FR4 is a widely used composite material in printed circuit board (PCB) manufacturing. It is composed of woven glass fiber fabric and epoxy resin, which together create a strong, durable, and reliable substrate. The name “FR4” stands for Flame Retardant Level 4, indicating its excellent fire resistance, which is a key requirement in electronics
What is Roger Laminate
1.Roger Laminate: Roger laminate is advanced circuit board substrates manufactured by Rogers Corporation, specifically engineered for high-frequency and high-performance electronic applications. Unlike the widely used FR4, which is glass-reinforced epoxy laminate, Rogers materials are made from hydrocarbon ceramic or PTFE composites. Their cons
