Description
特許文献1に記載の従来の半導体用パッケージ位置決め用治具501によれば、位置決め部材509が収納部503内で自由に摺動することによって、リードフレーム511の熱膨張に連動してそれぞれの位置決め部材509が摺動し、リードフレーム511と半導体用パッケージ位置決め用治具501の材質との熱膨張係数の差を吸収することができ、半導体用パッケージ507とリードフレーム511をロウ材513によって高い精度で接合することができると考えられる。なお、図7に示すように、半導体用パッケージ位置決め用治具501は、半導体用パッケージ507とリードフレーム511の位置決めを行うための位置決めピン515を備えている。
上記した従来の半導体用パッケージ位置決め用治具501は、本体505に形成した収納部503に、位置決め部材509を摺動自在に配置しているため、半導体用パッケージ位置決め用治具501の全体が縦向きに近い角度で立てられたり、反転されたりした状態で用いられると、位置決め部材509、半導体用パッケージ507が台座上から脱落する。
また、位置決め部材509は、使用を繰り返すうちに欠けや消耗が生じるため、一部を交換する必要がある。
(1) 要素部品を位置決めするカーボン製の位置決め部材と、前記位置決め部材を平面上に支持する台座とを備える電子部品位置決め用治具であって、前記台座は前記位置決め部材に係止する枠部材と該枠部材を固定する本体部とで形成され、前記位置決め部材は、前記台座の枠部材を接合手段により前記台座の本体部に固定することにより該台座の枠部材と該台座の本体部との間で前記台座の本体部上を変位可能に挟持され、前記位置決め部材は複数に分割され、前記複数に分割した位置決め部材は、該位置決め部材を集合状態に配列した際に互いに隣接する位置決め部材間で係合する係止部を備えると共に、外側に配列された前記位置決め部材の外周縁のみが前記台座の枠部材により係止されることを特徴とする電子部品位置決め用治具。
また、本発明の電子部品位置決め用治具によれば、台座の本体部に、複数の位置決め部材が縦横に隣接して配置され、外側に配列された位置決め部材は、外周縁が枠部材によって本体部に係止され、脱落が抑制される。この脱落の抑制された外側の位置決め部材に、内側で隣接する位置決め部材は、その隣接部が係止部によって外側の位置決め部材と本体部との間に挟まれ、脱落が抑制される。つまり、全ての位置決め部材が摺動自在となり、且つ脱落が抑制される。また、内側に隣接する位置決め部材であっても、本体と枠部材とを繋ぐ接合手段を取り外すことにより、位置決め部材を傷つけることなく位置決め部材を交換できる。また、位置決め部材を細かく分割できるので、基材と電子部品位置決め用治具の熱膨張係数が大きく異なっても発生する熱応力を小さくすることができる。
図1は本発明の実施形態1に係る電子部品位置決め用治具の断面図である。
本実施の形態に係る電子部品位置決め用治具11は、要素部品13を位置決めするカーボン製の位置決め部材15と、位置決め部材15を平面上に支持する台座17とに大別して構成される。位置決め部材15は、要素部品13を収納する要素部品収納部19を露出させて有している。台座17は、位置決め部材15に係止する枠部材21と、枠部材21を固定する本体部23とで形成される。
本実施形態の要素部品13は半導体素子であり、後述する基材27はセラミック基板である。
C/Cコンポジット材とは、炭素繊維強化炭素複合材のことを言う。
C/Cコンポジット材若しくは黒鉛材の表面にガラス状カーボンが被覆された炭素材とは、C/Cコンポジット材又は黒鉛材の表面にポリ塩化ビニルを熱処理したピッチ、フェノール樹脂、フラン樹脂、コプナ樹脂などを塗布し、炭素化してガラス状炭素の被膜を形成したもののことを言う。
C/Cコンポジット材若しくは黒鉛材の表面に熱分解炭素の被膜を形成した炭素材とは、CVD炉内でC/Cコンポジット材又は黒鉛材の表面にメタン、エタン、プロパン、ブタン、エチレンなどの炭化水素ガスの熱分解した被膜を形成したもののことを言う。
枠部材21は、耐熱性があればどのような材質であってもかまわない。枠部材21は、例えばアルミナ、ジルコニア、窒化珪素、窒化アルミニウム、カーボン等のセラミック、ステンレス等の鉄系合金、白銅、洋白、青銅、黄銅などの銅合金などの金属等が挙げられる。枠部材21はカーボンであることが好ましく、さらに黒鉛材であることがより好ましい。枠部材21は、位置決め部材15の要素部品13を収納する面に存在しているので、カーボンであれば熱衝撃に強く、要素部品13あるいは基材27と摩擦が生じても、要素部品13あるいは基材27を摩耗させたり傷つけたりすることがないので好ましく、黒鉛材はカーボン部材のうちでも特に軟らかいのでより好ましい。
ロウ付けを行うロウ材としては、銀系、リン銅系、アルミ系のロウ材の他、銀ペーストなどの金属ペースト、半田などがが挙げられ、特に限定はされない。
図3に示す本発明の電子部品位置決め用治具の変形例において、位置決め部材15は、複数に分割され、外側に配列された位置決め部材15の外周縁のみが台座17の枠部材21により係止される。複数に分割した位置決め部材15は、位置決め部材15を集合状態に配列した際に、互いに隣接する位置決め部材15同士で係合する係止部39を備える。このため、従来の電子部品位置決め用治具の構成では図2(a)に示すように、それぞれの位置決め部材509が相互に離間して配置されていたが、本発明の実施形態2に係る電子部品位置決め用治具11では図2(b)に示すように、係止部39を介して連続して配置されることになる。また、図3に示すように、本体部23は、位置決め部材の裏面の一部が露出するよう開口部があってもよい。位置決め部材の裏面にも要素部品収納部を形成し、電子部品位置決め用治具の両面を利用し、位置決めすることができる。
枠部材21は複数に分割可能に構成することが好ましい。図4に示した電子部品位置決め用治具例では、枠部材21が、第一枠部材41、第二枠部材42、第三枠部材43、第四枠部材44に分割されている。枠部材21を分割可能とすることにより、複数の位置決め部材15の一部に交換の必要が生じた場合、交換対象となる位置決め部材15を直接、あるいは間接的に固定している第一枠部材41又は第二枠部材43のみを固定解除すれば交換対象の位置決め部材15が脱着可能となり、交換不要な他の位置決め部材15は固定したままとして、交換作業を省力化できる。
位置決め部材15の表面には、位置決め用のピン35が設けられている。ピン35は金属製であり、位置決め部材15に形成されたピン孔45に裏面から挿入されている。これにより、ピン35が摩耗、湿炭、消耗しても交換することができる。さらに、位置決め部材15の表面に位置決め用のピン35を備え、このピン35を基材27に形成された位置決め穴に挿入すると、位置決め部材間の間隙37を適宜に形成することができる。
ピン35は、位置決め部材15に形成されたピン孔45に相対し、位置決め部材15の要素部品実装面に突き出る突出部47と、突出部47の反対側の基端部49を有し、基端部49には突出部47の直径を超える太径部51が形成される。この構成により、ピン35が位置決め部材15の表側から抜けず、枠部材21と本体部23を分離すれば、ピン35を容易に交換することができる。また、ピン35とピン孔45には隙間があることが好ましい。ピン35と、カーボン製の位置決め部材15との間に隙間があると、浸炭してもピン35を位置決め部材15から抜けやすくできる。
浸炭とは、金属中に炭素か侵入することを言い、ピンが浸炭されると、ピンが太くなったり、表面が粗くなったりし、抜けなくなる問題が発生する。
電子部品位置決め用治具11では、台座17の本体部23に位置決め部材15が配置され、接合手段29によって本体部23に固定された枠部材21が、本体部23との間に位置決め部材15を挟持する。本体部23と枠部材21によって挟持された位置決め部材15は、本体部23の平面上で変位可能となる。これにより、位置決め部材15が平面上で変位(自由に摺動)することで、基材27の熱膨張に連動してそれぞれの位置決め部材15が摺動し、基材27と電子部品位置決め用治具11の材質との熱膨張係数の違いにより発生する熱膨張差が吸収される。これに加えて、電子部品位置決め用治具11の全体が縦向きに立てられたり、反転されたりしても、位置決め部材15が台座上から脱落することがない。また、位置決め部材15にピン35が設けられている場合は、基材27、電子部品13も台座17から脱落しなくなる。
