BICHENG PCB WORSHOP:
PTFE is a useful material for the fabrication of PCB. Teflon PCB has
its unique advantage of temperature resistance. PTFE PCB Board is a
high-frequency PCB with polytetrafluoroethylene (PTFE) as the PCB
substrate.
MAJOR MATERIAL SUPPLIERS:
Metal core PCB, also known as thermal PCB or metal backplane PCB, is a PCB that uses metal material as the substrate of the heat sink part of the substrate. In Metal Core PCB, thick metal covers one side of the PCB.
PCB surface finish is critical for printed circuit boards because it
prevents copper (exposed traces, pads, holes, and ground planes) from
oxidizing—a key factor in achieving advanced application performance.
Contact us for assistance choosing a finish, such as Tin Surface Finish PCB.
