Aluminum Metal Core PCB for Led lighting with high-thermal conductivity
Aluminum Metal Core PCB for Led lighting with high-thermal conductivity
Aluminum substrate is a metal-based copper-clad laminate with good heat dissipation function. Generally, a single panel is composed of three layers: circuit layer (copper foil), insulation layer, and metal substrate. Commonly seen in LED lighting products. There are two sides, the white side is for soldering LED pins, and the other side presents the natural color of aluminum, usually coated with thermal conductive paste and in contact with the thermal conductive part. There are also ceramic substrates and so on.
LED aluminum substrate refers to PCB, which also means printed circuit board. However, the material of the circuit board is aluminum alloy. Previously, the material of our general circuit board was fiberglass, but because LED generates a lot of heat, the circuit board used for LED lamps is usually aluminum substrate, which can conduct heat quickly. The circuit board used for other equipment or electrical appliances is still fiberglass board.
Aluminum substrate (metal-based heat dissipation plate (including aluminum substrate, copper substrate, and iron-based plate) is a low-alloy Al Mg Si high plasticity alloy plate (structure shown in the figure below), which has good thermal conductivity, electrical insulation performance, and mechanical processing performance. Compared with traditional FR-4, aluminum substrate can carry higher current with the same thickness and line width. The withstand voltage of aluminum substrate can reach 4500V, and the thermal conductivity coefficient is greater than 2.0. Aluminum substrate is mainly used in the industry.
It has following characteristics.
Adopting surface mount technology (SMT).
Efficient treatment of thermal diffusion in circuit design schemes.
Reduce product operating temperature, improve product power density and reliability, and extend product service life.
Reduce product size, lower hardware and assembly costs.
Replace fragile ceramic substrates for better mechanical durability. Structure.
Application of aluminum substrate: power hybrid IC (HIC).
Audio equipment
Input and output amplifiers, balanced amplifiers, audio amplifiers, preamplifiers, power amplifiers, etc. [2]
Power supply equipment
