Speedstack templates

Speedstack stackup templates (suitable for Speedstack 2019 or higher)

The industry standard Speedstack PCB stackup design & documentation tool suite offers a powerful solution for PCB fabricators and designers for planning and creating live stacks (buildups) – complete with controlled impedance and insertion loss information and professional high quality documentation.

The stackup templates listed below are typical of standard stacks used in PCB construction and may prove a useful starting point when building your own stacks.

Click on the link to the stackup template page and download the Speedstack project (.sci) file; save to a convenient location and the use the Open Project command in Speedstack to view and edit the stackup

 

Stackups

Stackups are shown with dimensions in microns

Stackup Description Template

6 layer rigid stackup with mechanical drill between layers 1 and 6. This is a typical foil build with foils on the outers (more cost effective than core builds – except in RF applications)

8 layer rigid stackup with mechanical drill between layers 1 and 8 and laser drills between layers 1 and 2 and layers 8 and 7

8 layer rigid template

6 layer core build rigid stackup – layers 1 and 6 single sided cores

4 layer RF core build rigid stackup – Material Library mode. Core builds are often used for RF applications allowing the use of high performance materials on outers with lower cost materials internally.

4 layer RF core build rigid stackup – Virtual Library mode. Virtual library mode allows designers to give fabricators a general specification – whilst allowing the fabricator freedom in final material selection.

Stackup Description Template

4 layer flex rigid – this shows a board with three cross sections, however Speedstack Flex permits unlimited cross sections for the most demanding rigid flex designs.
