second bond off

用法例句

From electrical test results before and after IR reflow of two different group samples,coupled with devices failure analysis,it s found the oxidation of lead frame is an important factor for the mechanism of bonding lift,and the thermal mechanical effect in solder reflow can accelerate the occurrence of this potential failure.
