Description
図1に示す光電気混載基板を、前記の製法にしたがって作製した。ただし、配線部Bの長さは20cmとした。また、金属補強層として、厚み20μmのステンレス層を設けた。そして、金属補強層のうち、幅狭部の根元角部のアールの曲率半径Rを1.5mmとし、その配線部側に突出した先端角部のアールの曲率半径R′を0.8mmとした。また、幅広部の幅Tと幅狭部の幅T′との割合(T:T′)は、1:0.3とした。そして、絶縁層の厚みを5μm、アンダークラッド層の厚み(絶縁層の裏面からの厚み)を10μm、コアの厚みを50μm、コアの幅を50μm、オーバークラッド層の厚み(アンダークラッド層の表面からの厚み)を70μmとした。そして、電気配線の厚みを5μmとした。
金属補強層にアールを設けず、図8(b)に示すような形状とした。それ以外は、上記実施例1と同様にして、光電気混載基板を作製した。
上記実施例1および比較例1に用いた発光素子、受光素子と同様の発光素子、受光素子を準備した。すなわち、発光素子は、ULM社製のULM850−10−TT−C0104Uである。受光素子は、Albis optoelectronics 社製のPDCA04−70−GSである。そして、上記発光素子から発光された光を直接、上記受光素子で受光した際の光量I0 を測定した。つぎに、上記実施例1品と比較例1品のそれぞれに対し、幅方向に1周ねじった状態にして、左右方向に0.5Nの力で引っ張って固定し、光電気モジュール部A′に設けられた発光素子から発光された光を、光導波路Wのコアを経由して、電気モジュール部Aに設けられた受光素子で受光し、その受光した光量Iを測定した。そして、それらの値から〔−10×log(I/I0 )〕を算出し、その値を光挿入損失とした。その結果、実施例1品の光挿入損失は、2.3dBであった。これに対し、比較例1品の光挿入損失は、2.8dBであり、実施例1品の方が、光挿入損失が抑制されていることがわかった。
上記実施例1品と比較例1品のそれぞれに対し、上記光挿入損失の測定時と同様に、幅方向に1周ねじった状態にして、左右方向に引っ張った。そして、その引張荷重を増加させていき、配線部Bが破断する際の値(破断強度)を確認した。その結果、実施例1品の破断強度は12N、比較例1品の破断強度は6Nであり、実施例1品の方が、比較例1品に比べて破断強度がはるかに高いことがわかった。

Claims (5)
- 帯状に延びる絶縁層の少なくとも片端部が、その表面側に導電パターンからなる電気配線と光素子とを備える光電気モジュール部に形成され、上記絶縁層の、光電気モジュール部から延びる部分が、その裏面側に上記光電気モジュール部の光素子に光結合される帯状の光導波路を備える配線部に形成された光電気混載基板であって、上記絶縁層の厚みが3〜50μmであり、上記絶縁層裏面の、上記光電気モジュール部と配線部にまたがる部分に金属補強層が設けられており、上記金属補強層のうち、配線部に設けられた部分の幅T’が、光電気モジュール部に設けられた部分の幅Tに比べて狭く設定され、上記T:T’は1:0.98〜1:0.05であり、上記金属補強層の幅が狭くなったところの根元角部に、曲率半径Rが0.3〜5mmのアールが付けられていることを特徴とする光電気混載基板。
