Aluminum PCB prototyping method

Aluminum PCB prototyping refers to the process of printing, aluminum PCB manufacturers using the photographic method or electronic color separation machine made and made appropriate trimming negative, in mass production before a small number of prototyping. Here are a few ways to do aluminum PCB prototyping.

1. 1. Aluminum PCB board photographic material proof method

2. 2. Mechanical proofing method of aluminum PCB board

3. 3. Electronic proofing method of aluminum PCB board

4. 4. aluminum PCB board computer aided proofing method
   
   

Aluminum PCB prototyping process

Aluminum PCB prototyping technology should have rich process experience ability. Aluminum PCB with excellent heat dissipation, good machinability, dimensional stability and electrical performance, has been widely used in hybrid integrated circuits, automobiles, office automation, high-power electrical equipment, power equipment and other fields. The process of aluminum PCB prototyping and prototyping is from opening → drilling → dry film light imaging → inspection plate → etching → corrosion inspection → green oil → character → green inspection → spray tin → aluminum base processing → punching plate → final inspection → packaging → shipping end.

The composition of aluminum PCB board

As a kind of metal base copper-covered plate with good heat dissipation function, aluminum PCB board is divided into single panel and double panel. aluminum PCB board single panel is composed of circuit layer (copper foil), insulation layer and metal substrate. aluminum PCB board double panel is mainly used for high-end use.  The aluminum PCB board structure is composed of circuit layer, insulation layer, aluminum base, insulation layer, circuit layer. The thermal insulation layer of high performance aluminum PCB board ensures its excellent thermal conductivity and high strength electrical insulation performance.

Aluminum PCB board and PCB board difference

PCB board and aluminum PCB board are designed in accordance with the requirements of PCB board. PCB board is a big kind, aluminum PCB board is just a kind of PCB board, because of its good thermal conductivity, generally used in the LED industry. PCB board is copper base board, the material used between the two is a very obvious difference. The main material of aluminum PCB board is aluminum plate, and the main material of PCB board is copper. Because of the special PP material and better heat dissipation, aluminum PCB board is more expensive than PCB board.

Types of aluminum PCB board

The advantage of aluminum PCB board is that the heat dissipation is obviously better than the standard FR-4 structure, the dielectric used by aluminum PCB board is usually 5 to 10 times the thermal conductivity of conventional epoxy glass, and the heat transfer index is more efficient than the traditional rigid PCB board. The following are the types of aluminum PCB board.

1. 1. Flexible aluminum PCB board

2. 2. Mixed aluminum PCB board

3. 3. Multi-layer aluminum PCB board

4. 4. Through-hole aluminum PCB board
   
   

Selection method of aluminum pcb manufacturer

Because of the thermal expansion, dimensional stability, heat dissipation and other properties of aluminum PCB board, it can meet more high requirements of products. At present, the aluminum pcb manufacturers in the market are mixed and the quality is uneven. The following is about the method of selecting the appropriate aluminum pcb manufacturer.

1. 1. aluminum pcb manufacturer has reliable raw material quality.

2. 2. The delivery time of aluminum pcb manufacturers is fast, which can save the time cost of customers.

3. 3. Own aluminum pcb manufacturer base, dedicated line production

4. 4. aluminum pcb manufacturers have a good enterprise credit and reputation.

5. 5.  The aluminum pcb manufacturer has full experience of technical level

6. 6. The after-sales service quality of aluminum pcb manufacturers is good.
