Surface Scan on IC Level with High Resolution

The development of a low-noise emission PCBs is becoming more difficult because of higher integration densities, faster clock cycles, as well as integrating more radiators like wireless capabilities on to the IC. Based on these design challenges, it is essential to get all of the necessary information for the electric parts before they are placed on a customer’s PCB. Read on for advice on how to detect electromagnetic disturbances above ICs.

Characterizing & Debugging EMI Issues for Wireless and IoT Products

An increasing number of manufacturers are adding or retrofitting wireless technology into new or existing products. These products typically include mobile, household, industrial, scientific, and medical (ISM) devices. This transition towards “everything wireless” is in full swing, and with it comes problems with electromagnetic interference (EMI) from the product itself interfering with sensitive on-board cellular, GPS/GNSS, and Wi-Fi/Bluetooth receivers. Read on to find out what to do about it.

Shielding and Filtering Are Not Independent of One Another

I have lost count of the number of times I have been asked to fix an EMC problem, only to find that a shielding box has been designed or purchased to provide XdB up to fMAX. Or a filter has been designed or purchased with a similar specification, but to reduce cost the filter has been mounted on a printed circuit board (PCB) inside the box, with a cable from it entering or exiting the box through a plain connector.
