Aluminum PCB/Metal Core PCB/MCPCB/Insulated Metal Substrate(IMS)

Insulated metal substrate (IMS consists of a metal baseplate (Aluminum is commonly used because of its low cost and density) covered by a thin layer of dielectric (usually an epoxy-based layer) and a layer of copper(35um to more than 200um thick).

The FR-4 based dielectric is usually think (about 100um).

Compared to a classical printed circuit board, the IMS/MCPCB provides a better heat dissipation.

It is one of the simplest way to provide efficient cooling to surface mount components.

Among all Metal core PCBs, Aluminum MCPCBs are the most common type-the base material consists of aluminum core with standard FR4 - It features a thermal metal-clad layer that dissipates heat in a highly efficient manner, while cooling components and increasing the overall performance of the products.

Currently, Aluminum-backed PCBs are regarded as the solution to high power and tight tolerance applications.

MKTPCB has been offering Aluminum PCB manufacturing services for over ten years.

Our full-feature Aluminum circuit boards making capabilities and value-added options including Free DFM Check allow you to get high-quality Aluminum PCBs done within budget.

Aluminum PCBs fabricated by us are widely used for LED lighting, Power equipment and Automotive systems.

Metal Core PCB Materials and Thickness

The metal core of the thermal PCB can be :

1) Aluminum (aluminum core PCB), 2) Copper (copper core PCB or a heavy copper PCB)

or a mixture of special alloys, while the most common being Aluminum core PCB.

The thickness of metal cores in PCB base plates is typically 30 mil - 125 mil, but thicker and thinner plates are also available.

MCPCB copper foil thickness can be 1 - 10 oz.

MKTPCB Aluminum PCB Capacity :

MKTPCB can produce 1-Layer, 2-Layer, 4-Layer and 6-Layer Aluminum PCBs.

Multilayer aluminum PCB is mainly used by high power Industrial products, like outdoor Led screens.

Solder mask Color: White, Black.

We can also provide Super-White color for LED PCB to improve the reflected light off of the board to increase the Lumens.
