Be sure to put on a wrist-strap for grounding (with impedance lower than 10® 92) whose other end-is

The strap works to drain away the static electricity build-up on the human body,
Grounding for the work table
Be sure to lay on the table a conductive sheet (with impedance lower than 10° 2) such as a sheet of
