Description

本発明は、吸着フレーム部材、これを用いたシールドフレーム部材及びプリント基板の製造方法に関する。   The present invention relates to a suction frame member, a shield frame member using the same, and a method for manufacturing a printed circuit board.

近年、携帯電話やノート型PCなどの携帯情報端末において、通話機能や文書作成機能といったそれぞれの基本機能に各種機能を追加した多機能化が進んでいる。例えば、携帯電話ではメールの送受信からウェブ閲覧、カメラ撮影、GPS(Global Positioning System)機能、テレビ視聴、ゲーム機能といった機能が次々と付加されている。こうした機能は携帯情報端末が利用者の生活に浸透するに従い、高性能化が進んでいる。例えばカメラ機能では、数万程度であった静止画の画素数が数百万画素まで向上し、更には動画撮影まで可能となっている。   In recent years, in portable information terminals such as mobile phones and notebook PCs, multi-functionalization has been progressing by adding various functions to each basic function such as a call function and a document creation function. For example, mobile phones are successively added with functions such as mail transmission / reception, web browsing, camera shooting, GPS (Global Positioning System) function, TV viewing, and game function. These functions have been improved in performance as portable information terminals have penetrated the lives of users. For example, in the camera function, the number of pixels of a still image, which has been about tens of thousands, has been improved to millions of pixels, and even movie shooting is possible.

前述の多機能化・高機能化に伴い、携帯情報端末では、テレビアンテナや、Bluetoothアンテナ、GPSアンテナ、RFID(Radio Frequency Identification)アンテナなどの用途(周波数)の異なる電波を発する電子部品が隣接して実装されている。そのため、LSI(Large Scale Integration)の動作クロック周波数が高速化し、電気的に非常に過密な状態になっている。こうした状態下では、携帯情報端末のプリント基板上に配置された電子部品が他の電子部品に電気的に悪影響を与え、機器の誤動作を招くおそれがある。そのため、電子部品間の電磁遮蔽を行うシールドフレーム部材は必須になっている。   With the above-mentioned multi-functionality and high functionality, portable information terminals are adjacent to electronic components that emit radio waves with different uses (frequency) such as TV antennas, Bluetooth antennas, GPS antennas, and RFID (Radio Frequency Identification) antennas. Has been implemented. For this reason, the operating clock frequency of LSI (Large Scale Integration) is increased, and the circuit is electrically very dense. Under such a state, the electronic components arranged on the printed circuit board of the portable information terminal may adversely affect other electronic components, resulting in malfunction of the device. Therefore, a shield frame member that performs electromagnetic shielding between electronic components is essential.

一方、前述の多機能化・高機能化に伴い、携帯情報端末が大型化してしまうと、その携帯性が損なわれ、利用者に受け入れられなくなる。そのため、携帯情報端末の各構成部品は、更なる小型化・低背化や機能統合が必要となっている。シールドフレーム部材でも、低背化や、各電子部品の周辺に個別に配置していた複数のシールドフレーム部材を一体化する必要がある。一体化により1つのシールドフレーム部材としてサイズは大きくなるが、プリント基板との接合面積が複数シールドフレーム部材を配置していた場合に比べ低減する。従って、プリント基板、最終的には携帯情報端末の小型化に繋がる。   On the other hand, if the portable information terminal is enlarged with the above-mentioned multi-functionality / high functionality, the portability is impaired and the portable information terminal cannot be accepted by the user. For this reason, each component of the portable information terminal is required to be further reduced in size and height and integrated in function. Even with the shield frame member, it is necessary to reduce the height and to integrate a plurality of shield frame members that are individually arranged around each electronic component. Although integration increases the size of one shield frame member, the bonding area with the printed circuit board is reduced as compared with the case where a plurality of shield frame members are arranged. Therefore, it leads to miniaturization of the printed circuit board, and finally the portable information terminal.

こうした要求に対し、例えば特許文献1には、シールドフレーム部材を低背化できる吸着フレーム部材及びこれを搭載したプリント基板の製造方法が開示されている。図13Aに示すように、特許文献1に記載された吸着フレーム部材11は、プリント基板に搭載する場合、枠状のフレーム部材2に着脱可能な吸着部材30が装着されている。そして、図13Bに示すように、吸着部材30の天面部を吸着ヘッド7で吸着し、吸着ヘッド7により吸着フレーム部材11をプリント基板5上に搭載する。その後、半田付けされ、吸着フレーム部材11のフレーム部材2はプリント基板5と物理的、電気的に接続される。半田付け工程後、吸着部材30は取り外され(図13C)、カバー部材4をフレーム部材2に取り付けて(図13D)、電磁遮蔽を行うシールドフレーム部材12が構成される。   In response to such a demand, for example, Patent Document 1 discloses a suction frame member that can reduce the height of the shield frame member and a method of manufacturing a printed circuit board on which the suction frame member is mounted. As shown in FIG. 13A, when the suction frame member 11 described in Patent Document 1 is mounted on a printed circuit board, a removable suction member 30 is attached to the frame-shaped frame member 2. Then, as illustrated in FIG. 13B, the top surface portion of the suction member 30 is sucked by the suction head 7, and the suction frame member 11 is mounted on the printed circuit board 5 by the suction head 7. Thereafter, soldering is performed, and the frame member 2 of the suction frame member 11 is physically and electrically connected to the printed circuit board 5. After the soldering process, the adsorbing member 30 is removed (FIG. 13C), the cover member 4 is attached to the frame member 2 (FIG. 13D), and the shield frame member 12 that performs electromagnetic shielding is configured.

吸着部材30を取り外し可能とし、吸着箇所をフレーム部材2と分割したことで、フレーム部材2に吸着箇所を設ける必要がなくなるので、フレーム部材2及びシールドフレーム部材12は、低背化が可能となる。なお、特許文献1以前、例えば、特許文献2や特許文献3では、フレーム部材2に吸着箇所を設けるのが一般的であったが、この場合のフレーム部材の高さは電子部品6の厚さとフレーム部材(吸着箇所)の板厚と、電子部品6−吸着箇所間に必要なクリアランスの和になる。これに対し、特許文献1のフレーム部材の高さは電子部品6の厚さと、電子部品6−吸着箇所間に必要なクリアランスと、の和になる。   Since the suction member 30 can be removed and the suction location is divided from the frame member 2, it is not necessary to provide the suction location on the frame member 2. Therefore, the frame member 2 and the shield frame member 12 can be reduced in height. . Prior to Patent Document 1, for example, in Patent Document 2 and Patent Document 3, it was common to provide a suction location on the frame member 2. In this case, the height of the frame member is equal to the thickness of the electronic component 6. This is the sum of the thickness of the frame member (suction part) and the clearance required between the electronic component 6 and the suction part. On the other hand, the height of the frame member of Patent Document 1 is the sum of the thickness of the electronic component 6 and the clearance required between the electronic component 6 and the suction location.

さらに、図13Eに示すように、吸着部材30の天面に段差306を設け、この段差部分を吸着してプリント基板5に搭載すれば、前述した電子部品6−吸着箇所間に必要なクリアランスが吸着部材30側に移行する。これにより、フレーム部材2の高さを更に低背化、具体的にはフレーム内部に搭載される電子部品6の高さと同等に設定することができる。   Further, as shown in FIG. 13E, if a step 306 is provided on the top surface of the suction member 30, and this step portion is sucked and mounted on the printed circuit board 5, a necessary clearance is provided between the electronic component 6 and the suction portion described above. It moves to the adsorption member 30 side. Thereby, the height of the frame member 2 can be further reduced, specifically, set to be equal to the height of the electronic component 6 mounted in the frame.

ここで、一般的に、この吸着部材30は、ステンレスや洋白などの金属の薄板を曲げ加工することにより、所定の形状に成形される。また、吸着部材30とフレーム部材2とは、一方部材の側壁部の所定の位置に設けられた突起と、他方部材の対応箇所に設けられた穴とを嵌合させることにより、保持される。この嵌合部における吸着部材30とフレーム部材2との保持力は、吸着部材30の側壁部の弾性力に大きく依存する。ここで、吸着部材30は金属製であるため、保持力が大きく、容易には外れないようになっている。   Here, in general, the adsorbing member 30 is formed into a predetermined shape by bending a metal thin plate such as stainless steel or white and white. Further, the adsorbing member 30 and the frame member 2 are held by fitting a protrusion provided at a predetermined position on the side wall portion of one member and a hole provided at a corresponding location of the other member. The holding force between the adsorbing member 30 and the frame member 2 in this fitting portion largely depends on the elastic force of the side wall portion of the adsorbing member 30. Here, since the adsorbing member 30 is made of metal, it has a large holding force and does not easily come off.

しかしながら、特許文献1に開示された吸着フレーム部材では、これを用いたプリント基板の製造において、生産性が低いという問題があった。その理由は、プリント基板に吸着フレーム部材を搭載した後、フレーム部材から吸着部材を取り外しづらいためである。より詳細には、吸着部材を取り外す場合、吸着部材の一箇所をハサミなどの切断道具で切断したり、嵌合部をピンセットなどの先が鋭利な取り外し道具でフレーム部材と吸着部材との嵌合面の隙間を広げたりして、取り外す必要がある。この吸着部材は材質が一般的にステンレスや洋白などの金属であるため、切断の際に作業者が相当の荷重を加える必要があった。また、形状によっては吸着部材と他の部品との隙間が狭くなるので切断道具や取り外し道具を所定の位置にセッティングするのが難しかった。   However, the suction frame member disclosed in Patent Document 1 has a problem of low productivity in manufacturing a printed circuit board using the suction frame member. This is because it is difficult to remove the suction member from the frame member after the suction frame member is mounted on the printed circuit board. More specifically, when removing the adsorbing member, cut one part of the adsorbing member with a cutting tool such as scissors, or fit the frame member and the adsorbing member with a sharpening removal tool such as tweezers at the fitting part. It is necessary to remove the gap between the faces. Since this adsorbing member is generally made of a metal such as stainless steel or white, it is necessary for an operator to apply a considerable load during cutting. In addition, depending on the shape, the gap between the suction member and other parts becomes narrow, making it difficult to set the cutting tool and the removal tool at a predetermined position.

本発明の目的は、取り外し可能な吸着部材を容易に取り外すことができ、プリント基板の生産性が向上する吸着フレーム部材を提供することである。   An object of the present invention is to provide a suction frame member that can easily remove a removable suction member and improve the productivity of a printed circuit board.

側壁部22は、天面部21の周縁に沿って天面部21に対し垂直、かつ、吸着部材3を配置しない方向に立ち上がって形成されている。側壁部22は天面部21の周縁全体に沿って設けられているのが好ましいが、一部に開口部などがあっても良い。
突起部23は、側壁部22の外側表面に複数(図2の例では合計12個)配置されている。突起部23は概ね半球体形状が好ましい。
また、フレーム部材2は、ステンレスや洋白などの金属薄板に、曲げ加工、絞り加工、プレス加工などを施すことにより製造することができる。
The top surface portion 21 is provided in a frame shape around the opening 24 having a predetermined shape.
The side wall portion 22 is formed so as to rise along the periphery of the top surface portion 21 in a direction that is perpendicular to the top surface portion 21 and in which the adsorption member 3 is not disposed. The side wall portion 22 is preferably provided along the entire periphery of the top surface portion 21, but may have an opening or the like in part.

The frame member 2 can be manufactured by subjecting a thin metal plate such as stainless steel or white and white to bending, drawing, pressing, or the like.

次に、吸着部材3について図3を用いてより詳細に説明する。図3は、吸着部材3の、その天面の一部を透視した全体斜視図である。図3に示すように、吸着部材3は、天面部301、側壁部302、穴303、天面曲げ部304を備えている。   Next, the adsorption member 3 will be described in more detail with reference to FIG.

天面曲げ部304は、天面部301の輪郭上の側壁部302が形成されていない箇所に、天面部301に対し垂直、かつ側壁部302の立ち上がり方向と反対方向に立ち上がって形成されている。天面曲げ部304は、天面部301の垂直方向からの荷重に対する補強のための部位(補強部)である。また、天面曲げ部304は、吸着部材3をフレーム部材2上に装着した際にフレーム部材2の開口部24上において、配置されていない箇所が複数ある(この箇所を以後非天面曲げ部305とする)。
また、吸着部材3はステンレスや洋白などの金属薄板に、曲げ加工、絞り加工、プレス加工などを施すことにより製造することができる。
The top surface portion 301 is a portion that spreads flatly because it is adsorbed by a suction device. The top surface portion 301 has a shape in which the side wall portion 22 of the frame member 2 is sandwiched and held by the side wall portion 302 across the opening 24 of the frame member 2 when the adsorption member 3 is mounted on the frame member 2. .
The side wall portion 302 is formed at the end of the top surface portion 301 so as to rise in a direction perpendicular to the top surface portion 301 and in contact with the frame member 2. The side wall portion 302 is composed of at least one pair for holding the frame member 2.
A plurality of holes 303 are arranged at positions corresponding to the protrusions 23 of the frame member 2 of the side wall 302. The hole 303 is a part into which the protrusion 23 of the frame member 2 is fitted.
The top surface bent portion 304 is formed to rise in a direction perpendicular to the top surface portion 301 and in a direction opposite to the rising direction of the side wall portion 302 at a location where the side wall portion 302 on the contour of the top surface portion 301 is not formed. The top surface bent portion 304 is a portion (reinforcing portion) for reinforcing the load from the vertical direction of the top surface portion 301. Further, the top surface bending portion 304 has a plurality of places that are not arranged on the opening 24 of the frame member 2 when the adsorption member 3 is mounted on the frame member 2 (hereinafter, this portion is referred to as a non-top surface bending portion). 305).
Further, the adsorbing member 3 can be manufactured by subjecting a thin metal plate such as stainless steel or white and white to bending, drawing, pressing or the like.

次に、フレーム部材2と吸着部材3の着脱に関し、図4A、4Bを用いてより詳細に説明する。図4A、4Bは、図1に示した吸着フレーム部材1の仮想断面Aを矢印方向から見た断面図である。ここで、仮想断面Aは、フレーム部材2の天面部21及び側壁部22と直交し、突起部23を通過する断面である。図4Aはフレーム部材2に吸着部材3が装着された状態の図である。また、図4Bは、フレーム部材2から吸着部材3が離脱された状態の図である。   Next, the attachment / detachment of the frame member 2 and the adsorption member 3 will be described in more detail with reference to FIGS. 4A and 4B. 4A and 4B are cross-sectional views of the virtual cross section A of the suction frame member 1 shown in FIG. Here, the virtual cross section A is a cross section orthogonal to the top surface portion 21 and the side wall portion 22 of the frame member 2 and passing through the projection portion 23. FIG. 4A is a view showing a state in which the adsorption member 3 is attached to the frame member 2. FIG. 4B is a view showing a state where the adsorption member 3 is detached from the frame member 2.

装着時には、フレーム部材2の側壁部22を吸着部材3の側壁部302が挟み込むようになっており、かつ、図4Aに示すようにフレーム部材2の突起部23と吸着部材3の穴303とが嵌合されている。嵌合を外さない限り、吸着部材3はフレーム部材2を保持している。吸着部材3を介して、吸着フレーム部材1を上方へ持ち上げた場合、フレーム部材2の自重により嵌合が外れ、フレーム部材2が落ちることはない。フレーム部材2の突起部23と吸着部材3の穴303とは、吸着部材3の側壁部302を弾性変形で外側に広げた後、吸着部材3をフレーム部材2上に配置し、側壁部302を元に戻すことで容易に嵌合させることができる。また、側壁部302を広げなくとも、吸着部材3をフレーム部材2の上に置き、吸着部材3の天面部301を押し付ければ、吸着部材3の側壁部302がフレーム部材2の突起部23の形状に沿って弾性変形するため嵌合させることができる。   At the time of mounting, the side wall portion 302 of the frame member 2 is sandwiched between the side wall portion 302 of the adsorption member 3, and the projection 23 of the frame member 2 and the hole 303 of the adsorption member 3 are formed as shown in FIG. 4A. It is mated. Unless the fitting is removed, the adsorbing member 3 holds the frame member 2. When the suction frame member 1 is lifted upward through the suction member 3, the frame member 2 does not fall off due to the weight of the frame member 2, and the frame member 2 does not fall. The protrusion 23 of the frame member 2 and the hole 303 of the adsorption member 3 are arranged such that after the side wall portion 302 of the adsorption member 3 is expanded outward by elastic deformation, the adsorption member 3 is arranged on the frame member 2 and the side wall portion 302 is It can be easily fitted by returning to the original state. Even if the side wall portion 302 is not widened, if the suction member 3 is placed on the frame member 2 and the top surface portion 301 of the suction member 3 is pressed, the side wall portion 302 of the suction member 3 becomes the protrusion 23 of the frame member 2. Since it is elastically deformed along the shape, it can be fitted.

離脱時には、図4Bに示すように、吸着部材3の側壁部302を外側に弾性変形で広げると、フレーム部材2の突起部23と吸着部材3の穴303との嵌合が外れ、吸着部材3の保持力が無くなるので、吸着部材3は容易に外れる。ここで、嵌合を外せば破損することなく、吸着部材3を外すことができる。また、吸着部材3の側壁部302を広げなくとも、フレーム部材2の側壁部22に沿って、上方向に大きな荷重(フレーム部材2の自重の数倍以上)を加えても、吸着部材3は側壁部302がフレーム部材2の突起部23の形状に沿って広がり、フレーム部材2の突起部23と吸着部材3の穴303との嵌合は外れる場合がある。   At the time of detachment, as shown in FIG. 4B, when the side wall portion 302 of the adsorption member 3 is expanded outward by elastic deformation, the projection 23 of the frame member 2 and the hole 303 of the adsorption member 3 are disengaged, and the adsorption member 3 Therefore, the adsorbing member 3 can be easily removed. Here, if the fitting is removed, the adsorbing member 3 can be removed without being damaged. Even if the side wall 302 of the adsorbing member 3 is not widened, the adsorbing member 3 is not affected by applying a large upward load (several times the weight of the frame member 2 or more) along the side wall 22 of the frame 2. The side wall portion 302 extends along the shape of the protrusion 23 of the frame member 2, and the fitting between the protrusion 23 of the frame member 2 and the hole 303 of the suction member 3 may be released.

次に、本発明における吸着フレーム部材1を用いて構成されるシールドフレーム部材とこのシールドフレーム部材に用いられるカバー部材を、図5A、図5Bを用いて説明する。図5Aは、本実施の形態に係る吸着フレーム部材を用いて構成するシールドフレーム部材の全体斜視図である。また、図5Bは、シールドフレーム部材に用いられるカバー部材を示す斜視図である。   Next, a shield frame member configured using the suction frame member 1 according to the present invention and a cover member used for the shield frame member will be described with reference to FIGS. 5A and 5B. FIG. 5A is an overall perspective view of a shield frame member configured using the suction frame member according to the present embodiment. FIG. 5B is a perspective view showing a cover member used for the shield frame member.

図5Aに示すように、シールドフレーム部材10は、吸着部材3が取り外されたフレーム部材2と、これを覆う着脱可能なカバー部材4とから構成されている。   As shown in FIG. 5A, the shield frame member 10 includes a frame member 2 from which the adsorbing member 3 is removed, and a detachable cover member 4 that covers the frame member 2.

図5Bに示すように、カバー部材4は、天面部41、側壁部42、穴43を備えている。
平坦に広がる天面部41の輪郭は、フレーム部材2の平面方向の輪郭と同等もしくは若干大きい形状・サイズとなっており、カバー部材4の側壁部42でフレーム部材2の側壁部22を挟み込むようになっている。
側壁部42は、フレーム部材2と連結するための部位であり、天面部41の輪郭に沿って、天面部41に対し垂直、かつフレーム部材2と接触する方向に立ち上がって形成されている。
穴43は、側壁部42に複数配置された、フレーム部材2の突起部23が嵌る部位である。穴43はカバー部材4をフレーム部材2上に装着した際にフレーム部材2の突起部23の位置に対応する位置に配置される。
また、カバー部材4はステンレスや洋白などの金属薄板に曲げ加工や絞り加工、プレス加工などを施すことにより製造することができる。
As shown in FIG. 5B, the cover member 4 includes a top surface portion 41, a side wall portion 42, and a hole 43.
The contour of the top surface portion 41 that spreads flatly has a shape or size that is equal to or slightly larger than the contour of the frame member 2 in the plane direction, and the side wall portion 22 of the frame member 2 is sandwiched between the side wall portions 42 of the cover member 4. It has become.
The side wall part 42 is a part for connecting to the frame member 2, and is formed to rise in a direction perpendicular to the top surface part 41 and in contact with the frame member 2 along the outline of the top surface part 41.
A plurality of holes 43 are portions that are arranged in the side wall portion 42 and into which the protruding portions 23 of the frame member 2 are fitted. The hole 43 is disposed at a position corresponding to the position of the protrusion 23 of the frame member 2 when the cover member 4 is mounted on the frame member 2.
Further, the cover member 4 can be manufactured by subjecting a thin metal plate such as stainless steel or white and white to bending, drawing, pressing or the like.

フレーム部材2とカバー部材4の着脱に関しては、上記した吸着部材3と同様であり、フレーム部材2の突起部23とカバー部材4の穴43との嵌合が保たれている場合は、容易に外れることがない。また、嵌合を外しさえすれば、破損することなくカバー部材4を離脱することができる。また、フレーム部材2とカバー部材4は金属であり、フレーム部材2の突起部23とカバー部材4の穴43との嵌合により、フレーム部材2とカバー部材4は安定な接触がなされる。そのため、フレーム部材2とカバー部材4とは安定的に電気接続されていることになる。   The attachment and detachment of the frame member 2 and the cover member 4 are the same as those of the adsorption member 3 described above, and when the fitting between the projection 23 of the frame member 2 and the hole 43 of the cover member 4 is maintained, it is easy. It will not come off. Further, as long as the fitting is removed, the cover member 4 can be detached without being damaged. Further, the frame member 2 and the cover member 4 are made of metal, and the frame member 2 and the cover member 4 are brought into stable contact with each other by fitting between the projection 23 of the frame member 2 and the hole 43 of the cover member 4. Therefore, the frame member 2 and the cover member 4 are stably electrically connected.

なお、上記の説明では、フレーム部材2の側壁部22の外側表面に突起を、吸着部材3の側壁部302及びカバー部材4の側壁部42に穴を設けた。しかしながら、逆に、フレーム部材2の側壁部22に穴を、吸着部材3の側壁部302の内側表面及びカバー部材4の側壁部42の内側表面に突起を設けてもよい。フレーム部材2へ吸着部材3及びカバー部材4を同様に着脱することが可能である。   In the above description, protrusions are provided on the outer surface of the side wall portion 22 of the frame member 2, and holes are provided in the side wall portion 302 of the adsorption member 3 and the side wall portion 42 of the cover member 4. However, conversely, a hole may be provided in the side wall portion 22 of the frame member 2, and a protrusion may be provided on the inner surface of the side wall portion 302 of the adsorption member 3 and the inner surface of the side wall portion 42 of the cover member 4. The adsorption member 3 and the cover member 4 can be similarly attached to and detached from the frame member 2.

以上詳細に実施の形態の構成を述べたが、曲げ加工、プレス加工などの各部材を所定の形状にする加工工程は、当業者にとってよく知られており、また本発明とは直接関係しないので、その詳細な構成は省略する。   Although the configuration of the embodiment has been described in detail above, the processing steps for forming each member into a predetermined shape such as bending and pressing are well known to those skilled in the art and are not directly related to the present invention. The detailed configuration is omitted.

次に、吸着フレーム部材1からシールドフレーム部材10を構成する方法を、図6を用いて説明する。図6A〜6Fは、本発明における吸着フレーム部材1をプリント基板5上に搭載した後、シールドフレーム部材10を構成するまでの一連の流れを示す図である。図6Aは吸着フレーム部材1を搭載した直後のプリント基板5の全体斜視図である。図6Bは図6Aの構成の説明に用いた際の仮想断面A(図1参照)における断面図である。図6Cは、吸着フレーム部材1を搭載する時の仮想断面Aにおける断面図である。図6Dはフレーム部材2から吸着部材3を取り外す時の仮想断面Aにおける断面図である。図6Eは吸着部材3を取り外した後、フレーム部材2にカバー部材4を装着してシールドフレーム部材10を構成した時の全体斜視図である。図6Fは図6Eの仮想断面Aにおける断面図である。   Next, a method for constructing the shield frame member 10 from the suction frame member 1 will be described with reference to FIG. FIGS. 6A to 6F are diagrams showing a series of flows until the shield frame member 10 is configured after the suction frame member 1 according to the present invention is mounted on the printed circuit board 5. FIG. 6A is an overall perspective view of the printed circuit board 5 immediately after mounting the suction frame member 1. 6B is a cross-sectional view taken along a virtual cross section A (see FIG. 1) when used to explain the configuration of FIG. 6A. FIG. 6C is a cross-sectional view of the virtual cross section A when the suction frame member 1 is mounted. FIG. 6D is a cross-sectional view of the virtual cross section A when the adsorption member 3 is removed from the frame member 2. FIG. 6E is an overall perspective view of the shield frame member 10 configured by attaching the cover member 4 to the frame member 2 after removing the adsorption member 3. 6F is a cross-sectional view taken along a virtual cross section A in FIG. 6E.

図6A、図6Bに示すように、吸着フレーム部材1では、フレーム部材2の側壁部22の端部が、プリント基板5のパッド51上に半田付けされている。パッド51は、プリント基板5の所定の位置に設けられ、プリント基板5のGNDと電気的に接続されている。更に、プリント基板5上のフレーム部材2の内部にはボールグリッドアレイ(BGA)などの電子部品6が配置されている。フレーム部材2の高さは、プリント基板5上に配置した際に、電子部品6の表面のプリント基板5表面からの高さと、後述する電子部品6の天面と吸着部材3の天面部301の裏に必要なクリアランスの値との和となるよう設定されている。   As shown in FIGS. 6A and 6B, in the suction frame member 1, the end portion of the side wall portion 22 of the frame member 2 is soldered onto the pad 51 of the printed circuit board 5. The pad 51 is provided at a predetermined position on the printed circuit board 5 and is electrically connected to the GND of the printed circuit board 5. Furthermore, an electronic component 6 such as a ball grid array (BGA) is disposed inside the frame member 2 on the printed circuit board 5. When the frame member 2 is arranged on the printed circuit board 5, the height of the surface of the electronic component 6 from the surface of the printed circuit board 5, the top surface of the electronic component 6, which will be described later, and the top surface portion 301 of the suction member 3 are arranged. It is set to be the sum of the necessary clearance values on the back.

次に、吸着フレーム部材1の搭載工程について説明する。図6Cに示すように、最初に吸着部材3の天面部301の吸着部を吸着ヘッド7により吸引し、吸着フレーム部材1を保持する。次に、吸着フレーム部材1を吸着ヘッド7により保持したまま、プリント基板5上の所定の位置(フレーム部材2の側壁部22がプリント基板5のパッド51上となる位置)まで移動する。そして、吸着ヘッド7をプリント基板5の方向(図6Cの矢印方向)に降ろすことで、フレーム部材2の側壁部22の端部とプリント基板5のパッド51上に印刷された半田ペースト(不図示)とを接触させる。その後、吸着ヘッド7による吸引を解除する。最後に、吸着フレーム部材1を搭載したプリント基板5を、リフロー工程に流すことで、半田ペーストが溶融し、フレーム部材2とプリント基板5のGNDとが機械的及び電気的に安定して接続される。ここで、電子部品6の機械的及び電気的接続も同時に行われる。   Next, the mounting process of the suction frame member 1 will be described. As shown in FIG. 6C, the suction portion of the top surface portion 301 of the suction member 3 is first sucked by the suction head 7 to hold the suction frame member 1. Next, while the suction frame member 1 is held by the suction head 7, the suction frame member 1 is moved to a predetermined position on the printed circuit board 5 (position where the side wall portion 22 of the frame member 2 is on the pad 51 of the printed circuit board 5). And the solder paste (not shown) printed on the edge part of the side wall part 22 of the frame member 2 and the pad 51 of the printed circuit board 5 by lowering the suction head 7 in the direction of the printed circuit board 5 (arrow direction in FIG. 6C). ). Thereafter, suction by the suction head 7 is released. Finally, by flowing the printed circuit board 5 on which the suction frame member 1 is mounted in the reflow process, the solder paste is melted, and the frame member 2 and the GND of the printed circuit board 5 are stably connected mechanically and electrically. The Here, mechanical and electrical connection of the electronic component 6 is also performed at the same time.

次に、吸着部材3の取り外し方法について図6Dを用いて説明する。図6Dは、吸着フレーム部材1をプリント基板5に搭載後、吸着部材3をフレーム部材2から取り外す時の、仮想断面A(上記参照)における断面図である。   Next, a method for removing the adsorption member 3 will be described with reference to FIG. 6D. FIG. 6D is a cross-sectional view of the virtual cross section A (see above) when the suction member 3 is removed from the frame member 2 after the suction frame member 1 is mounted on the printed circuit board 5.

図6B、図6Dに示すように、吸着部材3の天面部301のフレーム部材2の開口部24上の箇所をプリント基板5方向に押し付ける。このとき、フレーム部材2の開口部24上に設けられた天面部301には、補強用の天面曲げ部304が設けられていない非天面曲げ部305が2箇所設けられている。非天面曲げ部305を配置した箇所は天面曲げ部304を配置した箇所に対して天面部301の垂直方向に対する剛性(断面2次モーメント)が低いため、この非天面曲げ部305を配置した箇所(屈曲部)が屈曲し、押した箇所が沈み込む。そして、この屈曲部を力点、フレーム部材2の天面部21の内側の縁211を支点、フレーム部材2の突起部23と吸着部材3の穴303との嵌合部を作用点として、てこの原理が働く。そのため、フレーム部材2の側壁部22には、図6Dの矢印方向の(嵌合を外す方向に働く)モーメントが加えられる。ここで、天面部301を所定量押し込むことで、吸着部材3は、フレーム部材2の突起部23と側壁部302の穴303の嵌合が外れ、側壁部302が上方向に移動し、フレーム部材2から取り外される。   As shown in FIG. 6B and FIG. 6D, the location on the opening 24 of the frame member 2 of the top surface 301 of the suction member 3 is pressed toward the printed circuit board 5. At this time, the top surface portion 301 provided on the opening 24 of the frame member 2 is provided with two non-top surface bending portions 305 that are not provided with the reinforcing top surface bending portion 304. The location where the non-top surface bending portion 305 is arranged is lower in rigidity (second moment of section) in the vertical direction of the top surface portion 301 than the location where the top surface bending portion 304 is arranged. The bent part (bent part) bends and the pressed part sinks. Then, the principle of the lever is made with the bent portion as a force point, the inner edge 211 of the top surface portion 21 of the frame member 2 as a fulcrum, and the fitting portion between the projection 23 of the frame member 2 and the hole 303 of the suction member 3 as the action point. Work. Therefore, a moment is applied to the side wall portion 22 of the frame member 2 in the direction of the arrow in FIG. Here, by pushing the top surface portion 301 by a predetermined amount, the adsorption member 3 is disengaged from the projections 23 of the frame member 2 and the holes 303 of the side wall portion 302, and the side wall portion 302 moves upward, and the frame member Removed from 2.

つまり、本発明に係る吸着フレーム部材1では、吸着部材3の天面部301に、その垂直方向に対する剛性が高い箇所(天面曲げ部304を配置した箇所:非屈曲部)とフレーム部材2の開口部24上に剛性が低い箇所(非天面曲げ部305を配置した箇所:屈曲部)とが設けられている。ここで、フレーム部材2の開口部24上に位置する天面部301を押すと、剛性が低い箇所のみが屈曲し、更にこの屈曲部を力点、フレーム部材2の天面部21の内側の縁211を支点、フレーム部材2の突起部23と吸着部材3の穴303との嵌合部を作用点として、てこの原理が働く。これにより、フレーム部材2の突起部23と吸着部材3の穴303との嵌合を外し、吸着部材3をフレーム部材2から取り外している。   That is, in the suction frame member 1 according to the present invention, the top surface portion 301 of the suction member 3 has a portion with high rigidity in the vertical direction (a portion where the top surface bent portion 304 is disposed: an unbent portion) and the opening of the frame member 2. On the portion 24, a portion having low rigidity (a portion where the non-top surface bent portion 305 is disposed: a bent portion) is provided. Here, when the top surface portion 301 located on the opening 24 of the frame member 2 is pressed, only a portion having low rigidity is bent. Further, this bent portion is used as a power point, and the inner edge 211 of the top surface portion 21 of the frame member 2 is bent. The lever principle works with a fulcrum, a fitting portion between the projection 23 of the frame member 2 and the hole 303 of the suction member 3 as an action point. Thereby, the fitting between the projection 23 of the frame member 2 and the hole 303 of the suction member 3 is removed, and the suction member 3 is removed from the frame member 2.

ここで、吸着部材3の天面部301を押し込んだ際、天面部301が電子部品6の天面と接触しないように、フレーム部材2の高さは設定されている。   Here, the height of the frame member 2 is set so that the top surface portion 301 does not come into contact with the top surface of the electronic component 6 when the top surface portion 301 of the suction member 3 is pushed.

また、天面部301の剛性に関して、若干補足する。天面部301は、押し込んだ際に、例えば、天面部301の天面曲げ部304を配置した箇所の応力は吸着部材3の材料の降伏応力値以下となっている。また、天面部301の非天面曲げ部305にあたる箇所の応力は吸着部材3の材料の降伏応力値以上となるように断面2次モーメントが設定されている。一般的に、曲げた際の応力Pは、断面2次モーメントI、押し込んだ際の曲げモーメントMにより、P=M/Iで表される。天面部301の天面曲げ部304を配置した箇所は、天面曲げ部304を配置しているため、非天面曲げ部305を配置した箇所に比べ、断面2次モーメントIが高い。曲げモーメントMは荷重と、荷重からの距離などに依存し、上記のような関係となるように、非天面曲げ部305は配置されている。   Further, the rigidity of the top surface portion 301 will be supplemented slightly. When the top surface portion 301 is pushed in, for example, the stress at the location where the top surface bending portion 304 of the top surface portion 301 is disposed is equal to or less than the yield stress value of the material of the adsorption member 3. Further, the secondary moment of the cross section is set so that the stress at the portion corresponding to the non-top surface bending portion 305 of the top surface portion 301 is equal to or higher than the yield stress value of the material of the adsorption member 3. Generally, the stress P at the time of bending is expressed by P = M / I by the secondary moment I of the cross section and the bending moment M at the time of pushing. Since the top surface bent portion 304 of the top surface portion 301 is disposed, since the top surface bent portion 304 is disposed, the cross-sectional secondary moment I is higher than the portion where the non-top surface bent portion 305 is disposed. The non-top surface bending portion 305 is arranged so that the bending moment M depends on the load, the distance from the load, and the like and has the above relationship.

吸着部材3を取り外した後、図6Eに示すように、フレーム部材2にカバー部材4を取り付け、シールドフレーム部材10を構成する。このとき、電子部品6は、図6Fに示すように、プリント基板5のGNDと電気的に接続され、金属からなるフレーム部材2とカバー部材4により周囲を覆われることになる。そのため、電子部品6は、シールドフレーム部材10の外部と電磁的に遮蔽される。   After removing the adsorbing member 3, as shown in FIG. 6E, the cover member 4 is attached to the frame member 2 to form the shield frame member 10. At this time, as shown in FIG. 6F, the electronic component 6 is electrically connected to the GND of the printed circuit board 5, and the periphery is covered by the frame member 2 and the cover member 4 made of metal. Therefore, the electronic component 6 is electromagnetically shielded from the outside of the shield frame member 10.

上記説明において、吸着部材3の天面部301の輪郭をフレーム部材2の対向する2つの側壁部22のみを保持するようにした。しかしながら、これ以外にも、吸着部材3が少なくともフレーム部材2の互いに対向する側壁部22を保持することができればよい。例えば、天面部301の輪郭を十字形状にしたり、Y字形状にしたり、フレーム部材2の天面部21の全てを覆うようしたりしてもよい。   In the above description, only the two opposing side wall portions 22 of the frame member 2 are held in the outline of the top surface portion 301 of the adsorption member 3. However, other than this, it is only necessary that the adsorbing member 3 can hold at least the side wall portions 22 of the frame member 2 facing each other. For example, the outline of the top surface portion 301 may be a cross shape, a Y shape, or the top surface portion 21 of the frame member 2 may be covered.

(第2の実施の形態)
次に本発明の第2の実施の形態について図7A〜9Cを参照して詳細に説明する。
本発明の第2の実施の形態は、その基本構成・概念は第1の実施の形態と同様あるが、吸着部材に剛性の高い箇所、低い箇所を設けるにあたり、形状、材料、処理などに第1の実施の形態とは異なる工夫がなされている。なお、フレーム部材の構成や、吸着部材のフレーム部材への取り付け、プリント基板への搭載方法等は第1の実施の形態と同様であるため、重複する説明は割愛する。
(Second Embodiment)
Next, a second embodiment of the present invention will be described in detail with reference to FIGS.
In the second embodiment of the present invention, the basic configuration and concept are the same as those in the first embodiment, but the shape, material, processing, etc. are different in providing a highly rigid portion and a low portion on the adsorption member. The device is different from the first embodiment. The configuration of the frame member, the attachment of the adsorption member to the frame member, the mounting method on the printed circuit board, and the like are the same as those in the first embodiment, and therefore redundant description is omitted.

図7A〜7Cには、第1の実施の形態とは異なる形状の工夫により、吸着部材の天面部に剛性差を設けた吸着フレーム部材1が示されている。図7Aは、吸着部材31をフレーム部材2に装着した状態の吸着フレーム部材1の全体斜視図である。図7Bは、プリント基板5に搭載後の第1の実施の形態に係る仮想断面Aと同様の断面における断面図である。また、図7Cは、図7Bの状態から吸着部材31をフレーム部材2から取り外す場合の断面図である。   7A to 7C show the suction frame member 1 in which a difference in rigidity is provided on the top surface portion of the suction member by a device having a shape different from that of the first embodiment. FIG. 7A is an overall perspective view of the suction frame member 1 in a state where the suction member 31 is attached to the frame member 2. FIG. 7B is a cross-sectional view in the same cross section as the virtual cross section A according to the first embodiment after being mounted on the printed circuit board 5. FIG. 7C is a cross-sectional view when the adsorption member 31 is removed from the frame member 2 from the state of FIG. 7B.

図7A、図7Bに示すように、吸着フレーム部材1の吸着部材31は、第1の実施の形態と同様に、天面部311と側壁部312とで構成されている。更に、フレーム部材2の開口部24上に位置する天面部311の表面には、2本の溝部315が側壁部312と概ね平行となるように形成されている。ここで、溝部315は、天面部311のその他の箇所に比べ、薄肉となっているので、天面部311の垂直方向に対する剛性(断面2次モーメント)が低くい。そのため、図7Cに示すように、フレーム部材2の開口部24上に位置する天面部311を押すと、溝部315が屈曲し、第1の実施の形態と同様の原理に基づき、吸着部材31がフレーム部材2から外れる。   As shown in FIGS. 7A and 7B, the suction member 31 of the suction frame member 1 includes a top surface portion 311 and a side wall portion 312 as in the first embodiment. Furthermore, two groove portions 315 are formed on the surface of the top surface portion 311 located on the opening 24 of the frame member 2 so as to be substantially parallel to the side wall portion 312. Here, since the groove part 315 is thin compared with the other location of the top | upper surface part 311, the rigidity (cross-sectional secondary moment) with respect to the perpendicular | vertical direction of the top | upper surface part 311 is low. Therefore, as shown in FIG. 7C, when the top surface portion 311 located on the opening 24 of the frame member 2 is pushed, the groove portion 315 is bent, and the adsorption member 31 is formed based on the same principle as in the first embodiment. The frame member 2 is detached.

図8A〜8Cには、第1の実施の形態とは異なる材料の工夫により、吸着部材の天面部に剛性差を設けた吸着フレーム部材1が示されている。図8Aは、吸着部材32をフレーム部材2に装着した状態の吸着フレーム部材1の全体斜視図である。図8Bは、図7と同様の断面図である。また、図8Cは、図8Bの状態から吸着部材32をフレーム部材2から取り外す場合の断面図である。   8A to 8C show a suction frame member 1 in which a difference in rigidity is provided on the top surface portion of the suction member by devising a material different from that of the first embodiment. FIG. 8A is an overall perspective view of the suction frame member 1 in a state where the suction member 32 is mounted on the frame member 2. FIG. 8B is a cross-sectional view similar to FIG. FIG. 8C is a cross-sectional view when the adsorption member 32 is removed from the frame member 2 from the state of FIG. 8B.

図8A、図8Bにおいて、吸着フレーム部材1の吸着部材32は第1の実施の形態と同様に天面部321と側壁部322とで構成されている。更に、天面部321は、金属部324を樹脂部325により連結され、構成される。2本の樹脂部325は、側壁部322と概ね平行となるように形成されている。樹脂部325は材料の特性上、金属部324に比べ、剛性(ヤング率)が低くい。そのため、図8Cに示すように、フレーム部材2の開口部24上に位置する金属部324を押すと樹脂部325が屈曲し、第1の実施の形態と同様の原理に基づき、吸着部材32がフレーム部材2から外れる。なお、吸着部材32は、金属部324にインサート成形などにより樹脂部325を形成することにより、実現される。   8A and 8B, the suction member 32 of the suction frame member 1 is composed of a top surface portion 321 and a side wall portion 322 as in the first embodiment. Furthermore, the top surface portion 321 is configured by connecting the metal portion 324 with the resin portion 325. The two resin parts 325 are formed so as to be substantially parallel to the side wall part 322. The resin part 325 has lower rigidity (Young's modulus) than the metal part 324 due to the characteristics of the material. Therefore, as shown in FIG. 8C, when the metal portion 324 located on the opening 24 of the frame member 2 is pressed, the resin portion 325 is bent, and the adsorbing member 32 is formed based on the same principle as in the first embodiment. The frame member 2 is detached. The adsorption member 32 is realized by forming the resin portion 325 on the metal portion 324 by insert molding or the like.

図9A〜9Cには、第1の実施の形態とは異なる処理の工夫により、吸着部材の天面部に剛性差を設けた吸着フレーム部材1が示されている。図9Aは吸着部材33をフレーム部材2に装着した状態の吸着フレーム部材1の全体斜視図である。図9Bは図7と同様の断面図である。図9Cは図9Bの状態から吸着部材33をフレーム部材2から取り外す場合の断面図である。   FIGS. 9A to 9C show the suction frame member 1 in which a difference in rigidity is provided on the top surface portion of the suction member by devising a process different from that of the first embodiment. FIG. 9A is an overall perspective view of the suction frame member 1 with the suction member 33 mounted on the frame member 2. FIG. 9B is a cross-sectional view similar to FIG. FIG. 9C is a cross-sectional view of the suction member 33 being removed from the frame member 2 from the state of FIG. 9B.

図9A、図9Bに示すように、吸着フレーム部材1の吸着部材33は第1の実施の形態と同様に天面部331と側壁部332とで構成されている。更に、天面部331には窒化処理などの硬化処理が施された硬化処理部334と、前記の硬化処理を施さない非硬化処理部335とが形成されている。2本の非硬化処理部335は側壁部332と概ね平行となるように形成されている。非硬化処理部335は、硬化処理部334に比べ、天面部311の垂直方向に対する剛性が低くい。そのため、図9Cに示すように、フレーム部材2の開口部24上に位置する硬化処理部334を押すと非硬化処理部335が変形し、第1の実施の形態と同様の原理に基づき、吸着部材33はフレーム部材2から外れる。硬化処理の手法は当事者によく知られており、その詳細な説明は省略する。   As shown in FIGS. 9A and 9B, the suction member 33 of the suction frame member 1 includes a top surface portion 331 and a side wall portion 332, as in the first embodiment. Further, the top surface portion 331 is formed with a curing processing unit 334 that has been subjected to a curing process such as a nitriding process, and a non-curing process unit 335 that is not subjected to the curing process. The two non-curing treatment parts 335 are formed so as to be substantially parallel to the side wall part 332. The non-curing processing unit 335 is less rigid in the vertical direction of the top surface 311 than the curing processing unit 334. Therefore, as shown in FIG. 9C, when the curing processing unit 334 located on the opening 24 of the frame member 2 is pressed, the non-curing processing unit 335 is deformed, and the adsorption is performed based on the same principle as in the first embodiment. The member 33 is detached from the frame member 2. The method of the curing process is well known to those skilled in the art and will not be described in detail.

(第3の実施の形態)
次に本発明の第3の実施の形態について、図10を用いて説明する。本発明の第3の実施の形態は、その基本的構成・概念は第1の実施の形態の通りである。他方、フレーム部材に、吸着フレーム部材の高さをより低くするための工夫がなされている。なお、吸着部材の基本構成、吸着部材のフレーム部材への取り付けや、プリント基板への搭載方法等は第1の実施の形態と同様であるため、重複する説明は割愛する。
(Third embodiment)
Next, a third embodiment of the present invention will be described with reference to FIG. The basic configuration and concept of the third embodiment of the present invention is the same as that of the first embodiment. On the other hand, the frame member is devised to lower the height of the suction frame member. Note that the basic configuration of the suction member, the attachment of the suction member to the frame member, the mounting method on the printed circuit board, and the like are the same as those in the first embodiment, and therefore redundant description is omitted.

図10A、10Bには、本発明の第3の実施の形態に係る吸着フレーム部材1が示されている。図10Aは、吸着部材3をフレーム部材20に装着した状態の吸着フレーム部材1の、吸着部材3の天面の一部を透視した全体斜視図である。図10Bは、プリント基板搭載後、吸着部材3をフレーム部材20から取り外す時の断面図(断面は図8と同様)である。   10A and 10B show a suction frame member 1 according to a third embodiment of the present invention. FIG. 10A is an overall perspective view of a portion of the top surface of the suction member 3 of the suction frame member 1 with the suction member 3 attached to the frame member 20. FIG. 10B is a cross-sectional view when the suction member 3 is removed from the frame member 20 after mounting the printed circuit board (the cross-section is the same as FIG. 8).

図10Aに示すように、吸着フレーム部材1は、フレーム部材20と、その上に着脱可能に配置された吸着部材3とを備えている。フレーム部材20は、第1の実施の形態と同様に、天面部201と側壁部202と突起部とを備えている。更に、フレーム部材20の天面部201の開口部204には2つの梁部205が概ね平行に、かつ、フレーム部材20の内部に配置される電子部品6を介して対向して配置されている。吸着部材3は第1の実施の形態と同様のものである。フレーム部材20の梁部205の内側の開口部204a上において、非天面曲げ部305が梁部205と概ね平行に配置されている。   As shown in FIG. 10A, the suction frame member 1 includes a frame member 20 and a suction member 3 that is detachably disposed thereon. As in the first embodiment, the frame member 20 includes a top surface portion 201, a side wall portion 202, and a protruding portion. Further, the two beam portions 205 are disposed in parallel to the opening 204 of the top surface portion 201 of the frame member 20 so as to face each other with the electronic component 6 disposed inside the frame member 20 interposed therebetween. The adsorbing member 3 is the same as that in the first embodiment. On the opening 204 a inside the beam portion 205 of the frame member 20, the non-top surface bent portion 305 is disposed substantially parallel to the beam portion 205.

ここで、図10Bに示すように、フレーム部材20の梁部205の内部の開口部204a上に位置する吸着部材3の天面部301を押し込むと、第1の実施の形態と同様に、天面部301の非天面曲げ部305を配置した箇所が屈曲しながら、天面部301が沈み込む。このとき、屈曲した箇所を力点、梁部205の内側縁2051を支点、フレーム部材20の突起部と吸着部材3の穴の嵌合部を作用点として、てこの原理が働く。吸着部材3は、第1の実施の形態と同様に、側壁部302が上方向に移動し、フレーム部材20から取り外される。   Here, as shown in FIG. 10B, when the top surface portion 301 of the adsorption member 3 located on the opening 204a inside the beam portion 205 of the frame member 20 is pushed in, the top surface portion is the same as in the first embodiment. While the portion where the non-top surface bending portion 305 of 301 is disposed is bent, the top surface portion 301 sinks. At this time, the lever principle works by using the bent portion as a force point, the inner edge 2051 of the beam portion 205 as a fulcrum, and the fitting portion between the projection portion of the frame member 20 and the hole of the adsorption member 3 as an action point. As in the first embodiment, the suction member 3 is removed from the frame member 20 as the side wall portion 302 moves upward.

第3の実施の形態では、第1の実施の形態に比べ、支点と力点の間の距離が短くなるので、てこの原理から、吸着部材3の側壁部302を外すのに必要な天面部301の押し込み量を小さくすることができる。側壁部302を完全に外すにあたり、側壁部302の端部をフレーム部材の突起の端部まで上げなければならない。てこの原理から、力点の支点からの距離をa、作用点の支点からの距離をb、力点の変位量をc、作用点の変位量をdとするとd=c×b/aが成り立ち、所定のdを作り出す際にaが小さく、dが大きくなれば、cは小さくなる。そのため、天面部301を押し込みのために必要な天面部301と電子部品6との間のクリアランスを第1の実施の形態に比べ、狭くすることができる。従って、フレーム部材の高さ、強いてはこれを用いたシールドフレーム部材の高さを低くすることができる。   In the third embodiment, since the distance between the fulcrum and the force point is shorter than in the first embodiment, the top surface portion 301 necessary for removing the side wall portion 302 of the attracting member 3 from the lever principle. The pushing amount of can be reduced. In order to completely remove the side wall 302, the end of the side wall 302 must be raised to the end of the projection of the frame member. From the lever principle, if the distance from the fulcrum of the force point is a, the distance from the fulcrum of the action point is b, the displacement of the force point is c, and the displacement of the action point is d, d = c × b / a holds. When a predetermined d is produced, if a is small and d is large, c is small. Therefore, the clearance between the top surface portion 301 and the electronic component 6 necessary for pushing the top surface portion 301 can be made narrower than in the first embodiment. Accordingly, the height of the frame member, and hence the height of the shield frame member using the frame member can be lowered.

(第4の実施の形態)
次に本発明の第4の実施の形態について、図11を用いて説明する。本発明の第4の実施の形態は、その基本的構成・概念は第1の実施の形態の通りである。他方、吸着部材に、フレーム部材の高さをより低くするための工夫がなされている。なお、フレーム部材の構成、吸着部材のフレーム部材への取り付け、プリント基板への搭載方法等は第1の実施の形態と同様であるため、重複する説明は割愛する。
(Fourth embodiment)
Next, a fourth embodiment of the present invention will be described with reference to FIG. The basic configuration and concept of the fourth embodiment of the present invention is the same as that of the first embodiment. On the other hand, the adsorbing member is devised to lower the height of the frame member. The configuration of the frame member, the attachment of the suction member to the frame member, the mounting method on the printed circuit board, and the like are the same as those in the first embodiment, and thus redundant description is omitted.

FIG. 11A is an overall perspective view of the suction frame member 1. FIG. 11B is an overall perspective view of the adsorption member 34 used in the adsorption frame member 1 as seen through a part of its top surface. FIG. 11C is an overall perspective view of the printed circuit board 5 immediately after the adsorption member 34 is mounted. FIG. 11D is a cross-sectional view when the adsorption member 34 is mounted (the cross-section is the same as FIG. 8). FIG. 11E is a cross-sectional view when the adsorption member 34 is removed from the frame member 2 after being mounted on the printed board 5 (the cross-section is the same as FIG. 8). FIG. 11F is a cross-sectional view of the shield frame member 10 when the cover member 4 is attached to the frame member 2 after the adsorption member 34 is removed (the cross-section is the same as FIG. 8).

図11Aに示すように、吸着フレーム部材1は、フレーム部材2と、その上に着脱可能に配置された吸着部材34とを備えている。
図11Bに示すように、吸着部材34は、平坦な面をもつ天面部341、側壁部342、穴343、天面曲げ部344を備えている。
側壁部342は、天面部341の端部に、天面部341に対し垂直、かつフレーム部材2と接触する方向に立ち上がって形成されている。側壁部342は、フレーム部材2との保持を行うための少なくとも1対からなる。
穴343は、側壁部342のフレーム部材2の突起部23に対応した位置に複数配置されている。
更に天面部341には、天面曲げ部344、曲げ根元部345、段差部346が形成されている。
天面曲げ部344は、天面部341の輪郭上の側壁部342及び曲げ根元部345以外の箇所に天面部341に対し垂直、かつ側壁部342の立ち上がり方向とは反対の方向に立ち上がって形成されている。天面曲げ部344は、天面部341の垂直方向からの荷重に対する補強のための部位である。
曲げ根元部345は、段差部346を形成するために曲げられた部位である。曲げ根元部345は、フレーム部材2の開口部24上、かつプリント基板に搭載する電子部品6の外側に配置される。
段差部346は、天面部341の中央部において一段高く形成された部位である。
As shown in FIG. 11A, the suction frame member 1 includes a frame member 2 and a suction member 34 that is detachably disposed thereon.
As shown in FIG. 11B, the adsorbing member 34 includes a top surface portion 341 having a flat surface, a side wall portion 342, a hole 343, and a top surface bending portion 344.
The side wall portion 342 is formed at the end of the top surface portion 341 so as to rise in a direction perpendicular to the top surface portion 341 and in contact with the frame member 2. The side wall part 342 includes at least one pair for holding the frame member 2.
A plurality of holes 343 are arranged at positions corresponding to the protrusions 23 of the frame member 2 of the side wall 342.
Further, the top surface portion 341 is formed with a top surface bending portion 344, a bending root portion 345, and a step portion 346.
The top surface bent portion 344 is formed to rise in a direction perpendicular to the top surface portion 341 at a position other than the side wall portion 342 and the bending root portion 345 on the contour of the top surface portion 341 and in a direction opposite to the rising direction of the side wall portion 342. ing. The top surface bent portion 344 is a portion for reinforcing the load from the vertical direction of the top surface portion 341.
The bent root portion 345 is a portion bent to form the stepped portion 346. The bending root portion 345 is disposed on the opening 24 of the frame member 2 and outside the electronic component 6 mounted on the printed circuit board.
The step portion 346 is a portion formed one step higher in the central portion of the top surface portion 341.

次に、第4の実施の形態に係る吸着フレーム部材1をプリント基板5へ搭載する方法を説明する。図11Dに示すように、最初に吸着部材34の段差部346の天面を吸着ヘッド7により吸引し、吸着フレーム部材1を保持する。次に、第1の実施の形態と同様に、吸着フレーム部材1をプリント基板5上の所定位置に配置し、プリント基板5をリフロー工程に流す。これにより、吸着フレーム部材1がプリント基板5上に搭載される。   Next, a method for mounting the suction frame member 1 according to the fourth embodiment on the printed circuit board 5 will be described. As shown in FIG. 11D, the top surface of the stepped portion 346 of the suction member 34 is first sucked by the suction head 7 to hold the suction frame member 1. Next, as in the first embodiment, the suction frame member 1 is disposed at a predetermined position on the printed circuit board 5, and the printed circuit board 5 is flowed to the reflow process. Thereby, the suction frame member 1 is mounted on the printed circuit board 5.

吸着部材34の取り外しに関しては、図11Eに示すように、最初に吸着部材34の段差部346の天面をプリント基板5方向に押し付ける。ここで、段差部346の曲げ根元部345には天面曲げ部344が配置されていないため、天面部341の他の箇所に比べ剛性が低い。そのため、曲げ根元部345がさらに屈曲し、段差部346が沈み込む。そして、更に屈曲した曲げ根元部345を力点、フレーム部材2の天面部21の内側の縁211を支点、フレーム部材2の突起部23と吸着部材3の穴343の嵌合部を作用点として、てこの原理が働く。そのため、第1の実施の形態と同様に、側壁部342が上方向に移動し、吸着部材3がフレーム部材20から取り外される。   Regarding removal of the suction member 34, as shown in FIG. 11E, first, the top surface of the stepped portion 346 of the suction member 34 is pressed toward the printed circuit board 5. Here, since the top surface bending portion 344 is not disposed at the bending root portion 345 of the step portion 346, the rigidity is lower than other portions of the top surface portion 341. Therefore, the bending root portion 345 is further bent, and the step portion 346 sinks. Further, the bent base portion 345 which is further bent is a force point, the inner edge 211 of the top surface portion 21 of the frame member 2 is a fulcrum, and the fitting portion of the projection 23 of the frame member 2 and the hole 343 of the suction member 3 is the action point. The lever principle works. Therefore, as in the first embodiment, the side wall part 342 moves upward, and the adsorption member 3 is removed from the frame member 20.

その後、図11Eに示すように、吸着部材3を取り外したフレーム部材2にカバー部材4を取り付けて、シールドフレーム部材10を構成する。
第4の実施の形態では、吸着部材34の天面部341に段差部346を設けているので、フレーム部材2側に、吸着部材34の天面部341を押し込みのために必要な天面部341と電子部品6との間のクリアランスを考慮しなくともよくなる。そのため、第1の実施の形態に比べ、フレーム部材の高さ、強いてはこれを用いたシールドフレーム部材の高さを、低くすることができる。フレーム部材2の高さを電子部品6と同等にすることで、シールドフレーム部材10の高さを、電子部品6の高さとカバー部材4の厚さの和という、理論上最も低背にすることができる。
Thereafter, as shown in FIG. 11E, the cover member 4 is attached to the frame member 2 from which the adsorption member 3 has been removed, thereby forming the shield frame member 10.
In the fourth embodiment, since the step portion 346 is provided on the top surface portion 341 of the adsorption member 34, the top surface portion 341 and the electrons necessary for pushing the top surface portion 341 of the adsorption member 34 toward the frame member 2 side. It is not necessary to consider the clearance between the parts 6. Therefore, compared with 1st Embodiment, the height of a frame member and the height of the shield frame member using this can be made low. By making the height of the frame member 2 equal to that of the electronic component 6, the height of the shield frame member 10 is theoretically the lowest, the sum of the height of the electronic component 6 and the thickness of the cover member 4. Can do.

(第5の実施の形態)
次に本発明の第5の実施の形態について、図12A〜12Dを用いて説明する。本発明の第5の実施の形態は、その基本的構成・概念は第1の実施の形態の通りである。他方、吸着部材に、取り外し作業をより容易にするための工夫がなされている。なお、フレーム部材の構成、プリント基板への搭載方法等は第4の実施の形態と同様であるため、重複する説明は割愛する。
(Fifth embodiment)
Next, a fifth embodiment of the present invention will be described with reference to FIGS. The basic configuration and concept of the fifth embodiment of the present invention is the same as that of the first embodiment. On the other hand, the adsorbing member has been devised to make removal work easier. Note that the configuration of the frame member, the mounting method on the printed circuit board, and the like are the same as those in the fourth embodiment, and thus redundant description is omitted.

図12A〜12Dには、本発明の第5の実施の形態に係る吸着フレーム部材1が示されている。図12Aは全体斜視図である。図12Bは、吸着部材35単体の、その天面の一部を透視した全体斜視図である。図12Cは、プリント基板5に搭載した直後の断面図(断面は図8と同様)である。また、図12Dは、プリント基板5に搭載後、吸着部材34をフレーム部材2から取り外す時の断面図(断面は図8と同様)である。   12A to 12D show a suction frame member 1 according to a fifth embodiment of the present invention. FIG. 12A is an overall perspective view. FIG. 12B is an overall perspective view of the adsorption member 35 alone, with a part of its top surface seen through. FIG. 12C is a cross-sectional view immediately after mounting on the printed circuit board 5 (the cross-section is the same as FIG. 8). FIG. 12D is a cross-sectional view (the cross-section is the same as FIG. 8) when the adsorption member 34 is removed from the frame member 2 after being mounted on the printed circuit board 5.

図12Aに示すように、吸着フレーム部材1は、フレーム部材2と、その上に着脱可能に配置された吸着部材35とを備えている。図12Bに示すように、吸着部材35は、天面部351と、天面部351の端部に側壁部352と、側壁部352に複数配置された穴353とを備えている。天面部351には第4の実施の形態と同様の方法で剛性の高い箇所と低い箇所が設けられている。側壁部352は、フレーム部材2と接触する方向に、かつ天面部351に対し内側に鋭角に立ち上がって形成されている。   As shown in FIG. 12A, the suction frame member 1 includes a frame member 2 and a suction member 35 detachably disposed thereon. As illustrated in FIG. 12B, the adsorption member 35 includes a top surface portion 351, a side wall portion 352 at an end portion of the top surface portion 351, and a plurality of holes 353 arranged in the side wall portion 352. The top surface portion 351 is provided with a portion having high rigidity and a portion having low rigidity by the same method as in the fourth embodiment. The side wall portion 352 is formed so as to rise at an acute angle in the direction in contact with the frame member 2 and inward with respect to the top surface portion 351.

吸着部材35の装着については、図12Cに示すように、まず吸着部材35の側壁部352は図中の矢印方向に広がるように弾性変形している。そして、吸着部材35の側壁部352でフレーム部材2を挟み込み、フレーム部材2の側壁部22に配置された突起部23と吸着部材35の穴が嵌合されることで、装着されている。従って、嵌合部を外せば、破損せずに着脱可能である。   Regarding the attachment of the suction member 35, as shown in FIG. 12C, first, the side wall portion 352 of the suction member 35 is elastically deformed so as to spread in the direction of the arrow in the figure. Then, the frame member 2 is sandwiched between the side wall portions 352 of the adsorption member 35, and the protrusions 23 arranged on the side wall portions 22 of the frame member 2 are fitted into the holes of the adsorption member 35 to be attached. Therefore, if the fitting portion is removed, it can be attached and detached without being damaged.

吸着部材35の取り外しに関しては、図12Dに示すように、まず第4の実施の形態と同様に段差部356の天面を押すことで、曲げ根元部355が更に屈曲する。そして、第4の実施の形態と同様の原理に基づき、吸着部材35は側壁部がフレーム部材2から外れる。更にこのとき、吸着部材35の側壁部352がフレーム部材2の天面部21を乗り越えると、側壁部352は弾性変形から元の形状(側壁部352が天面部351に対して内側に鋭角に立ち上がった形状)に戻る。すると、押し込み荷重81を除荷しても、吸着部材35の側壁部352の底が、フレーム部材2の天面部21に引っかかる。そのため、吸着部材35がフレーム部材2に再び装着されることがなく、第1〜4の実施の形態に比べ、取り外し時の作業性が増す。   Regarding the removal of the adsorbing member 35, as shown in FIG. 12D, the bending root portion 355 is further bent by first pressing the top surface of the step portion 356 as in the fourth embodiment. Then, based on the same principle as in the fourth embodiment, the side wall of the adsorption member 35 is detached from the frame member 2. Further, at this time, when the side wall portion 352 of the adsorbing member 35 gets over the top surface portion 21 of the frame member 2, the side wall portion 352 rises from the elastic shape to the original shape (the side wall portion 352 rises at an acute angle inside the top surface portion 351. Return to shape. Then, even if the pushing load 81 is unloaded, the bottom of the side wall portion 352 of the adsorption member 35 is caught by the top surface portion 21 of the frame member 2. Therefore, the adsorption member 35 is not attached to the frame member 2 again, and the workability at the time of removal is increased as compared with the first to fourth embodiments.

以上実施の形態を説明したが、各実施の形態に記載した工夫を組み合わせることも可能である。例えば、第5の実施の形態は第4の実施の形態の吸着部材の天面部に段差を設けた工夫を組み合わせているが、これを第1の実施の形態を用いて、平坦な天面部を持つ吸着部材としても良い。また、例えば、第4の実施の形態と第2の実施の形態を組み合わせ、第4の実施の形態の段差の曲げ根元に沿って溝部を形成しても良い。さらに、曲げ根元部を樹脂で形成しても良い。   Although the embodiments have been described above, the devices described in the embodiments can be combined. For example, the fifth embodiment is combined with a device in which a step is provided on the top surface portion of the adsorption member of the fourth embodiment, and this is used to form a flat top surface portion using the first embodiment. It may be an adsorbing member. Further, for example, the fourth embodiment may be combined with the second embodiment, and the groove portion may be formed along the bending root of the step in the fourth embodiment. Furthermore, the bending root portion may be formed of resin.

本発明の効果は、着脱可能な吸着部材を容易に取り外しができ、これを搭載するプリント基板の生産性を向上することができる吸着フレーム部材を提供できることである。その理由を以下に説明する。   An effect of the present invention is to provide a suction frame member that can easily remove a removable suction member and improve the productivity of a printed circuit board on which the suction member is mounted. The reason will be described below.

本発明の実施の形態に係る吸着フレーム部材では、吸着部材の天面部の開口部上にあたる箇所に剛性差を設けられている。フレーム部材の開口部上に位置する吸着部材の天面部を押すことで、剛性が低い箇所のみを屈曲させることができる。ここで、この屈曲部を力点、フレーム部材の天面の内側の縁を支点、フレーム部材と吸着部材との嵌合部を作用点として、てこの原理を働かせている。これにより、フレーム部材と吸着部材との嵌合を外し、吸着部材をフレーム部材から取り外すようにしている。このように、天面部を押し込むという簡単な作業により、吸着部材をフレーム部材から取り外すことが可能となる。そのため、作業者が、ハサミなどの道具を使い、金属を切断するために大きな荷重を加える必要がない。   In the suction frame member according to the embodiment of the present invention, a difference in rigidity is provided at a location corresponding to the opening of the top surface portion of the suction member. By pushing the top surface portion of the adsorption member located on the opening of the frame member, only a portion having low rigidity can be bent. Here, the lever principle is used with the bent portion as a force point, the inner edge of the top surface of the frame member as a fulcrum, and the fitting portion between the frame member and the adsorption member as an action point. Thereby, the fitting between the frame member and the adsorption member is removed, and the adsorption member is removed from the frame member. Thus, the adsorption member can be removed from the frame member by a simple operation of pushing the top surface portion. Therefore, the operator does not need to apply a large load to cut the metal using a tool such as scissors.

もちろん、本発明における吸着フレーム部材は、これを用いるシールドフレーム部材の低背化を阻害するものでは無く、第3の実施の形態、第4の実施の形態に記載した更なる工夫を施すことで、低背化を実現できるのはいうまでもない。   Of course, the suction frame member in the present invention does not hinder the reduction in the height of the shield frame member using the suction frame member, and by applying the further device described in the third embodiment and the fourth embodiment. Needless to say, low profile can be realized.

本発明は、携帯情報端末に限られず、電磁遮蔽を要する電子部品を搭載する全てのプリント基板に適用可能である。   The present invention is not limited to a portable information terminal, and can be applied to all printed boards on which electronic components that require electromagnetic shielding are mounted.
