The Industry 4.0 IoT platform automatically becomes a reliable and dependable venue for compliance verification, eliminating the traditional way of tedious predefined period manual checks.

The mirror technique is a very old technique to be used with PCBs when failing in radiated EMC tests. An easy solution to avoid changes in layout if the technique can be applied to your product.

ESD simulators a.k.a. “ESD Guns” play an important role in product development and their proper selection and use are considered essential to any EMC test laboratory. The focus of this paper is on ESD simulators that perform testing of complete apparatus in accordance with IEC 61000-4-2 and other system level test standards.

This article discusses the crosstalk reduction between PCB traces by utilizing a guard trace between the traces and investigating the effect of the guard trace grounding.

Clock signals from 1 to 100MHz are usually responsible for radiated EMC problems in HF/VHF range. Harmonics are the culprits, but think in current, not in voltage.

Often (very) fast transients have been proven to trigger latch-up. This kind of latch-up is called transient induced latch-up, commonly known as “transient latch-up” (TLU).
