrate, and the lifting and lowering mechanism includes a first lifting and lowering mechanism that drives the first inspection jig to lift and lower, and a second lifting and lowering mechanism that drives the second inspection jig to lift and lower.

この構成によれば、第一昇降駆動機構及び第二昇降駆動機構により、第一可動板及び第二可動板を基板に近接させた検査待機位置にそれぞれ迅速に移動させることができる。しかも、第一検査治具及び第二検査治具の揺動駆動部により第一可動板及び第二可動板をそれぞれ揺動変位させて、基板の上面及び下面に設けられた検査対象部に第一可動板及び第二可動板のコンタクト部をそれぞれ適度の圧力で正確に接触させることができるという利点がある。 With this configuration, the first and second movable plates can be quickly moved to an inspection standby position close to the substrate by the first and second lifting drive mechanisms. Moreover, the first and second movable plates can be oscillated and displaced by the swing drive parts of the first and second inspection jigs, respectively, which has the advantage that the contact parts of the first and second movable plates can be accurately brought into contact with the inspection target parts provided on the upper and lower surfaces of the substrate with an appropriate amount of pressure.

また、前記第一可動板および前記第二可動板には、前記コンタクト部が複数個所に分離された状態でそれぞれ設置されるとともに、相隣接する前記コンタクト部の間に、前記枢支部側に向けて凹入する切欠部が形成され、前記第一検査治具及び前記第二検査治具の支持部材には、前記基板を支持する支持ブロックがそれぞれ設けられ、当該支持ブロックは、前記切欠部内に導入される突部を有した構成としてもよい。 Furthermore, the contact parts may be installed in a state in which they are separated into a plurality of locations on the first movable plate and the second movable plate, and a notch recessed toward the pivot part may be formed between adjacent contact parts, and the support members of the first inspection jig and the second inspection jig may each be provided with a support block supporting the substrate, and the support block may have a protrusion that is inserted into the notch.

この構成によれば、支持ブロックの突部により基板の上面及び下面をそれぞれ支持した状態で、第一可動板及び第二可動板を揺動駆動部によって駆動することにより、基板の下面及び上面に適度の押圧力を付与することができる。このため、基板が弾性変形し易い素材で形成されている場合においても、その上方変位及び下方変位を支持ブロックによりそれぞれ抑制することができる。したがって、前記押圧力に応じて第一可動板及び第二可動板のコンタクト部を適度に加圧することにより、このコンタクト部と基板の検査対象部とを適正に導通させることができる。 With this configuration, while the upper and lower surfaces of the substrate are supported by the protrusions of the support block, the first and second movable plates are driven by the swing drive unit, thereby applying an appropriate pressing force to the upper and lower surfaces of the substrate. Therefore, even if the substrate is made of a material that is prone to elastic deformation, the upward and downward displacement of the substrate can be suppressed by the support block. Therefore, by applying an appropriate amount of pressure to the contact portions of the first and second movable plates in response to the pressing force, proper electrical continuity can be established between the contact portions and the portion of the substrate to be inspected.

また、前記基板保持部材は、吸引装置の吸引力に応じて前記基板を吸着する吸着孔が形成された吸着板と、当該吸着板の吸着孔から吸引された空気を前記吸引装置側に導出する連通孔が形成された支持板と、前記吸着板と前記支持板との間に配設されるパッキンとを有し、当該パッキンには、前記基板の吸着範囲に対応した大きさを有する開口部と、当該開口部の外周部を囲繞する囲繞部とが設けられた構成とすることが好ましい。 Furthermore, the substrate holding member preferably has a suction plate having suction holes formed therein that suctions the substrate in response to the suction force of a suction device, a support plate having a communication hole formed therein that guides the air sucked through the suction holes of the suction plate to the suction device side, and a packing disposed between the suction plate and the support plate, and the packing is preferably configured to have an opening having a size corresponding to the suction range of the substrate and a surrounding portion surrounding the outer periphery of the opening.

この構成によれば、基板の吸着範囲外に位置する吸着孔と連通孔との連通がパッキンにより遮断されるため、基板の主要部を吸着板に対して強固に密着させることができる。しかも、大きさの異なる開口部を有する複数枚のパッキンを予め取り揃えるとともに、基板の種類に対応したパッキンをユーザが選択して吸着板と支持板との間に配設することにより、大きさが異なる各種の基板を基板保持部材にそれぞれ適正に保持させることができる。 With this configuration, the packing blocks communication between the suction holes located outside the suction range of the substrate and the communication holes, allowing the main part of the substrate to be firmly attached to the suction plate. Moreover, by stocking multiple packing sheets with openings of different sizes in advance and allowing the user to select a packing that corresponds to the type of substrate and place it between the suction plate and the support plate, various substrates of different sizes can be properly held by the substrate holding member.

また、前記昇降駆動機構には、前記コンタクト部を一定の圧力で前記検査対象部に接触させるように前記検査治具を昇降駆動する駆動シリンダからなる緩衝駆動部が、さらに設けられた構成としてもよい。 The lifting and lowering mechanism may further include a buffer drive unit consisting of a drive cylinder that lifts and lowers the inspection jig so that the contact portion contacts the inspection target portion with a constant pressure.

この構成によれば、基板の検査時に、昇降駆動機構と第二検査治具の揺動駆動部とを必要に応じて選択的に作動させることにより、各種の基板をそれぞれ適正に検査できるという利点がある。このように基板の種類及びコンタクト部の構造に応じて、基板の検査に使用する駆動部を使い分けることにより、各種の基板をそれぞれ適正に検査することが可能であるため、優れた汎用性を有するという利点がある。 This configuration has the advantage that various types of boards can be properly inspected by selectively operating the lifting drive mechanism and the swing drive unit of the second inspection jig as needed during board inspection. In this way, by using different drive units for board inspection depending on the type of board and the structure of the contact part, it is possible to properly inspect various types of boards, which has the advantage of excellent versatility.

このような構成の基板検査治具によれば、基板の検査対象部及び検査治具のコンタクト部の損傷を抑制することが容易である。 A board inspection jig with this configuration makes it easy to prevent damage to the part of the board to be inspected and the contact part of the inspection jig.
