What is a Metal Core PCB ?

Metal core aluminum PCB is an aluminum-based copper clad laminate with good heat dissipation function. Generally, the single layer aluminum-based PCB is composed of a three-layer structure, which is a circuit layer (copper foil), an insulating layer and a metal base layer. Also used for high-end use is designed as a double sided and multilayer aluminum PCB.

A metal core PCB is a special PCB having a metallic base layer. This base layer is usually made of aluminum or copper. As it contains a metallic layer, it is named Metal Core PCB (MCPCB).

An aluminum PCB is a printed circuit board that contains a thin layer of conductive dielectric material. They are also called aluminum cladding, aluminum base, MCPCB (metal clad printed circuit board), IMS (insulated metal substrate), thermal conductive PCB, etc. Aluminum PCBs were developed in the 1970s, and soon their applications increased sharply. The first application is their use in amplifying hybrid integrated circuits. They are being used on a large scale, so we must understand aluminum PCB and its importance.

The metallic layer present in the metal core PCB does many wonders along with the dielectric layers. These PCBs are far better than FR-4 PCBs in terms of bearing thermal and pressure stresses. They are suitable for extreme conditions and high heat-dissipating components. Therefore, it has solved many issues that were faced in other PCB substrates. Metal core PCBs have tons of benefits, but all of them come at an additional cost.

What is IMS Circuit board ?

Insulated Metal Substrate (IMS)

The use of IMS circuit boards for simple single-layer circuits is a special but very effective method of heat dissipation for components across circuit boards. These generally consist of aluminium supports, insulation layers and copper foil. The base materials are available in different design versions.

Aluminum pcb Applications:

LED technology: Illuminated signs, displays and lighting

Automotive industry: LED headlights, engine control and power steering

Power electronics: DC power supply, inverters and engine control

Switches and semi-conductor relays

Aluminum pcb Manufacturing process

The metal core PCB fabrication process is ①Grinding plate (500# brush)→②Washing→③Passivation→④Washing×3→⑤Blow-drying→⑥Drying. Grinding plate: Grinding the iron surface only, grinding the plate according to FR4 parameters.

Metal core PCBs must follow a particular process due to the presence of the metal layer in the stackup. If the board is a single-layer board with no layer transitions back to the metal plate, then the standard FR4 dielectrics can be used, where the dielectric layer is pressed and bonded to the metal plate.

For multilayer dielectric stackups, the metal core must first be drilled to allow for a layer transition without creating a short circuit. First, slightly larger holes are drilled into the metal layer, and the holes are plugged with an insulating gel. This gel is cured and hardened, allowing it to be plated with copper, just like a standard via. The rest of the stackup is pressed and bonded with the metal layer, and through-holes are drilled through the stackup, followed by plating and cleaning.

The first board must check the circuit without scratches, black tin surface, other defects, and uniform wear marks.
