What is PTFE Copper Clad Laminate and Why is it Used in PCBs? – PCB & MCPCB
PTFE copper clad laminate is one of the most important base materials in high-frequency printed circuit boards. It is made by bonding copper foil with PTFE, also known as polytetrafluoroethylene. This material is widely used in microwave, RF, and high-speed digital circuits where low signal loss and stable performance are critical. While FR-4 laminates serve … [Read more…]
