If you have done any sort of radio work you probably have a fair idea about what antennas do. It is pretty easy to have a cursory understanding of them, too. You probably know there’s somethi…

As a circuit board manufacturer, designers often ask us about the difference between IPC Class 2 and Class 3. Class 1 does exist although we rarely produce boards that fall into this classification. Most of the times, even if the end-use of the product only requires Class 1. We will make it Class 2....

Electron microscopes were once the turf of research laboratories that could foot the hefty bill of procuring and maintaining such equipment. But old models have been finding their way into the hands of eager individuals who are giving us an inside look at the rare equipment. Before you start scourin...

Ben Krasnow has a vision of future electronics: instead of the present PCB-screwed-into-a-plastic-box construction, flexible circuits will be deposited straight onto the plastic body of the device itself, merging the physical object and its electronics. There is existing copper-on-plastic technology...

Designing circuit boards for high speed applications requires special considerations. This you already know, but what exactly do you need to do differently from common board layout? Building on where I left off discussing impedance in 2 layer Printed Circuit Board (PCB) designs, I wanted to start ta...

Background – Common Mode and Differential Mode Noise We shall have a power supply input to the system we are working on. In this case, the power signal input to the system should return back the same without any additional noise. If any additional noise adds on to the ground plane, then there is a...
