Aluminum plate, aluminum matrix circuit board, and high conductivity aluminum plate aluminum plate is a unique metal-clad aluminum plate, it has good thermal conductivity, electrical insulation performance and mechanical processing performance. 　　
        First, the characteristics of aluminum substrate
● Surface mount technology (SMT); in circuit design for thermal diffusion is extremely effective management; reduce product operating temperature, improve product power density and reliability, long product life; reduce product size, reduce hardware and Assembly costs; replace fragile ceramic substrate, better mechanical durability. 　　
         Second, the structure of aluminum substrate aluminum matrix CCL is a metal circuit board materials, copper foil, thermal insulation and metal substrate composition, its structure is divided into three layers: Cireuitl.Layer line: correspond to normal PCB CCL, line copper foil thickness loz to 10oz. 　　DielcctricLayer insulation: the insulating layer is a layer of heat-insulation materials with low thermal resistance. Thickness: 0.003 "to 0.006" inches is aluminum matrix CCL's core meter operation, has been awarded a UL. 　　BaseLayer Base: is the metal substrate, typically aluminum or copper can be selected. Aluminum-clad and traditional epoxy-glass laminates such as circuit-layer (that is, copper foil) usually after etching formation printed circuit, the component parts are connected to each other, in General, circuit-layer requires a lot of current-carrying capacity, so you should use a thicker copper foil, thickness General 35 μ m ~ 280 m; thermal insulation, μ is the aluminum plate where the core technology, it is normally provided by special ceramic-filled special polymer composition, thermal resistance, excellent viscoelasticity, heat aging resistance, able to withstand the mechanical and thermal stress. The company is a manufacturer of high performance aluminum plate of thermal insulation is using this technology, so that it has very good thermal conductivity and high intensity of electrical insulation performance; metal base is aluminum plate support component, require a high thermal conductivity, typically aluminum sheet, you can also use copper plate (where copper can provide better thermal conductivity), suitable for drilling, cutting, punching and conventional mechanical processing. 　　PCB materials compared with other materials incomparable advantages. Suitable for surface-mount power components SMT public art. 　　Without heatsink, the volume is greatly reduced, thermal effect is extremely good, good insulation properties and mechanical properties. 　　
        Third, the aluminum plate uses: use: power hybrid IC (HIC). 　　1. audio device: input, output amplifier, balanced, amplifiers, audio amplifiers, preamplifiers, power amplifiers, etc. 　　2. the power supply: switching regulator ` DC/AC converters ` SW regulator, etc. 　　3. the communication electronics devices: high-frequency boost ` filtering appliances ` radio circuit. 　　4. the Office automation equipment: motor drive, etc. 　　5. vehicles: electronic regulator ` igniter ` power supply controllers, and so on. 　　6. computer: the CPU board ` ` power supply unit for the floppy disk drive. 　　7. power module: convectors ` solid state relay ` bridge, etc.　　8. lighting: with energy-saving lamps of various energy-saving promotion, advocating the gorgeous led market, and applied to the led lighting of the aluminum plate also began large scale applications.
