Aluminum plate is a unique metal-based CCL (see chart structure), which has good thermal conductivity, electrical insulation and mechanical processing performance.

First, the characteristics of aluminum plate

● use of Surface Mount Technology (SMT);

● circuit in the design of the heat for the proliferation of highly effective treatment;

● lower operating temperature, increase the power density and reliability of the product, to extend the service life of the product;

● reduce the volume of products and reduce the cost of hardware and assembly;

● replace the fragile ceramic substrate, better mechanical endurance.

Second, the structure of the aluminum plate

Copper Clad Aluminum is a metal circuit board materials, copper foil, thermal insulation and metal composition of the substrate, and its three sub-structure:

Cireuitl.Layer-line: the equivalent of the common PCB CCL, the thickness of the copper lines loz to 10oz.

DielcctricLayer insulation layer: a layer of insulation is a low-resistance thermal insulation materials. Thickness: 0.003 "to 0.006" inch aluminum CCL is the core of the total operation is located, has been UL certification.

BaseLayer the grass-roots level: metal substrate, usually aluminum or copper can be chosen. CCL traditional aluminum and glass epoxy cloth laminate, and so on

Circuit level (that is, copper foil) are usually formed after etching printed circuit so that the various components parts to connect with each other, under normal circumstances, the circuit layer requires a lot of current-carrying capacity and thus should be used thick copper foil, the thickness of 35μm ~ 280μm; thermal insulation layer is the core technology of aluminum plate where it is usually filled by special ceramics of the special polymer composition, small thermal resistance, good viscoelastic properties, heat aging has the ability to withstand heat and mechanical stress . I have produced high-performance aluminum thermal insulation boards is the use of such technology, it has excellent thermal performance and high-intensity electrical insulation properties; metal aluminum plate is the grass-roots support components require high thermal conductivity Usually aluminum, copper can also use the (copper which can provide better thermal conductivity), suitable for drilling, cutting and punch, such as conventional machining.

PCB material compared to other materials have incomparable advantages. Power components for surface mount SMT public art.

No radiator, greatly reduce the size, excellent cooling effect, good insulation and mechanical properties.

Third, the use of aluminum plate:

Uses: Hybrid-power IC (HIC).

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

2. Power Equipment: switching regulator `DC / AC converter such as` SW regulator.

3. Electronic communications equipment: an increase of high-frequency electrical device `filter` transmitter circuit.

4. Office automation equipment: motor drive, and so on.

5. Vehicle: electronic ignition regulator `` power controller, and so on.

6. Computer: CPU board `` floppy disk drive power supply and so on.

7. Power Modules: converter `solid` relay power rectifier bridges.
