Product Details

1 Definition

The aluminum board is a metal-based copper-clad laminate with good heat dissipation. Generally, a single-sided panel consists of a three-layer structure, which is a circuit layer (copper foil), an insulation layer, and a metal substrate. For high-end use is also designed as a double-sided board, the structure of the circuit layer, insulation layer, aluminum, insulation, circuit layer. A very small number of applications are multilayer boards, which can be made of ordinary multilayer boards with insulating layers and aluminum printed circuit board.


LED aluminum board is the PCB, but also the meaning of the printed circuit board, but the material of the circuit board is aluminum alloy. In the past, the material of the general circuit board is glass fiber, but because the LED heat is larger, the circuit board used for LED lamps is generally Aluminum board, able to heat fast, other equipment or electrical appliances used in the circuit board or fiberglass board!


2 working principle edit

The power device is surface mounted on the circuit layer. The heat generated during the operation of the device is quickly conducted to the metal substrate through the insulating layer, and then the heat is transferred from the metal substrate to heat the device (see Figure 2).


Compared with the traditional FR-4, the aluminum board can reduce the thermal resistance to the lowest, so that the aluminum board has excellent thermal conductivity; compared with the thick-film ceramic circuit, its mechanical properties are extremely good.


In addition, the aluminum board has the following unique advantages:


Ø Meet RoHs requirements;


Ø More adaptable to SMT process;


Ø In the circuit design scheme, the thermal diffusion is processed extremely efficiently, thereby reducing the module operating temperature, prolonging the service life, and increasing the power density and reliability;


Ø Reduce the assembly of radiators and other hardware (including thermal interface materials), reduce product size, reduce hardware and assembly costs; Ø Optimize the combination of power circuits and control circuits;


Ø Replace brittle ceramic board for better mechanical durability.

Features

Aluminum board (metal-based heat sinks (including aluminum, copper, and iron substrates)) are low-alloy Al-Mg-Si based high-plasticity alloys (structures shown in the figure below) that have good thermal conductivity and electrical insulation. Performance and machinability, compared with the traditional FR-4 aluminum substrate, using the same thickness, the same line width, aluminum substrate can carry higher current, aluminum substrate pressure up to 4500V, thermal conductivity greater than 2.0, in The industry mainly uses aluminum substrates.


● Use surface mount technology (SMT); ● Perform extremely effective thermal diffusion in circuit design solutions;


● Reduce product operating temperature, increase product power density and reliability, and extend product life;


● Reduce product size, reduce hardware and assembly costs;


● Replaces brittle ceramic substrates for better mechanical durability. structure


Aluminum-based copper clad laminate 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:


Cireuitl.Layer circuit layer: equivalent to ordinary PCB copper clad laminates, the thickness of the line copper foil loz to 10oz.


Aluminium pcb are widely used in LED lighting with good thermal conductivities. We provide great material with high thermal conductivities to make sure stable and long life for the led product and power supplier project.
