Product Description

FR4 Double Sided Pcb PCBA Printed Circuit Board Assembly Supplier

 

 

FR-4 is a composite material composed of woven fiberglass cloth with an epoxy resin binder that is flame resistant (self-extinguishing).

"FR"  stands for "flame retardant", and does not denote that the material complies with the standard UL94V-0 unless testing is performed to UL 94, Vertical Flame testing in Section 8 at a compliant lab. The designation FR-4 was created by NEMA in 1968.

FR-4 glass epoxy is a popular and versatile high-pressure thermoset plastic laminate grade with good strength to weight ratios. With near zero water absorption, FR-4 is most commonly used as an electrical insulator possessing considerable mechanical strength. The material is known to retain its high mechanical values and electrical insulating qualities in both dry and humid conditions. These attributes, along with good fabrication characteristics, lend utility to this grade for a wide variety of electrical and mechanical applications.

 

FR4 PCB are the printed circuit boards using FR4 laminates. Most PCBs are made of FR4 (Flame Retardant level 4).

Beneficial Properties of FR4 Circuit Board: 

The FR4 printed circuit boards have also gained popularity owing to the following reasons:

  •  FR4 is a low-cost material.
  •  It has a high dielectric strength which contributes to its electrical insulation properties.
  •  The material has a high strength-to-weight ratio and is lightweight.
  •  It is moisture resistant and has relative temperature resistance as well.
  •  The material has good electric loss properties.
  •  FR4 doesn’t absorb water, which makes it suited for various marine PCB applications, too.
  •  The material is yellow to light green in color, which perfectly goes with any application.

All these properties make it suitable in a variety of environments.
