What is a Copper Base PCB
The copper base PCB is mainly based on copper, and its composition structure are the same as that of the aluminum PCB , which are the copper base layer, the insulating layer and the circuit layer. 1. The circuit layer of the copper base PCB is required to have a large current carrying capacity, so thicker copper foil should be used. 2. The insulating layer is the core technology of the copper base PCB. The composition is composed of aluminum oxide and silicon powder and epoxy resin filled polymer. It has low thermal resistance, excellent viscoelasticity, thermal aging resistance, and can withstand mechanical and thermal stress. 3. The metal base layer is the support member of the copper base PCB, which requires high thermal conductivity and is suitable for conventional machining such as drilling, punching and cutting. 4. Copper base PCB can b...
