nanoSTAKE Design Guidelines

Download these guidelines.

Notes:

  • The recommended clearance hole diameter is 1.1D (1.25D is the maximum diameter)
  • The maximum recommended boss height above the mating surface is 1.5D
  • Add radius and chamfer to prevent A-surface sink and improve stake strength

The table below shows a range of possible boss dimensions that could be staked with the nanoSTAKE process. As a general rule, the punch volume is calculated to be 95% of the boss volume. This ensures the boss material fills and “packs out” the punch cavity. The maximum punch volume is 47.8 mm³.

NanoSTAKE modules are 8 mm in diameter at the tip.

Maintain 10 mm boss centerline spacing to allow for adjustment and variation.
