YD5T - Heat Sink Captive Screws

Maintain consistent mechanical fastening and optimize heat-transfer performance between microprocessor and heat sink assemblies. Yaoda YD5T Heat Sink Screws are designed to compensate for less-than-perfect alignment between microprocessor and circuit board and to allow for thermal expansion.

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")

Available Options

• Multiple thread sizes – M3；M3.5；4-40；6-32

• Multiple screw lengths accommodate various standoff dimensions and PC board inserts

• Special installation tools are available for flaring standoffs. Order according to thread size
