Description
開口54aの形成は、例えばメッキレジスト54の感光性を用いて行われ、そのときホール35a内のレジスト膜も除去される。ここで、ホール35a内のレジスト54の除去と開口54aのパターニング精度を両立させるためには、ホール35a内に照射が不要なネガ型レジストをレジスト54として用いることが望ましい。また、開口54aの径をホール35aの径よりも大きくすることによって、後述のメッキ性が向上するため、より好ましい形態である。
図10(d)の構造においては、外部端子41内に銅からなる金属ピラー31が食い込んでいるため、外部端子41が完全に潰れてしまうことがない。従って、加圧しながら実装すれば、金属ピラー31が実装基板側の電極端子に触れた状態で実装できるため、上記16.2(K/W)の熱抵抗で実装することが可能となる。
一方、比較例の構造においては、外部端子41が完全に溶融してしまうため、押し潰して実装することが困難であり、熱抵抗も上記計算通り35.4(K/W)となってしまう。
上記のように図10(d)の構造は、比較例よりも熱抵抗が低く、放熱性に優れる。
