ESD Precautions

By on September 11, 2010

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?

    I never used it..but I put my hands together or touch metal before touching any electronic parts. not the best way to do things but so far so good.

    Hi Waleed,

    I guess it is more suitable for those who deal with motherboard and the harddisk and other very sensitive boards. So far touching parts on the Monitor, TV, power supplies and even printers have no problem.

    Absolutely! I have seen the effects of ESD on a silicon level when I told our QA to dissect an IC because of a low yield. These are usually burnt holes on the silicon. But modern IC's have a built-in protection for ESD. As precaution, I implemented this in our board repair dept.

    Hi, can you introduce a little bit about ESD and the use of ESD to me?
