Abstract

A printed circuit board's ability to withstand static discharge is enhanced by the following process. A non- conductive paint is applied to the solder side of the circuit board. Before applying the paint, a grounding point is masked off. After the paint has dried, the mask is removed and conductive nickel paint is applied. The nickel paint will be electrically connected to the grounding point on the board through the masked-off area and function as the ground plane for the board. This process enables a printed circuit board to withstand 4500 volts of electrostatic discharge whereas without this process 1900 volts was the maximum the board could withstand.
