Frequently Asked Questions

What makes metal-clad PCBs suitable for RF and microwave circuits?

Metal-clad PCBs use thermally conductive metal substrates — typically copper or aluminum — that efficiently dissipate heat generated in high-power RF and microwave circuits. They also provide excellent dimensional stability, reduced warpage, and superior electromagnetic shielding compared to standard FR4 boards, making them ideal for radar, wireless, and microwave systems.

What is the difference between copper core and aluminum base PCBs for RF applications?

What thermal conductivity levels are available in FX PCB's metal-clad PCBs?

What board thicknesses and copper weights are available?

Are metal-clad PCBs for RF circuits RoHS and REACH compliant?

What surface finish options are available for RF and microwave metal-clad PCBs?

Can FX PCB support both prototype and high-volume production of RF metal-clad PCBs?
