ES640 Charged Device Model (CDM) Test System 

1.    Introduction

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.

The Model ES640 is a robotic CDM (Charged Device Model) tester designed to meet all popular CDM ESD test methods, allowing both field induced air discharge methods (FICDM) and relay based contact discharge methods (LI-CCDM, CC-TLP, RP-CCDM). The system includes a computer, environment-controlled chamber, precision XYZ motion system, different types of CDM tester modules, and an automated test and data analysis software.

Here is a comparison between ESDEMC ES640 CDM Solution to others, includingThermo Scientific Orion3 CDM tester, GTS Scorpion Robotic CDM tester, Hanwa HED-C5000R, TET Model 1100, Fraunhofer EMFT MCDM3.
