The MS2131 has dedicated ESD requirements. To ensure the proper connection between the
MS2131 and the user interface board reference ground, it is recommended that copper studs
or other low-impedance metal fasteners be used for the copper exposure (to connect to an
interface reference ground) of the positioning holes on the user interface board.
