Standard 6L PCB Stack-up Design Reference

The standard 6L layers PCB stack-up is the most common options selected by PCB designers. The standard layer stack-up can be utilized in most applications.

As a standard option, you can get a variable 6 layer stack-up from us, which is defined by following:

Prepreg: All the preprge selection refer S1000HB

Base material:: Tg>=150 (Strongly recommend)

PCB thickness: 0.7mm/0.8mm/1.0mm/1.6mm/2.0mm/2.4mm/3.0mm

Final finished copper thickness: 1/1/1/1/1/1oz (Note: the out layer copper thickness: base copper+plating copper)

Above stack up is our standard 6L layer PCB buildup with with 1/1/1/1/1/1 oz  final finished copper thickness  that upon the best manufacturing features (reliability, performance, and production cost). We recommend to use Tg150 for multi-layer PCB more than 4 layers to avoid any potential quality problem during your PCB assembly process: such as de-lamination, blister, etc, in high temperature of lead-free assembly process.

If you need a customized Multi-layer PCB stack-up or any stack up with impedance control, or you need 2oz or upper copper thickness PCB stack up, you can send your request to service@wellerpcb.com. Our engineer will have a professional response with 2-4 hours.
