Description
レーザー照射;41Aで2ms
半田ボール径;100μm
[実施例]
図7(A)を見ると、半田接合前はピッチ角110〜115′付近でピークになっているのに対し、半田接合後はピッチ角85〜90′付近でピークになっており、半田接合前後におけるピーク位置の違いは25′程度であることがわかる。
[表1]
半田接合前 半田接合後 変化量
最大値 143.25′ 116.27′ −25.9′
平均値 112.265′ 84.698′ −27.567′
最小値 96.82′ 67.8′ −29.97′
最大−最小 46.43′ 48.47′ 4.88′
[比較例]
図7(B)を見ると、半田接合前はピッチ角120′付近でピークになっているのに対し、半田接合後はピッチ角70〜75′付近でピークになっており、半田接合前後におけるピーク位置の違いは50′程度であることがわかる。また、半田接合後は、半田接合前よりもピッチ角のピークの傾斜が緩やかになっていることがわかる。
[表2]
半田接合前 半田接合後 変化量
最大値 147.95′ 107.29′ −40.45′
平均値 119.828′ 66.982′ −52.847′
最小値 102.91 41.34′ −104.46′
最大−最小 45.04′ 65.95′ 64.01′
図7及び表1、表2からも明らかなように、半田接合前後におけるスライダ姿勢の変化量は、比較例(最大−最小の変化量64.01′)よりも、実施例(最大−最小の変化量4.88′)で大幅に小さくなる。よって、変形容易部41を具備する本実施例のほうが、変形容易部を具備しない比較例よりもスライダ11の姿勢変化を抑制できるといえる。
