How should aluminum substrate manufacturers choose?

Aluminum substrate is a special kind of metal-based copper clad laminate, which is widely used because of its good thermal conductivity, heat dissipation, electrical insulation properties and machinability properties. **In the production process of road plate manufacturers, it can be clearly known that aluminum substrates can be divided into three layers, namely circuit layer (copper foil), insulation layer and metal base layer. Aluminum substrates are widely used in LED, air conditioning, automobiles, ovens, electronics, street lights, high power, etc.

Why aluminum substrates are so widely used and used in high-tech products. The thermal expansion, dimensional stability, heat dissipation and other properties of aluminum substrates make it meet more demanding products. At present, large and small aluminum substrate manufacturers are mixed, and the quality is uneven, how to choose a suitable aluminum substrate manufacturer.

It is particularly important to judge the quality of aluminum substrate manufacturers?

There are many factors that have to be considered, so please pay more attention to the following:

1. Process situation: see whether the factory can provide a process consistent with the design requirements, such as whether there is immersion gold process, lead spraying tin, etc., the quality of the process directly affects the performance of the circuit board.

2. Equipment: The yield rate of the model produced by advanced equipment is high, which not only ensures the quality, but also ensures the efficiency of delivery.

3. Delivery cycle: The delivery cycle is also an important factor to consider, there are many reasons for the delivery time, the most important of which is the factory's resource integration ability, high-quality aluminum substrate manufacturers will integrate the resources of all parties, so that the delivery speed can reach the fastest!

4. After-sales service: after the board is made, it is inevitable to encounter some problems in actual use, at this time intimate after-sales service is particularly important, the era of a hammer trading transaction has long passed, and the long stream of water is the current long-term way, at this time you can see whether the manufacturer has a sense of responsibility.

Aluminum substrates are mainly used in power hybrid ICs (HICs): audio equipment, power supply equipment, communication electronic equipment, office automation equipment, automobiles: electronic regulators, ignition, power controllers, etc.

Computer: CPU board, floppy disk drive, power supply unit, etc.

Power modules: inverters, solid relays, rectifier bridges, etc. Lamps and lanterns: aluminum substrates for LED lights.

Aluminum plate products, each manufacturer is different, it is recommended that the best field trip, good products have a good reputation!

Aluminum substrates can be divided into tin-sprayed aluminum substrates, anti-oxidation aluminum substrates, silver-plated aluminum substrates, immersion gold aluminum substrates, etc. According to the use, it can be divided into: street lamp aluminum substrate, fluorescent lamp aluminum substrate, LB aluminum substrate, COB aluminum substrate, encapsulation aluminum substrate, bulb aluminum substrate, power supply aluminum substrate, automotive aluminum substrate and so on.

The commonly used aluminum substrate plates mainly include 1000 series, 5000 series and 6000 series.
