Proper Grounding Techniques
Before removing the CMX158886 from its static bag, proper grounding techniques must be used to prevent
electrostatic discharge (ESD) damage to the cpuModule. Common grounding procedures include an anti-static
mat on a workbench, which may connect to an anti-static wrist strap (also known as an ESD wrist strap) on the
wrist of the technician or engineer.
