Advantages of Aluminum PCBs

  • Low Cost-Aluminum is a metal that can be found in a variety of climates, so it is easy to mine and refine. 


  • Environmentally Friendly-Aluminum is non-toxic and recyclable. Manufacturing with aluminum is also conducive to conserving energy due to its ease of assembly. 


  • Heat Dissipation-Aluminum can actually transfer heat away from vital components, thus minimizing the harmful effect it could have on the circuit board.


  • Higher Durability-Aluminum provides strength and durability to a product, also it is a sturdy base material that can reduce accidental breakage during manufacturing, handling, and everyday use.


  • Lightweight-Aluminum is a surprisingly lightweight metal. Aluminum adds strength and resilience without adding on any additional weight.

Aluminum PCBs Introduction


-Definition

Aluminum base is a CCL, a type of base material of PCBs. It 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.


Why is Aluminum used in LED light?


-Aluminum can actually transfer heat away from vital components, thus minimizing the harmful effect it could have on the circuit board.


-The intense light produced by LEDs creates high levels of heat, which aluminum directs away from components. An aluminum PCB extends the lifespan of an LED device and provides more stability.

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.
