why are dip switches static sensitive

<< < (3/5) > >>

cdev:
I've seen some DIP switches that integrated LEDs into the switch in the past.

wraper:
You don't want to bring non ESD safe stuff into ESD safe area.

You want as little non-dissipative material at your esd workbench, especially not square meters of packaging material for non-sensitive parts.  :-//

EGGzactly!  When opening a bunch of static-sensitive parts and putting them into P&P feeders or whatever, you don't want any static-producing materials in the same area.  When receiving non-safe materials, they'd have to be opened someplace else and then repakaged static-safe before moving to the all-safe work area.

Personally, I think people go overboard on this stuff, but if you have less well-trained people handling these things, then the materials and procedures need to be set up to avoid problems.

I knew that ESD was getting out of hand when I received some 1/4-20 UNC stainless steel bolts in anti-static packaging.  Obviously, the vendor had standardized on those bags to make his life simpler.

Many people don't want any packaging in the assembly area which can build a static charge. You may know which parts have static issues and which don't, but don't expect similar knowledge among the production line staff who have to unpack the tubes and reels of parts, and load them into the PNP machines. If everything they handle is made to similar static dissipative standards, it keeps life simple.
