High thermal insulation materia LED lighting circuit boards

The heat dissipation problem of LEDs is the biggest headache for LED manufacturers, but aluminum substrates can be used. Because aluminum has high thermal conductivity and good heat dissipation, it can effectively extract internal heat. The aluminum substrate is a unique metal-based copper clad laminate with good thermal conductivity, electrical insulation properties and machinability. The PCB should also be placed close to the aluminum base as much as possible to reduce the Thermal Resistance generated by the potting compound.

The aluminum-based copper clad laminate is a metal circuit board material composed of a copper foil, a thermally conductive insulating layer and a metal substrate, and its structure is divided into three layers:
Circuit layer: equivalent to ordinary copper clad laminate board, line copper foil thickness loz to 10oz.
Insulation layer: The insulation is a low thermal resistance thermal insulation material.
Base Layer: It is a metal substrate, usually aluminum or copper. Aluminum-based copper clad laminates and conventional epoxy glass cloth laminates.

Aluminum circuit boards is a metal-based copper clad plate with good heat dissipation function. Generally, the single layer is composed of three-layer structure, which is a circuit layer (copper foil), an insulating layer and a metal base layer. Also used for high tech use is designed as double layers, the structure is circuit layer, insulation layer, aluminum base, insulation layer, circuit layer. A very small number of applications are multi-layer boards, which can be made of ordinary multi-layer boards combined with an insulating layer and an aluminum base.

Aluminum PCB characteristics
● Surface Mount Technology (SMT);
● Extremely efficient treatment of thermal diffusion in circuit design;
● Reduce product operating temperature, increase product power density and reliability, and extend product life;
● Reduce product size and reduce hardware and assembly costs;
● Replace the fragile ceramic substrate for better mechanical durability.

Aluminum PCB use:
● Audio equipment
Input, output amplifiers, balanced amplifiers, audio amplifiers, preamplifiers, power amplifiers, etc.
● Power supply equipment
Switching regulator, DC/AC converter, SW regulator, etc.
● Communication electronic equipment
