Printed circuit board FR4 pcb double layer pcb use in electronics
Fr4 Circuit Board is fiberglass. It is the most common PCB material. FR4 1.6mm thick consists of 8 layers of # 7628 fiberglasses. The manufacturer’s logo / designation of the red flammability class is located in the middle. The temperature for using this material is 120 – 130 ° C.
What is FR5?
FR5 is fiberglass similar to FR4, but the temperature of use of this material is 140 – 170 ° C.
What is CEM-1?
CEM-1 is a paper backed laminate with one layer of # 7628 glass fabric. This material is not suitable for plating through holes.
What is CEM-3?
CEM-3 is most similar to Fr4 Circuit Board. Construction: fiberglass mat between two outer layers of # 7628 glass fabric. CEM-3 milky white very smooth. The price of this material is 10-15% lower than that of FR4. The material is easy to drill and stamp. It is a complete replacement for FR4 and has a very large market in China.
