Metal Based High Frequency PCB Aluminum Based Copper Based RF PCB Immersion Gold
(PCB's are custom-made products, the picture and parameters shown are just for reference)
Brief Introduction
Metal-based substrate is a combination of metal-based high-frequency materials. The intermediate part of it is composed of high-frequency materials like PTFE and others. On one side, it's coated with copper foil, while on the other side, there's a coating of either a copper base or an aluminum base, which serves the purposes of shielding or heat dissipation. The printed circuit board (PCB) fabricated using this kind of modified material is what we refer to as a metal-based high-frequency PCB.
Wangling’s series of high frequency materials, namely F4BM, F4BME, F4BTM, F4BTME, F4BTMS, provide us with aluminum base or copper base. The specific details are presented in the table below.
