Dear all customers, Kindly reminding that the Chinese festival holiday in Weller is 1st Feb to 19th Feb and production will be closed then, please schedule your order beforehand to avoid any production delay due to our holiday.

Standard 16 layer PCB stackup options

Our standard 16L layers stackup is the most common options selected by most PCB designers. The standard 16 layer stackup can be utilized in most applications for multilayer PCB board.

As the standard options, you can get a variable 16 layer stack up from Weller’s engineering suggestion, which is defined by following with 3 options :

PCB thickness: 2.2mm/2.5mm/3.0mm
Copper thickness:1/1/1/1/1//1/1/1/1/1/1/1/1/1/1/oz
Base material:Tg170 (Recommend)
RemarkThe Prepreg thickness could be adjusted according to track distribution
Option 1: Standard 16L PCB stack up 2.2mm
Option 2: Standard 16L PCB stack up 2.50mm
Option 3: Standard 16L PCB stack up 3.0mm

Above stack up is our 3 options of standard 16L layer PCB buildup that upon the best manfuacturing features(quality and price).

We recommend PCB designers to use Tg170 laminate material for multilayer PCB (>= 6 layers) to avoid any potential quality problem during your PCB assembly process: such as layers delamination,blister in lead free assembly process,etc.

Above stack up options is our standard 16L layer buildup with 1/1/1/1/1/1/1/1/1/1/1/1/1/1/1/1 oz finished copper thickness that the upon best manufacturing features for multilayer rigid PCB.

If you need custom stack up or stack up with impedance control for 16L circuit board,or you need 2oz or upper copper thickness PCB stack up, you can send your request to
