What is FR-4?
FR-4 is a commonly used dielectric material in Printed Circuit Boards (PCBs). It separates copper layers in PCBs and provides mechanical support. It is a standard material as per the National Electrical Manufacturers Association (NEMA), which is made of a composite material achieved by combining fiberglass and epoxy resin.
FR stands for "Flame Retardant", which means that FR-4 meets the standard of UL94V-0 on plastic inflammability. The number 4 indicates its grade in the family of glass epoxy laminate materials. This material can stop the expansion of fire and immediately extinguish it when the material burns.
Process of FR4 PCB Assembly
In this procedure, the bare substrate of the FR4 PCB is used to attach electronic components. The procedures for assembling a FR4 PCB are exactly the same as those for assembling any other PCB. An electronic component’s assembly is a challenging process that frequently calls for specialized equipment and tools.
One very typical type of electronic assembly is the assembly of circuits on the circuit boards. Based on the project’s complexity, design, and size requirements, circuit board assembly can differ greatly.
