FR4 PCB is made of epoxy resin plus filler (Filler) and glass fiber, it has good insulation, corrosion resistance, compression, multilayer printing and so on.It is widely used in communication, automobile, medical, industrial control, security and other fields.The glass fiber board is divided into half glass fiber board and full glass fiber board according to the material.
Aluminum substrate PCB(also MCPCB) is a kind of PCB, metal based printed board, with high thermal conductivity, good heat dissipation function.The general single layer MCPCB is composed of three layers of structure, which are the circuit layer (copper foil), the insulating layer and the metal base.Used for high-end use is also designed as a double-sided plate, the structure of the circuit layer, insulation layer, aluminum, insulation layer, circuit layer.Very few are used as multi-layer layer, which can be made up of ordinary multilayer with insulating layer and aluminum base.
The application field of aluminum substrate(MCPCB):
Price pricing for FR4 PCB and aluminum substrate PCB(MCPCB):
On the whole, the price of aluminum substrate PCB(MCPCB) is more expensive, and the aluminum substrate PCB(MCPCB) can not be plating through holes.
