Features & Benefits
»
Quick Attachment – Push pins feature a flexible barb at the end designed to
engage with pre-drilled holes in a PCB.
»
Compression Springs add the necessary force to hold the assembly together
for secure attachment. Select from over 21 different springs to achieve
precise force required.
»
Push Pin Material available in brass or plastic in 10 sizes ranging from 9-
20mm in length. Stainless steel hardware kit available for more secure
attachment. Visit www.qats.com for available options.
»
Heat Sinks Designed for All Airflow Conditions. Select from over 112 fine
pitch HS designed for high velocity air flows and 98 course pitch HS
designed for low velocity air flow conditions.
»
Pre-assembled with phase-changing material for increased thermal
performance. Double-sided thermal tape and no TIM options available to
meet application-specific requirements.
»
Lightweight, aluminum HS extruded from AL6063 provide optimal heat
transfer with a blue anodized finish.
»
All components are RoHS and REACH compliant.
»
Industry standard hole pattern. Recommended through hole size is 3.175mm

1) Dimension A is the length of the heat sink in the direction of the flow.
2) Dimension B is the width of the heat sink perpendicular to the flow direction.
3) Dimension C is the heat sink height from the bottom of the base to the top of the fin
field.
4) Dimension E is the distance between holes perpendicular to the direction
of flow.
5) Dimension F is the distance between holes in the direction of flow.
6) Thermal performance data are provided for reference only. Actual performance may
vary by application.
7) ATS reserves the right tp update or change its products without notice
to improve the design or performance.
8) ATS certifies that this heat sink assemby is RoHS-6 and REACH compliant.
