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, 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
Copper thickness: 1/1/1/1oz
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 1/1/1/1 oz finished copper thickness that already upon best manufacturing features for multilayer PCB.
If you need custom stack up or stack up with impedance control,or you need 2oz or upper copper thickness PCB stack up, you can send your request to firstname.lastname@example.org.
