Insulator damage by weakening of the insulator structures. Junction damage by lowering minority carrier lifetimes, increasing forward-bias resistance and increasing reverse-bias leakage. Metallisation damage by conductor weakening. Catastrophic failures require the highest discharge voltages, are the easiest to test for and are rarest to occur.

Lack of 3-phase electric system connected by star. If neutral breaks off, small-power appliances will be destroyed by overvoltage. Electronic and electrical devices are designed to operate at a certain maximum supply voltage, and considerable damage can be caused by voltage that is higher than that for which the devices are rated.
After fabrication of the BGA package, tiny balls of solder are glued to the pads on its underside; during assembly the balled package is placed on the PCB and heated to melt the solder and, all being well, to connect each pad on the device to its mate on the PCB without any extraneous solder bridging between adjacent pads. Bad connections ...
A crowbar circuit is an electrical circuit used for preventing an overvoltage or surge condition of a power supply unit from damaging the circuits attached to the power supply. It operates by putting a short circuit or low resistance path across the voltage output (V o ), like dropping a crowbar across the output terminals of the power supply.
