Printed circuit boards (PCBs) are used in everything from televisions to high tech military applications and everything in between. PCBs are the backbone of the electronics industry.
Materials:
There are a wide range of materials used in the manufacturing of printed circuit boards.
The most common being a fiberglass and resin combination known as FR-4. There are other materials such as Teflon, and paper based materials
Printed circuit board basics: There are a few basic steps for standard double sided printed circuit boards.

Look for each step and other procedures associated with multilayer PCBs featured here in the coming weeks.
Most all PCB also go through several inspections and testing throughout the process. Once the board passes electrical and visual inspection it is ready for population of the components.
