Charged Device Model (CDM) electrostatic discharge is a common cause of microelectronic circuit failure. Sensitive devices can be seriously damaged or destroyed by a CDM discharge at relatively low voltage. This often occurs when the static charged device contacts a metal surface at a different potential. Such an electrostatic discharge often has an extremely fast rise time. ESDEMC provides CDM test service up to 4kV, and the maximum test area up to 375 X 425 mm.
