testing

Human Body Model (HBM) is the original ESD test method for semiconductor devices and...

CDM discharges exhibit a fast initial current step when the stray capacitance of the pogo pin is charged. It is demonstrated that the high slew rate can damage sensitive gate oxides. The miscorrelation of CDM and CC-TLP methodologies is addressed by applying pulses with 20 ps rise time.

Cable discharge events occur more frequently than we think, but they often go unrecognized or undiagnosed for root causes, resulting in unnecessary device failures. This article discusses the origins of three types of cable discharge events.

In this second part of a two-part article, we’ll discuss the use of radio modules to enable wireless connectivity of electronic and consumer products, and how to approach radio, EMC and safety regulatory approvals in the European Union for radio modules and equipment which contain radio modules.

Without much effort and expense, it is possible to perform pre-compliance testing in a manner that saves considerable time and money without commercial or financial risks associated with purchasing a full-compliance test facility.

In this first part of a two-part article, we’ll discuss the use of radio modules to enable wireless connectivity of electronic and consumer products, and how to approach radio, EMC and safety regulatory approvals in North America for radio modules and equipment which contain radio modules.

Understanding radio compliance and electromagnetic compatibility (EMC) issues to help ensure that products meet regulatory testing requirements and customer expectations.

This article discusses the requirements for the qualification of an Open Area Test Site or Semi Anechoic Chamber for measuring radiated disturbances from 30 MHz to 1 GHz.

The voltage based CDM classification has practically no meaning for IP qualification. In this article, we propose an alternative CDM qualification, which is based on a peak current criterion.

This article presents the results of experiments to measure the effectiveness of lossy material in reducing RF emissions from perforated air vents such as those commonly used on computer enclosures. The results show good performance compared to those with conventional metal vents.
