FR-4 Printed Circuit Boards

FR-4 is the most popular material for rigid PCBs. Do you need FR-4 printed circuit boards? Maybe you think so, but perhaps you’re not quite sure. When exactly do you need PCBs made from FR-4 material? Check out the differences between ceramic PCB, FR-4 boards, and MCPCB.

What Is FR-4 Material?

First, it’s important to understand what FR-4 material is. FR means “flame-retardant,” and it applies to a fiberglass-reinforced epoxy-laminated sheet that makes it an ideal substrate for electronic components on a printed circuit board. The fiberglass provides the rigid structure made even more rigid and flame-resistant by the epoxy resin.

FR-4 material is so popular because of its many wondrous qualities that can benefit printed circuit boards. In addition to being affordable and easy to work with, it is an electrical insulator with very high dielectric strength. Plus, it’s durable, moisture-resistant, temperature-resistant and lightweight. You can use FR-4 PCBs in virtually any electronic application.
