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.

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 ...

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 ...

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 ...

This is the first of several articles in the PCB Design Best Practices series, which discusses the different steps of PCB development from the basics of creating a design schematic with specific ...

Once a printed circuit board (PCB) has been assembled it’s rather hard to look inside of it, which can be problematic when you have e.g. a multilayer PCB of an (old) system that you really would like ...
