To ensure this stack (1st board + connector + 2nd board) is kept in place and to ensure the elec-
trical contact, one can simply use the following American Screw items:

• 2 US Screws UNC # 2 - 56, L = 10 mm
• 4 US Washers UNC # 2, isolating material
• 2 US Nuts UNC # 2 - 56

Optionally, one can use a specific mechanical kit in order to ensure a more efficient electrical
contact.

This mechanical kit consists mainly of a bolster plate and a connector holder assembled with
screws.

The following figures detail the kit’s elements and mechanical assembly.
