Classification of Aluminum PCBs: Aluminum PCBs are essentially divided into three categories.
1: Universal Aluminum PCB: the dielectric layer used here is made up of epoxy glass fiber pre-preg.
2: High Thermal-Conductive Aluminum PCB:the dielectric layer is made up of epoxy resin. The resin used must have high thermal conductivity.
3: High-frequency Aluminum PCB:the dielectric layer is composed of polyolefin or polyimide resin glass fiber pre-preg.
Manufacturing Difficulties of Aluminum PCBs:
The manufacturing process for nearly all aluminum PCBs is essentially the same. Here we will discuss the major manufacturing processes, the difficulties and their solutions.
Copper Etching: the copper foil used in Aluminum PCBs is comparatively thicker. If the copper foil is over 3oz however, the etching requires width compensation. If it is not according to the demand of the design, the trace width will be out of tolerance after etching. Therefore the trace width compensation should be designed accurately. The etching factors need to be controlled during manufacturing process.
Solder Mask Printing: due to the thick copper foil there is a difficulty in solder mask printing of aluminum PCB. 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. Therefore, the two-time solder mask printing is used. The solder mask oil used should be of good quality and in some cases the resin filling is done first and then solder mask.
Mechanical Manufacturing: the mechanical manufacturing process involves mechanical drilling, molding and v-scoring etc. which Is left on internal via. This tends to reduce electrical strength. Therefore, the electric milling and professional milling cutter should be utilized for low-volume manufacturing of products. The drilling parameters should be adjusted to prevent burr from generating. This will help your mechanical manufacturing.
