In designing a PCB, one will encounter various types of holes. These holes are placed in different layers according to how the holes/cut-outs are used in a PCB design tool. The different layers for ...

Many readers are certainly familiar with the process for home-etching of PCBs: it’s considered very straightforward, if a little involved, today. This was not the case in my youth, when I first ...

How are the inner layers of a multilayer PCB printed? PCBs can be single sided, double sided or multi-layered. Multi-layer PCBs are boards which have copper layers in the outside and inner portions.

Learning to lay out a printed circuit board takes some time. But after you’ve churned out a few it’s really pretty easy. If you find yourself at that point it may be time to learn about more ...

Multi-layered printed circuit boards (PCBs) are typically preferred because they offer high signal intensity. Of all the multi-layered types, the 2-layer PCB is the most common, as it can accommodate ...

Printed-circuit-board (PCB) substrate material, like FR-4 glass epoxy, is a poor conductor of heat. Conversely, copper is an excellent conductor of heat. So, more copper area on a PCB is ideal from a ...
