The aluminum-based circuit board is made of PCB circuit board. PCB aluminum plate is a unique metal-based CCL, PCB aluminum plate has good thermal conductivity, electrical insulation properties and mechanical processing performance.

Features

● PCB aluminum substrate surface with mounting technology (SMT); PCB aluminum plate in the circuit design program has a good heat dissipation;

● PCB aluminum plate can reduce the temperature, improve product power density and reliability, extend product life;

● PCB aluminum plate can reduce the size, reduce hardware and assembly costs;

● PCB aluminum plate can replace the ceramic substrate, get better mechanical endurance.

Structure

PCB aluminum clad copper plate is a kind of metal circuit board material, composed of copper foil, thermal insulation layer and metal substrate, its structure is divided into three layers:

Line layer: equivalent to ordinary PCB CCL, line copper foil thickness loz to 10oz.

Insulation: Insulation is a layer of low thermal resistance thermal insulation material. Thickness: 0.003 "to 0.006" inches is the core of aluminum-based CCL, where UL certification has been obtained.

Base: metal substrate, usually aluminum or copper can be selected. Aluminum-based CCL and the traditional epoxy glass cloth laminates and so on

PCB layer is composed of circuit layer, thermal insulation layer and metal base layer; circuit layer (ie copper foil) is usually etched to form a printed circuit, so that the components of the various components connected to each other, under normal circumstances, the circuit layer requires a large current Capacity, which should be used thicker copper foil, the thickness of the general 35μm ~ 280μm;

Thermal insulation layer is the core technology of PCB aluminum substrate, which is generally made of special ceramic filled with special polymer, thermal resistance, viscoelastic performance, with the ability of heat aging, able to withstand mechanical and thermal stress. IMS-H01, IMS-H02 and LED-0601 and other high-performance PCB aluminum substrate thermal insulation layer is the use of this technology, it has a very good thermal conductivity and high strength electrical insulation performance;

The metal substrate is a support member of an aluminum substrate, which requires a high thermal conductivity, generally an aluminum plate, or a copper plate (in which the copper plate can provide better thermal conductivity), suitable for conventional machining such as drilling, punching and cutting. PCB material compared with other materials have incomparable advantages. Suitable for power components surface mount SMT art. No need for radiator, greatly reduced size, excellent heat dissipation, good insulation and mechanical properties.
