Before handling any PCB or LCD assemblies, ensure you are properly grounded and that all handling of PCB or LCD assemblies is protected:
a) Use of ESD wrist straps is required any time a PCB or LCD is handled outside of a silver ESD protective bag, including but not limited to when they are installed inside assemblies. Ensure the inner metal button of the wrist strap is contacting your skin.
b) All work should be performed upon an ESD work mat
