Device ESD Sensitivity Testing

December 11th, 2019 No comments

Introduction

Semiconductor devices are susceptible to static discharges to varying degrees. These devices have been becoming more sensitive to Electrostatic Discharge (ESD) since the mid 1990’s. The ESD Association (ESDA) has published a Roadmap for semiconductor devices. Figure 1 shows the ESD sensitivity trend for Human Body Model (HBM) sensitive devices. The ESDA roadmap also contains trends for Charged Device Model (CDM). Read more…

The Difference between Constant Voltage (Under Load) and Open Circuit Resistance Meters

November 23rd, 2016 No comments

During a witness audit last week, a customer asked what the difference was between a resistance instrument Under Load and Open Circuit. The quickest answer to the question is that Constant Voltage (Under Load) instruments would be a Laboratory type instrument, while the Open Circuit is a general indicating instrument.
