Words of Advice: Will 5G Affect Electronics Manufacturing?

In a recent survey, we asked the following question: How do you think 5G will affect the electronics manufacturing industry? Here are a few of the answers, edited slightly for clarity.

Stitching Capacitor: Crosstalk Mitigation for Return Path Discontinuity

June 13, 2019 | Chang Fei Yee, Keysight Technologies

When the return path is broken due to the switching of reference planes with different potential, e.g., from ground to power or vice versa after layer transition on PCB, the return current might detour and propagate on a longer path, which causes a rise in loop inductance. This might lead to the sharing of a common return path by different signals that pose a high risk of interference among the signals due to higher mutual inductance. This interference results in signal crosstalk. To mitigate the crosstalk due to return path discontinuity (RPD), stitching capacitors are mounted on the PCB to serve as a bridge between the two reference planes of interest on different PCB layers.



In my previous column, Jade Bridges highlighted a few cautionary notes on the pain points associated with thermal management products, particularly the choices that you will be confronted with, such as which material or product type...

Design Rules: For Your Own Good

May 23, 2019 | Andy Shaughnessy, I-Connect007

Like most rules, design rules came about for your own good. And no single designer could possibly remember all of the constraints required to design one of today’s PCBs. But with a set of well-defined design rules, a designer...

There are a number of different factors that influence the protection afforded by potting compounds. The act of encapsulating a component or PCB means that it is surrounded by a layer of resin, which completely seals a component or an...
