What Is Fr4
What is FR4 and how does it matter to your printed circuit board design (PCB)? The FR stands for flame retardant, and the 4 signifies type 4 woven glass reinforced epoxy laminate. FR4 is often used for insulating PCBs because it holds up well in a variety of conditions and environments.
