ESD stands for electrostatic discharge. During my early days working in a computer firm, all repair tech were provided with a wrist strap to discharge static in our body. The reason we used it was because we were handling motherboards and harddisk. We have learned from our technical school or from books saying that one has to discharge the static from our body before touching any semiconductors particularly the CMOS chip. My question is do you wear any wrist strap before touching semiconductors?
