Conclusions
1) Solder ball shear and ball pull tests produced a high incidence of brittle fracture with increasing test speed, independent of pad finish or aging time.
2) The IMC on packages with an OSP pad grew faster than on devices with ENIG plating, and samples with OSP pads generated more brittle solder joint failures in ball shear/pull tests after thermal aging.
3) Solder ball pull testing (compared with shear) generated a higher percentage of brittle failures at all test speeds.
4) Compared to the specimens with ENIG pad finish, the ball shear/pull strength and fracture energy of specimens with OSP decreased more rapidly with aging time. This phenomenon most likely relates to the thicker Cu-Sn.

飞秒激光器的突发模式对透明材料处理的影响Effects of burst mode on transparent materials processing
We investigated the effect of burstmode with nanosecond (ns) time delay between subpulses on sodalime glass volume machining. We observed in tight focusing configuration that the use of burstmode with ns time delay between subpulses does not increase the absorption efficiency and does not bring a significant effect on the heat affected zone diameter with respect to single pulse mode. On the contrary in loose focusing configuration the use of burst mode allows increasing the aspect ratio of the heat affected zone without extra energy absorption. This effect is highly interesting for filamentation glass cutting applications.
