Metal Based High Frequency PCB Built on 3.0mm PTFE 1.0oz with Immersion Gold for Radio Device
(PCB's are custom-made products, the picture and parameters shown are just for reference)
Metal based substrate is a combination of metal based high frequency materials. The intermediate medium is made of high frequency materials (such as PTFE and others), one side is coated with copper foil, the other side is coated with copper base or aluminum base. The PCB made on this kind of modified material, we can call it metal based high frequency PCB.
