摘要

在摆锤试验中，SAC305/ENIG接头分别在150℃时效500h和1000h下进行了高冲击速度(200mm /s、1000mm /s)试验。初步结果表明:无论时效时间如何，再流试样的峰值力、峰前能和除后能外的总冲击能均大于时效试样;对于再流态SAC305/ENIG接头(直径0.3 mm)，在速度为1000 mm/s时，最大作用力为2.592 N;的

Interfacial toughness evaluation of SAC305 solder bump with pendulum impact test

The high impact speeds (200, 1000 mm/s) in the pendulum test were conducted on the SAC305/ENIG joints aged at 150°C for 500 and 1000 h, respectively. The preliminary results exhibit that the peak force, pre-peak energy and total impact energy except post-energy of as-reflowed are larger than those of as-aged samples regardless of aging time. For the as-reflowed SAC305/ENIG joint (0.3 mm at diameter), the peak force is 2.592 N at the speed of the 1000 mm/s; the
