ZF Electronics, as one of the top printed circuit board maker in China, can provide customers with single-sided PCB, double-sided FR4 PCB, metal core PCB, heavy copper PCB, rigid PCB and rigid-flex PCB. It provide pcb board, single layer pcb, multi layer board, rigid flex pcb, aluminum pcb,etc.

 

Metal core PCB China (printed circuit board), also known as MCPCB board, insulated metal substrate (IMS) or heat dissipation PCBS, is one of the most widely used PCBs today. These PCBs have applications in various industrial electronic equipment. There may be some problems that how these PCBs differ from regular PCBs and what their advantages over standard CEM3 or FR4 PCB are. This mcpcb factory provide metal pcb board and metal backed pcb,etc.

The metal base pcb produced by ZF, a professional metal core PCB manufacturer and PCB assembly company, has different layers. The basic material used in metal core PCB is metal, not FR4 or CEM3. The most commonly used metals are aluminum which is cheap and has good heat dissipation and transmission capabilities, steel alloys which are harder than the other two with low thermal conductivity, and copper which has better heat dissipation and transmission capabilities than aluminum and stainless steel, but are expensive. Therefore, the choice about what kind of metal cores should be used will depend on the application where they are used.

 

Types of metal core PCB

 

According to the position of the metal core and the wiring layer, it can be divided into four basic types, including:

 

Single-layer MPCB: PCB with a single wiring layer on one side.

Double-layer MPCB: PCB with two wiring layers on the same side.

Double-sided MPCB: there are two wiring layers on each side of these PCBs.

Multilayer MPCB: each of these PCBs has more than two layers.

Power equipment: DC-DC converters, voltage regulators, high-density power conversion, and switching regulators.

 

Audio equipment: balance, input and output, audio, power supply, and pre-shielding amplifier.

 

Other electronic equipment: IC array, semiconductor heat shield, IC carrier chip, solar cell substrate, radiator, and semiconductor refrigeration equipment.

 

Household appliances: flat panel displays, motor controls.

 

OA equipment: large electronic display substrate, thermal print head, and printer driver.

 

Advantages of MCPCB

 

The following advantages of metal core PCB make it an ideal choice for different industrial applications.

 

High thermal conductivity:

 

Standard PCB with FR4 and CEM3 has weaker interlayer insulation and lower thermal conductivity. Without proper heat dissipation, the internal temperature may rise to affect internal components. However, the metal PCB made of aluminum has excellent thermal conductivity to solve the problems above to keep the internal safe.

 

Good dimensional stability:

 

Metal core PCB shows good dimensional stability compared with FR4 or CEM3 PCB. When the aluminum PCB is heated to a temperature of 30℃ to 140~150℃, its size will only expand between 2.5-3%.

 

High thermal expansion:

 

The coefficient of thermal expansion (CTE) is a term to describe the expansion or contraction of a substance under temperature. The CTE of aluminum and copper is higher than that of ordinary FR4 while its thermal conductivity is 0.8~3.0 W/cK.
