Printed Circuit Board FR4 Pcb Double Layer Pcb Use In Electronics
Printed circuit board FR4 pcb double layer pcb use in electronics
What is Fr4 Circuit Board?
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.
