Manufacturing Difficulties of Aluminum PCBs:
The manufacturing process for nearly all-aluminum PCBs is basically
the same. Here we will discuss the main manufacturing processes,
the problems and their solutions.
1: Copper Etching
The copper foil used in Aluminum PCBs is moderately thicker. If the
copper foil is over 3-oz however, the etching requires width
settlement. If it is not according to the demand of the design, the
trace width will be out of tolerance after etching. That is why the
trace width compensation should be designed accurately. The etching
factors need to be controlled during the manufacturing process.
2: Solder Mask Printing
Due to 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 base board and trace surface and solder mask printing will
be quite difficult. Therefore, the two-time solder mask printing is
preferably used. The solder mask oil used should be of decent
quality and in some cases, the resin filling is done first and then
solder mask
3: Mechanical Manufacturing:
The mechanical manufacturing process involves molding, mechanical
drilling, and v-scoring, etc. Which is left on internal via. This
tends to decrease electrical strength. Therefore, the professional
milling cutter and electric milling cutter should be used for
low-volume manufacturing of products. The drilling parameters
should be adjusted to prevent burr from generating. This will help
your mechanical manufacturing.
