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 ...

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 ...

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 ...

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 ...
