I work for a PCBA subcon in the Philippines, and we are currently =
developing a project that would require using a very thin PCB. I would =
like to know the limitations of the HAL process, what minimum PCB =
thickness (FR4) can it handle? Is there any low-cost alternative process =
(other than bare copper) for surface treatment of such boards? Any help =
would be greatly appreciated.
