MetalcorePCB is widely used because of its excellent heat dissipation, dimensional stability, good signal transmission and easy processing.If your product has heat dissipation requirements, the first choice is metal core PCB.

Metal Core PCB

Excellent Heat Dissipation：

Thermal conductivity refers to the thermal performance parameter of a material.Many high-power, high-density CEM3 or FR4 PCBs face heat dissipation difficulties, and metal core PCBs such as aluminum PCBs can solve this problem well.High thermal conductivity enables metal core PCBs to have excellent interlayer insulation and thermal conductivity, 8-9 times higher than standard FR4 PCB thermal conductivity.The heat generated by the IC Package and components will be quickly taken away, which is beneficial to reduce the thermal damage of the components, prolong the service life of the product, and improve the product performance.

The direction of miniaturization, light weight, multi-function and high performance.Therefore, the problem of heat dissipation has become an important issue affecting the stability and reliability of electronic products.Metal core PCB is an effective way to solve the heat dissipation problem of high density circuit when customers are doing PCB assembly prototype and mass production.

High strength, Long life:

The material strength of the metal core is incomparable with epoxy resin materials.Especially the aluminum-based PCB greatly improves the strength of the circuit board on the basis of ensuring light weight.It can effectively reduce the risk of breakage that may occur during production, assembly and product use.Improve the life of the printed circuit board.

Excellent Dimensional Stability:

Aluminum PCBs and copper PCBs have a high CTE (Coefficient of Thermal Expansion).The ability to contract cold and expand thermally is called the coefficient of thermal expansion.Most FR4 PCBs have a low CTE, which means they cannot handle shrinkage and expansion effectively.However, both metal core PCBs can effectively handle thermal expansion, and the board size does not change much compared to ordinary FR4 at high temperatures.The dimensional change range under high temperature conditions is about 2.5%.

Excellent Signal Transmission：

PCBmanufacturer talk good heat dissipation of metal core PCBs makes them less prone to high temperature, which causes less distortion during signal transportation.

Environmentally friendly recyclability:

The metals used in metal core circuit boards (aluminum, copper, steel) are easy to recycle and the production process is non-toxic.The damage level is low in the entire ecological chain.

Cost-effectiveness:

 affordable raw material purchase prices reduce overall PCB manufacturing costs due to the lower cost of mining and refining aluminum.

The aluminum PCB has excellent thermal conductivity performance, suitable for products with large heat dissipation requirements.JHDPCB can produce aluminum PCB with thermal conductivity up to 10W/m.k.
