The aluminum substrate provides mechanical support for fixing and assembling various electronic components, integrated circuits, etc., and is an assembly board for achieving electrical connection between electronic components. Aluminum substrate is also called printed circuit board or printed aluminum-based circuit board, the English name is PCB. The aluminum substrate itself is an insulating substrate. There are component mounting holes, connecting wires (copper foil), and pads for assembling and soldering the pins of electronic components on the aluminum-based circuit board. One side of the aluminum substrate is used to mount electronic components, and the other side is used to solder component pins. A layer of insulating paint is often applied to the welding surface. The aluminum substrates produced by regular manufacturers have graphic symbols and numbers of electronic components on the front and back sides, but some aluminum substrates produced by manufacturers only provide graphic symbols and numbers on the component mounting surfaces.
The emergence of aluminum substrates has brought major changes to the electronics industry and greatly promoted the replacement of electronic products. Aluminum substrates have many unique functions and advantages, summarized in the following points.
①Electrical connection between various components in the circuit can be achieved instead of complicated wiring. The workload of wiring in the traditional way is reduced, and the assembly, welding and debugging of electronic products are simplified.
②Reduce the volume of the whole machine and reduce the cost of the product. Improve the quality and reliability of electronic equipment.
③ has a good consistency. It can use standardized design. It is beneficial to the mechanization of welding. Increased productivity.
④Aluminum substrate has better mechanical and electrical properties, so that electronic equipment can be combined into units, and the whole circuit board after assembly and debugging becomes a spare part, which is convenient for the exchange and maintenance of the whole product.
