Electrostatic Discharge Testing

Electrostatic discharge (ESD) is defined as the transfer of static charges between bodies at different electrical potentials. ESD impacts productivity and product reliability in virtually every aspect of today's electronics environment. It can change the electrical characteristics of a semiconductor device, degrading or destroying it. It can upset the normal operation of an electronic system, causing equipment malfunction or failure. In clean rooms, charged surfaces can attract and hold contaminants, making removal from the environment difficult.

We provide the following ESD tests for electronic parts and packaging materials:
Surface Resistance Test
Static Decay Test
Triboelectric Charge Accumulation
Capacitive Probe Test

Surface Resistance Test

Meter to use: Model 803B Resistance/Resistivity Probe

For insulative work surface, Point-to-Point resistance (RTT) will be measured
For conductive work surface, Resistance-to-groundable Point (RTG) will be measured

Static Decay Test
Meter to use: Charge Plate Monitor (CPM)
Place the specimen on CPM, Charge the specimen to certain voltage and record the decay time.
Triboelectric Charge Accumulation


This test measures the charge developed on Teflon and Quartz cylinders when rolled down a test material mounted to a plane inclined at 15o.
Place the specimen on a grounded conductive surface and measure the charge accumulation.
