Commonly used aluminum industrial materials

Aluminum plate

Aluminum substrate is a common metal base copper clad aluminum substrate, it has a good thermal conductivity, electrical insulation properties and machining properties.

First, the characteristics of aluminum substrate

● using surface mount technology (SMT)

● Extremely efficient thermal diffusion in circuit design

● reduce product operating temperature, improve product power density and reliability, extend product life

● reduce product size, reduce hardware and assembly costs

● Replace the fragile ceramic substrate for better mechanical durability.

Second, the structure of the aluminum substrate

New high-electronic aluminum clad laminate is a kind of metal circuit board material, which consists of copper foil, thermal insulation layer and metal substrate. Its structure is divided into three layers:

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

DielcctricLayer Insulation: Insulation is a layer of low thermal conductivity of thermal insulation materials. Thickness: 0.003 "to 0.006" inches is the core of aluminum-based CCL, which has obtained UL certification.

BaseLayer grassroots: is a metal substrate, usually aluminum or copper of choice. CCL and traditional epoxy glass cloth laminate and so on

The circuit layer (ie, copper foil) is typically etched to form a printed circuit that interconnects the various components of the module. In general, the circuit layer requires a large current carrying capacity, so thicker copper foil should be used with a typical thickness of 35 m ~ 280 m; thermal insulation layer is the core technology of aluminum substrate, which is generally composed of special ceramic filled with a special polymer composition, thermal resistance, viscoelastic performance 俍, with heat aging ability to withstand mechanical and Thermal Stress. The company's high-performance thermal conductivity of the aluminum substrate is the use of this technology to make it has excellent thermal conductivity and high electrical insulation properties; metal substrate is the aluminum substrate support member requires a high thermal conductivity Generally, aluminum, but also copper (copper can provide better thermal conductivity), suitable for drilling, punching and cutting and other conventional machining.

PCB materials compared to other materials have incomparable strengths. Suitable for power components SMT surface art.

No radiator, volume is greatly reduced, the cooling effect is excellent, 俍 good insulation and mechanical properties.

Third, the new high use of aluminum substrate:

Uses: Power Hybrid IC (HIC).

1. Audio equipment: input, output amplifier, balanced amplifier, audio amplifier, preamplifier, power amplifier and so on.

2. Power supply: Switching regulator `DC / AC converter` SW regulator and so on.

3. Communication electronics: high-frequency amplifier `filter electrical` hair report circuit.

4. Office automation equipment: motor drives and so on.

5. Automotive: electronic regulator `igniter` power controller.

6. Computer: CPU board `floppy drive` power supply unit.

7. Power (gong lv) module: inverter `solid state relay` rectifier bridge.

8. Lighting lamps: With the promotion of energy-saving lamps to promote, all kinds of energy-saving LED lights greatly welcomed by the market, and used in LED light aluminum substrate has begun large-scale application.

Aluminum plate

Aluminum-plastic plate is made of a surface-treated and coated with a coating of aluminum as the surface, polyethylene, polypropylene plastic mixed as the core layer, after a series of processing and processing of new composite materials. As the aluminum-plastic plate is composed of two different materials (metal and non-metal), which not only retains the main components of the original material (aluminum metal, non-metallic polyethylene plastic) the main features, but also to overcome the shortcomings of the original composition , And then get a number of excellent material properties, such as luxury, colorful and colorful decorative, weathering, corrosion resistance, hit a hit, fire, moisture, noise, heat insulation, seismic; Light, easy molding, easy handling Installation and other features, these features open up a broad use of aluminum-plastic plate prospects.

Aluminum-plastic panel performance: Super-stripping degree, material easily processed, fire performance, impact resistance, super weatherability, color diversity, easy maintenance.
