Metal Based High Frequency PCB Built on Modified Woven Fabric Glass Teflon (PTFE) Copper Clad Laminates with Ceramic Filler
(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.
