Maintain consistent mechanical fastening and optimize heat-transfer performance between microprocessor and heat sink assemblies. Southco 5T Heat Sink Screws are designed to compensate for less-than-perfect alignment between microprocessor and circuit board and to allow for thermal expansion. FEATURES AND BENEFITS 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
