The standard 4L layers stackup is the most common option selected by PCB designers. The standard layer stackup can be utilized in most applications.
As a standard option, you can get a variable layer stack up from us, which is defined by following:
PCB thickness: 0.5mm/0.8mm/1.0mm/1.6mm/2.0mm/2.5mm/3.0mm
Final finsihed copper thickness: 1/1/1/1oz (Note: the out layer copper thickness below is base copper thickness)
Above stack up is our standard 4L layer buildup that upon best manfuacturing features: such as below for finished thickness 1.60mm with 2/2/2/2 oz 4L PCB stack up,option 1 is not good as option 2 ( preprege 1080 in option 2 has more glue than 7268 in option 1):
Above stack up is our standard 4L layer buildup with 2/2/2/2 oz final finished copper thickness that already upon best manufacturing features for multilayer PCB.
