Metal Core PCB manufacturing

Metal Core PCB(MCPCB) is that use metal as base material to fabricate PCB, we can use aluminum base, copper base and steel base to manufacture PCB but usually most MCPCB customes just need Aluminum core PCB and which are always used for LED, so we will show the Aluminum core PCB information but you can contact us for copper base PCB and steel base PCB if you really need them, we are always here for you.

Aluminum Core PCB

What's Aluminum Core PCB?

Aluminum plate with good heat dissipation function is a kind of metal base copper-clad r.p. panel and general single panel composed of three layers structure, respectively is the circuit layer (copper foil), insulation and metal base. For high-end use, also have a design for the panel for circuit layer, insulating layer, aluminum structure, insulation, circuit layer. Few applications for sandwich plate, can by ordinary sandwich plate with insulation layer, aluminum joint. LED aluminum plate is PCB, is also the meaning of printed circuit board, just PCB material is aluminium alloy, we used the general circuit board material is glass fiber, but because the LED heat is larger, so the LED lamps and lanterns with the circuit board is commonly aluminum plate, can fast heat conduction, other equipment or electrical circuit board or glass fiber board!

Aluminum PCB Structure

Circuit layer

Circuit  layer (generally using electrolytic copper foil) formed after etching printed circuit, used to implement the assembly and connection of the device. Compared with the traditional FR - 4, using the same thickness, the same line width, the aluminum plate can support higher current.

Dielectric layer

Dielectric layer is the most core technology of aluminum plate, the main adhesive, insulation and thermal conductivity of the function. Aluminum base board insulation layer is one of the largest thermal power module structure barrier. Insulation heat conduction performance, the better, the more conducive to the spread of the heat produced during the operation, will be conducive to reduce the operating temperature of the device, so as to improve the module of power load, reducing the volume and prolong life, improve the power output, etc.

Metal substrate layer

What metal insulated metal substrate, need to depend on the thermal expansion coefficient of metal substrate, heat conduction ability, strength, hardness, weight, surface state and cost conditions into account.In general, from conditions such as cost and technical performance, aluminum plate is ideal choice. Selection of aluminum plate, 6061505, 2106, etc. If there is a higher heat transfer performance, mechanical properties, electrical properties and other special performance requirements, copper, stainless steel plate, iron plate, silicon steel plate, etc. Can also be used
