We provide tests on packages and interconnects (component back-end), in order to evaluate various issues :
Control of the quality of microelectronic assembly operations : bonding (wire pull, ball shear), die attach (die shear)
Aging effect of mechanical resistance
Package hermeticity (fine / gross leaks)
Internal particles detection (PIND)
We perform these tests on semiconductor devices back-end: wedge bonding, BGA, ball bonding, die attach.
