Aluminum PCBs Introduction


-Definition

Aluminum base is a CCL, a type of base material of PCBs. Aluminum core board is a composite material composed of copper foil, a dielectric layer, an aluminum base layer and aluminum base membrane with a good heat dissipation. Using a very thin layer of thermally conductive but electrically insulating dielectric, which is laminated between the metal base and the copper layer. The metal base is designed to draw heat away from the circuit through the thin dielectric.


-Application

aluminum pcb assembly's widely used for the modifier and sparker on fire for motorcycle and mobile, power LED, sound box, power supply module and acoustics shielding system etc.

How ABIS Working Out Manufacturing Difficulties of Aluminum PCB?


  • Raw materials are strictly controlled: The pass rate of incoming material above 99.9%. The number of mass rejection rates is below 0.01%.


  • Copper Etching Controlled: the copper foil used in Aluminum PCBs is comparatively thicker. If the copper foil is over 3oz however, the etching requires width compensation. With the high precision equipment imported from Germany, the min width/space we can control reaches 0.01mm. The trace width compensation will be designed accurately to avoid the trace width out of tolerance after etching.


  • High Quality Solder Mask Printing: As we all know, there is a difficulty in solder mask printing of aluminum PCB due to copper thick. This is because if the trace copper is too thick, then the image etched will have a large difference between trace surface and base board and solder mask printing will be difficult. We insist on the highest standards of solder mask oil in the whole process, from the one to the two-time solder mask printing.


  • Mechanical Manufacturing: To avoid reducing electrical strength caused by the mechanical manufacturing process, involves mechanical drilling, molding and v-scoring etc. Therefore, for low-volume manufacturing of products, we prioritize using the electric milling and professional milling cutter. Also, we pay high attention to adjusting the drilling parameters and preventing burr from generating.
