With the continuous development and progress of modern electronic product technology, electronic products are gradually developing towards light, thin, small, personalized, high-reliability, and multi-functionality. Aluminum substrates were born in accordance with this trend. Aluminum substrates have been widely used in hybrid integrated circuits, automobiles, office automation, high-power electrical equipment, power supply equipment and other fields with excellent heat dissipation, good machinability, dimensional stability and electrical performance. use.

　　 Aluminum substrate process flow

　　 Cutting → drilling → dry film light imaging → inspection board → etching → corrosion inspection → green oil → character → green inspection → spray tin → aluminum base surface treatment → punching → final inspection → packaging → shipment

　　Aluminum substrate precautions

　　 1. Because the price of raw materials is relatively high, pay attention to the standardization of operations during the production process to prevent losses and waste caused by errors in production operations.

　　 2. The surface of the aluminum substrate is poor in wear resistance. The operators of each process should wear gloves when operating, and handle with care to avoid scratches on the board surface and aluminum base surface.

　　3. For all manual operations, gloves should be worn to avoid touching the effective area of the aluminum substrate with your hands to ensure the stability of the subsequent construction operations.
