FR4 PCB Introduction

--Definition

  FR means "flame-retardant," FR-4 (or FR4) is a NEMA grade designation for glass-reinforced epoxy laminate material, a composite material composed of woven fiberglass cloth with an epoxy resin binder that makes it an ideal substrate for electronic components on a printed circuit board.

-Pros and Cons of FR4 PCB

  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.

  FR-4 is a widely relevant material, popular mostly for its low cost and relative mechanical and electrical stability. While this material features extensive benefits and is available in a variety of thicknesses and sizes, it isn't the best choice for every application, especially high-frequency applications like RF and microwave designs. 

-Multi-layer PCB Structure

  Multilayer PCBs further increase the complexity and density of PCB designs by adding additional layers beyond the top and bottom layers seen in double-sided boards. Multilayer PCBs are built by laminating the various layers. The inner layers, normally double-sided circuit boards, are stacked together, with insulating layers in between and between the copper foil for the outer layers. Holes drilled through the board (vias) will make connections with the different layers of the board.
