China Wholesale Cpu Pcb Pricelist - 10 Layer Impedance Control Resin Plugging PCB 3 – Huihe
The difference between electroplating plug hole and resin plug hole 1. Surface difference: The electroplating plug hole is filled by copper plating, and the inner surface of the hole is full of metal. The resin plug hole is filled with epoxy resin after copper plating on the hole wall, and finally copper plating on the resin surface. The effect is that the hole can be conducted, and there is no dent on the surface, which does not affect the welding. 2. The process is different Electroplating ... -
China Wholesale Flex Printed Circuit Factories - 4 layer Taconic ENIG PCB 53 – Huihe
About PTFE PCB PTFE (commonly known as Teflon) is an ideal dielectric for RF applications, but it is not easily compatible with the conventional dielectric FR4 in PCB manufacturing. Ceramic dielectric is the most commonly used dielectric material in multilayer PCB. It can be used as a separate dielectric layer in special applications and as an inner dielectric layer in FR4 laminated structure in conventional applications. Many RF signal layers of RF design have large non copper filled ar... -
