I am using Nylon plastic screws as PCB mounts on my 2 layer PCB. The PCB has a very ESD sensitive and expensive device mounted on.
Since the Nylon material can develop positive static charge, is it a good idea to have 4 nylon screws on the PCB which houses a very ESD senstive device?
The PCB is to be screwed onto an ESD conductive box.
(The reason why I am not preferring Standard metal screws is that there a chance of an external charge can travel via the screws to the board/device and damage it.)
