Heat Sink Captive Screws

A captive spring-loaded design helps maintain a positive mechanical connection with a set preload, even under conditions of shock, vibration, and thermal expansion.

• Design adjusts to minor inconsistencies or non-planar condition between top surface of chip and PC board
• A positive stop sets the preload up to a maximum of 5 lbf.
• Captivated spring and screw prevent lost hardware or damage to circuit boards
• Flare in captivation style compatible with most heat sink materials from 1.5 mm (.058") to 3.2 mm (.126")
