Description

【０００１】
【発明の属する技術分野】
本発明は、配線基板や半導体集積回路等に備えられた突起電極に接触される接触子及びこれを用いた電気的接続装置に関する。
【０００２】
【従来の技術】
配線基板、接続基板、半導体集積回路、表示用基板、電子部品等の被接続体は、一般に、検査装置の電気回路、配線基板、接続ランド又は配線を有する他の配線基板、配線基板を他の接続体に接続する接続基板等、相手側の接続体に電気的に接続される複数の突起電極を備えている。
【０００３】
この種の突起電極は、球状、円錐状、角錐状、球状の頂部を有する円錐状又は角錐状等の形状を有しており、またプローブ、プローブ要素等の接触子を用いて相手側の接続体に電気的に接続される。
【０００４】
上記のような接触子の１つとして、厚さ方向に貫通する導電性のスルーホールを有するランド部と、該ランド部から前記スルーホールの開放部を螺旋状に伸びる帯状の接触部とを含み、接触部を曲率半径がランド部側ほど大きい螺旋状とし、そのような螺旋状の接触部を被接続体の突起電極に押圧する構造としたものがある（特許文献１）。
【０００５】
特許文献１：特開２０００２−１７５８５９
【０００６】
上記従来の接触子においては、接触部を被接続体の突起電極に押圧したとき、接触部全体が捩れられる共に、接触部がランド部に垂直な方向に湾曲されることにより、接触子と突起電極との電気的接続状態を安定化させている。
【０００７】
【解決しようとする課題】
しかし、螺旋状の接触部を備えた接触子においては、ランド部に垂直な方向への接触部の湾曲により、接触部のうち、ランド部側の領域（外側端領域）、特にランド部に続く箇所に大きな負荷が作用し、その箇所において急激に曲げられる。このため、従来の接触子では、接触部がランド部に続く外側端領域において破損する事故が多い。
【０００８】
本発明の目的は、接触部の破損事故を少なくすることにある。
【０００９】
【解決手段、作用、効果】
本発明に係る接触子は、穴状の空間を有するランド部と、該ランド部から前記空間内を螺旋状に伸びる少なくとも１つの接触部とを含む。前記接触部は、前記ランド部の厚さ方向と直角の面内における第１の方向への長さ寸法が前記第１の方向と直角の第２の方向への前記接触部の長さ寸法より大きい外側端領域を備えており、この外側端領域の一端部において前記ランド部に続いている。
【００１０】
接触部が被接触体の接続箇所に押圧されると、接触部がランド部と直角の方向に湾曲される。これにより、接触子と被接続体との電気的接続状態が安定する。
【００１１】
本発明に係る接触子においては、第１の方向への外側端領域の長さ寸法が第２の方向への接触部のそれより大きいから、接触部に作用する負荷が接触部の長い範囲に分散され、接触部はそのような長い範囲において湾曲される。このため、接触部の破損が減少する。
【００１２】
前記外側端領域は前記ランド部から離れるほど小さい幅寸法を有していてもよい。そのようにすれば、外側端領域の機械的強度がランド部側の箇所ほど大きくなり、したがって外側端領域における破損が著しく低減する。
【００１３】
前記接触部は、さらに、前記外側端領域の反ランド部側に続く延長領域を備え、前記延長領域の外側端領域側の端部は前記外側端領域の反ランド部側の幅寸法と同じ幅寸法を有していてもよい。そのようにすれば、荷重が外側領域と延長領域との境界付近に集中することがなく、したがって外側端領域と延長領域との境界付近における破損が著しく低減する。
【００１４】
接触子は複数の前記接接触子を備えていてもよい。この場合、複数の接触子を回転対称に配置してもよい。請求項１から４のいずれか１項に記載の接触子。
【００１５】
前記ランド部は、前記第１の方向に長い長円形の形状を有していてもよい。また、前前記ランド部は前記第１の方向における端部に貫通穴を有していてもよい。さらに、前記ランド部及び前記接触部は導電性材料により一体的に製作されていてもよい。
【００１６】
本発明に係る電気的接続装置は、電気絶縁性の基板と、上記のような少なくとも１つの導電性の接触子とを含む。前記基板はこれの一方の面側に開放する少なくとも１つの凹所を有し、前記接触子は、前記接触部が前記凹所の開放部に位置するように前記基板の一方の面に配置されている。この電気的接続装置においても、接触子は、上記のように作用するから、上記のような効果を奏する。
【００１７】
前記基板は、さらに、前記凹所の近傍にあって前記第１の方向における一端部に対応する箇所に形成された導電性のスルーホールと、該スルーホールに電気的に接続された配線部とを含み、前記接触子は前記スルーホールに電気的に接続されていてもよい。
【００１８】
【発明の実施の形態】
図１を参照するに、接触子１０は、導電性の金属材料、好ましくは弾性変形可能の金属材料により、全体に目の形を有する薄い板の形に製作されている。接触子１０は、長円形の形を有するランド部１２と、ランド部１２に一体に続く接触部１４とを含む。
【００１９】
ランド部１２は、長円形の中央領域に長円形をした穴状の空間１６を有していると共に、長円形の長軸方向における各端部に穴１８を有している。穴１８は、一端部にのみ設けてもよいし、長円形の短軸方向における端部のような他の箇所に設けてもよく、さらには貫通穴を設けなくてもよい。
【００２０】
接触部１４は、ランド部１２から空間１６内を螺旋状に伸びている。接触部１４のうち、螺旋の最も外側に位置する外側端領域２０はランド部１２から弧状に湾曲しつつ長円形の長軸方向に伸びており、また外側端領域２０に続く帯状の延長領域２２は螺旋状に伸びている。接触部１４は、外側端領域２０の一端部においてランド部１２に一体的に続いている。
【００２１】
長円形の長軸方向における外側端領域２０の長さ寸法Ｌ１は、長円形の短軸方向における接触部１４の長さ寸法Ｌ２より大きい。外側端領域２０の幅寸法はランド部１２から離れるほど小さく、延長領域２２の幅寸法は外側端領域２０の反ランド部側の幅寸法とほぼ同じである。
【００２２】
図２を参照するに、接触子１０は、基板２４の一方の面に組み付けられて、基板２４と共に電気的接続装置を構成する。
【００２３】
図２は、１つの接触子１０を基板２４に配置しているにすぎない。しかし、実際には、配線基板、接続基板、半導体集積回路、表示用基板、電子部品のいずれであっても、被接続体が２以上の接触箇所２６を備えていることから、一般に、電気的組立装置は、複数の接触子１０を基板２４に組み付けている。接触箇所２６は、図示の例では、球状の突起電極であるが、これに限定されない。
【００２４】
基板２４は、平板状の板部材３０と、複数の接触子１４に個々に対応されて板部材３０の一方の面に形成された複数の凹所３２と、凹所３２に個々に対応されて板部材３０を厚さ方向に貫通する複数対のスルーホール３４と、スルーホール３４の対に個々に対応された複数の配線部３６とを含む配線基板とされている。
【００２５】
基板２４は、図示してはいないが、テスターの電気回路に接続される複数の接続ランドを板部材３０の外周縁部に備えている。基板２４の平面形状は、円形であってもよいし、長円形、矩形等の他の形状であってもよい。
【００２６】
板部材３０は、ガラス入りエポキシのような電気絶縁材料により製作されている。各凹所３２は、平面的に見て、接触子１０の接触部１４とほぼ同じ大きさを有しており、基板２４の一方の面に開放している。しかし、凹所３２は、貫通穴であってもよい。
【００２７】
各対のスルーホール３４は、接触子１０の穴１８に個々に対応されており、したがって凹所３２を間にして、接触子１０の両穴１８と同じ寸法だけ互いに離間されている。各配線部３６は、基板２４のテスターランドと、対応するスルーホール３４の一方とに電気的に接続されている。
【００２８】
接触子１０は、平面的に見て、接触部１４が凹所３２の開放部に位置し、穴１８がスルーホール３４と一致してスルーホール３４に電気的に接続されるように、基板２４の一方の面に装着されている。
【００２９】
図２に示す例では、接触子１０と、スルーホール３４と、配線部３６とは、一体的に製作されている。
【００３０】
上記のような電気的接続装置は、凹所３２、スルーホール３４及び配線部３６を備える基板２４を一般的な方法により製作し、次いで接触子１０をリソグラフィー技術のような電気メッキにより基板２４に形成することにより、製造することができる。
【００３１】
しかし、接触子１０と基板２４とを別個に製作し、次いで接触子１０がスルーホール３４に電気的に接続した状態に、接触子１０を基板２４に装着するようにしてもよい。
【００３２】
接触子１０と突起電極２６とを電気的に接続するとき、接触部１０と突起電極２６とが相対的に押圧される。これにより、接触部１４がランド部１２と直角の方向（図２において下方）に湾曲される。この状態においては、突起電極２６が接触部１４の長い領域にわたって接触するから、接触子１０と突起電極２６とが確実に電気的に接触子、両者１０及び２６の電気的接続状態が安定する。
【００３３】
図２に示すように、接触子１０のランド部１２は基板２４の一方の面に取り付けられる装着部として用いられ、接触部１４は被接続体の突起電極２６に押圧される接触片として用いられる。また、接触子１０の最外側端領域２０は穴１６内を伸びて一端部においてランド部１２に一体的に続く撓み部として作用し、延長領域２２は撓み部２０の反ランド部側端部に一体的に続く接触片部として作用する。
【００３４】
接触子１０は、第１の方向への外側端領域２０の長さ寸法Ｌ１が第２の方向への接触部１４の長さ寸法Ｌ２より大きいから、接触部１４に作用する負荷が接触部１４の長い範囲に分散され、接触部１４は、そのような長い範囲において湾曲される。このため、接触部１４の破損が減少する。
【００３５】
接触子１０においては、外側端領域２０がランド部１２から離れるほど小さい幅寸法を有しているから、外側端領域２０の機械的強度がランド部側の箇所ほど大きくなり、したがって外側端領域２０における破損が著しく低減する。
【００３６】
さらに、接触子１０においては、延長領域２２が外側端領域２０の反ランド部側の幅寸法とほぼ同じ一定の幅寸法を有しているから、荷重が外側領域２０と延長領域２２との境界付近に集中することがなく、したがって外側端領域２０と延長領域２２との境界付近における破損が著しく低減する。
【００３７】
上記のような作用効果は、延長領域２２の幅寸法が反外側端領域側ほど小さい場合にも生じる。したがって、延長領域２２の幅寸法をそのようにしてもよい。
【００３８】
上記実施例では、１つの接触部１４を備えているにすぎないが、図３に示すように複数の接触部１４，１４を回転対称に備えていてもよい。
【００３９】
また、１つの突起電極を備える被接続体の場合、電気的接続装置は、基板のような適宜な支持体に１つの接触子を組み付けてもよい。
【００４０】
本発明は、上記実施例に限定されず、その趣旨を逸脱しない限り、種々変更することができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a contact that comes into contact with a protruding electrode provided on a wiring board, a semiconductor integrated circuit, or the like, and an electrical connection device using the contact.
[0002]
[Prior art]
Wiring boards, connection boards, semiconductor integrated circuits, display boards, connected parts such as electronic components, etc., are generally connected to an electric circuit of an inspection device, a wiring board, another wiring board having connection lands or wiring, and another wiring board. It has a plurality of protruding electrodes that are electrically connected to a connection body on the other side, such as a connection board connected to the connection body.
[0003]
This type of projecting electrode has a shape such as a spherical shape, a conical shape, a pyramid shape, a conical shape having a spherical apex or a pyramid shape, and a connection of a mating side using a contact such as a probe or a probe element. It is electrically connected to the body.
[0004]
As one of the above-mentioned contacts, a land portion having a conductive through hole penetrating in a thickness direction, and a strip-shaped contact portion spirally extending from the land portion to the opening of the through hole are included. In addition, there is a structure in which a contact portion is formed in a spiral shape having a larger radius of curvature toward the land portion, and such a spiral contact portion is pressed against a protruding electrode of a connected body (Patent Document 1).
[0005]
Patent Document 1: JP-A-20002-175859
[0006]
In the above-described conventional contact, when the contact portion is pressed against the projection electrode of the connected body, the contact portion is entirely twisted and the contact portion is bent in a direction perpendicular to the land portion, so that the contact portion and the projection are bent. The electrical connection state with the electrode is stabilized.
[0007]
[Problem to be solved]
However, in a contact having a spiral contact portion, the contact portion bends in a direction perpendicular to the land portion, so that the contact portion has a region on the land portion side (outer end region), particularly a region following the land portion. A large load acts on a point, and the point is sharply bent. For this reason, in the conventional contact, there are many accidents in which the contact portion is broken in the outer end region following the land portion.
[0008]
An object of the present invention is to reduce the number of accidents at which a contact portion is broken.
[0009]
[Solutions, actions, and effects]
A contact according to the present invention includes a land having a hole-shaped space, and at least one contact extending spirally from the land in the space. The contact portion has a length dimension in a first direction in a plane perpendicular to a thickness direction of the land portion, which is longer than a length dimension of the contact portion in a second direction perpendicular to the first direction. A large outer end region is provided, which follows the land at one end of the outer end region.
[0010]
When the contact portion is pressed against the connection portion of the contacted body, the contact portion is bent in a direction perpendicular to the land. This stabilizes the electrical connection between the contact and the connected body.
[0011]
In the contact according to the present invention, since the length dimension of the outer end region in the first direction is larger than that of the contact portion in the second direction, the load acting on the contact portion is within a long range of the contact portion. Dispersed and the contacts curved in such a long range. Therefore, damage to the contact portion is reduced.
[0012]
The outer end region may have a smaller width dimension as being away from the land portion. By doing so, the mechanical strength of the outer end region increases toward the land portion side, so that breakage in the outer end region is significantly reduced.
[0013]
The contact portion further includes an extension region following the non-land portion side of the outside end region, and an end of the extension region on the outside end region side has the same width as a width dimension of the outside end region on the non-land portion side. It may have dimensions. By doing so, the load does not concentrate near the boundary between the outer region and the extension region, and therefore, damage near the boundary between the outer end region and the extension region is significantly reduced.
[0014]
The contact may include a plurality of the contact contacts. In this case, a plurality of contacts may be arranged rotationally symmetrically. The contact according to any one of claims 1 to 4.
[0015]
The land portion may have an oval shape that is long in the first direction. Further, the front land portion may have a through hole at an end in the first direction. Further, the land portion and the contact portion may be integrally formed of a conductive material.
[0016]
An electrical connection device according to the present invention includes an electrically insulating substrate and at least one conductive contact as described above. The substrate has at least one recess opening to one side of the substrate, and the contact is arranged on one surface of the substrate such that the contact portion is located at an opening of the recess. ing. Also in this electrical connection device, the contact works as described above, and thus has the above-described effects.
[0017]
The substrate further includes a conductive through-hole formed at a location near the recess and corresponding to one end in the first direction, and a wiring portion electrically connected to the through-hole. And the contact may be electrically connected to the through hole.
[0018]
BEST MODE FOR CARRYING OUT THE INVENTION
Referring to FIG. 1, the contact 10 is made of a conductive metal material, preferably an elastically deformable metal material, in the form of a thin plate having an overall eye shape. The contact 10 includes a land portion 12 having an oval shape, and a contact portion 14 integrally formed with the land portion 12.
[0019]
The land portion 12 has an oval hole-shaped space 16 in an oval central region, and a hole 18 at each end in the long axis direction of the oval. The hole 18 may be provided only at one end, may be provided at another location such as the end in the oval short axis direction, and may not be provided with a through hole.
[0020]
The contact portion 14 extends spirally in the space 16 from the land portion 12. The outer end region 20 of the contact portion 14, which is located at the outermost side of the spiral, extends in the long axis direction of the oval while being curved in an arc shape from the land portion 12, and has a strip-shaped extension region 22 following the outer end region 20. Is spirally extending. The contact portion 14 integrally follows the land portion 12 at one end of the outer end region 20.
[0021]
The length L1 of the outer end region 20 in the long axis direction of the oval is larger than the length L2 of the contact portion 14 in the short axis direction of the oval. The width of the outer end region 20 is smaller as the distance from the land portion 12 increases, and the width of the extension region 22 is substantially the same as the width of the outer end region 20 on the side opposite to the land.
[0022]
Referring to FIG. 2, the contact 10 is assembled on one surface of the substrate 24 and forms an electrical connection device together with the substrate 24.
[0023]
FIG. 2 merely places one contact 10 on the substrate 24. However, in practice, in any case of a wiring substrate, a connection substrate, a semiconductor integrated circuit, a display substrate, and an electronic component, since a connected body has two or more contact portions 26, generally, The assembling apparatus assembles the plurality of contacts 10 on the substrate 24. The contact portion 26 is a spherical projection electrode in the illustrated example, but is not limited to this.
[0024]
The substrate 24 has a flat plate member 30, a plurality of recesses 32 respectively formed on one surface of the plate member 30 corresponding to the plurality of contacts 14, and a plurality of recesses 32 respectively formed on one surface of the plate member 30. The wiring board includes a plurality of pairs of through holes 34 penetrating the plate member 30 in the thickness direction and a plurality of wiring portions 36 individually corresponding to the pairs of the through holes 34.
[0025]
Although not shown, the board 24 has a plurality of connection lands connected to an electric circuit of the tester on an outer peripheral edge of the plate member 30. The planar shape of the substrate 24 may be circular, or may be another shape such as an oval or a rectangle.
[0026]
The plate member 30 is made of an electrically insulating material such as epoxy with glass. Each recess 32 has substantially the same size as the contact portion 14 of the contact 10 in a plan view, and is open to one surface of the substrate 24. However, the recess 32 may be a through hole.
[0027]
Each pair of through-holes 34 is individually associated with a hole 18 in the contact 10 and is therefore spaced apart from the recess 18 by the same size as the holes 18 in the contact 10. Each wiring portion 36 is electrically connected to a tester land of the substrate 24 and one of the corresponding through holes 34.
[0028]
The contact 10 is mounted on the substrate 24 such that the contact portion 14 is located at the open portion of the recess 32 and the hole 18 coincides with the through hole 34 and is electrically connected to the through hole 34 in plan view. Is mounted on one side.
[0029]
In the example shown in FIG. 2, the contact 10, the through hole 34, and the wiring portion 36 are integrally manufactured.
[0030]
In the electrical connection device as described above, the substrate 24 having the recesses 32, the through holes 34, and the wiring portions 36 is manufactured by a general method, and then the contacts 10 are formed on the substrate 24 by electroplating such as lithography. By forming, it can be manufactured.
[0031]
However, the contact 10 and the substrate 24 may be manufactured separately, and then the contact 10 may be mounted on the substrate 24 with the contact 10 electrically connected to the through hole 34.
[0032]
When the contact 10 and the protruding electrode 26 are electrically connected, the contact portion 10 and the protruding electrode 26 are relatively pressed. Thereby, the contact portion 14 is curved in a direction perpendicular to the land portion 12 (downward in FIG. 2). In this state, since the protruding electrode 26 is in contact with the contact region 14 over a long area, the contact 10 and the protruding electrode 26 are surely electrically contacted, and the electrical connection between the two 10 and 26 is stabilized.
[0033]
As shown in FIG. 2, the land portion 12 of the contact 10 is used as a mounting portion attached to one surface of the substrate 24, and the contact portion 14 is used as a contact piece pressed by the protruding electrode 26 of the connected body. . Further, the outermost end region 20 of the contact 10 extends in the hole 16 and acts at one end as a bending portion integrally following the land portion 12, and the extension region 22 is formed at the end of the bending portion 20 on the side opposite to the land portion. It acts as an integral contact piece.
[0034]
Since the length L1 of the outer end region 20 in the first direction is larger than the length L2 of the contact portion 14 in the second direction, the load acting on the contact portion 14 is reduced. And the contact portion 14 is curved in such a long range. Therefore, the damage of the contact portion 14 is reduced.
[0035]
In the contact 10, the outer end region 20 has a smaller width dimension as the distance from the land portion 12 increases, so that the mechanical strength of the outer end region 20 increases toward the land portion side. Breakage is significantly reduced.
[0036]
Further, in the contact 10, since the extended region 22 has a constant width substantially equal to the width of the outer end region 20 on the side opposite to the land, the load is applied to the boundary between the outer region 20 and the extended region 22. Therefore, damage near the boundary between the outer end region 20 and the extension region 22 is significantly reduced.
[0037]
The above operation and effect also occur when the width dimension of the extension region 22 is smaller on the side opposite to the outer end region. Therefore, the width dimension of the extension region 22 may be set as such.
[0038]
In the above embodiment, only one contact portion 14 is provided, but a plurality of contact portions 14, 14 may be provided rotationally symmetrically as shown in FIG.
[0039]
In the case of a connected object having one protruding electrode, the electrical connection device may be configured such that one contact is assembled to an appropriate support such as a substrate.
[0040]
The present invention is not limited to the above-described embodiment, and can be variously modified without departing from the gist thereof.
