PCB Assembly (PCBA) Design Guide

Ultimate PCB Assembly Guide

PCBs, or printed circuit boards are the unsung heroes of modern electronic devices. Most end-users have no idea how the components inside the electronics they know and love work together. However, for engineers, OEMs, and designers, there’s a lot to know — and love — about PCBs.

This PCB design guide was created to help new and seasoned engineers make more informed design decisions early on so they can end up with the perfect components for their products.

Let’s start with the basics:


Common questions about printed circuit boards

What is a PCB?

A printed circuit board or PCB is a central piece of any electronic device. It has two primary
functions:• House the electronic components
• Connect components for operation

The board itself is made of a non-conducting substrate, such as fiberglass, that is coated with copper on one or both sides. The copper conducts electricity and is etched away from the board leaving the appropriate components to be connected to each other through the circuit.
