Heat sinks are mounted directly to the board by a Z-Shaped Wire Clip, but only take up a minimum of board real estate. Attachment force and shock loads are transmitted to the PCB instead of the chip and solder balls. The compression load from the clip applies the appropriate mounting force for the heat sink and generates the pressure required for proper thermal interface material performance.
A minimum of 2 through holes are required in the board. The hole diameter must be 1.8mm(.071").
Mounting pins only require 1.8mm[.071"] diameter holes in the PCB.
Small footprint greatly reduces the amount of PCB space sacrificed for heat sink attachment, minimizing or eliminating the need to move board traces.
Heat sinks are mechanically attached to the PCB instead of the chip package or substrate.
Shock and vibration loads are transferred to the PCB
instead of the chip and solder balls.
Heat sink location and orientation is precisely set by anchor and pin. The possibility of damaging the chip, heat sink, or thermal interface material during installation is greatly reduced as well as the possibility of installing the heat sink in the wrong orientation or location.
Heat sink comes pre-assembled with clip, ready for installation.
Press and slide to install. Easy!
1. Align heat sink with chip and mounting pins.
2. Insert pins into anchor holes.
3. Set clip
3-1. Press and lock anchor slides.
3-2. Press and lock anchor slides.
4. Reverse side
Removal procedure can be done in the reverse order of the installation procedure.
If a phase change material is used with the heat sink, remove all of the phase change material, and make sure there is no residue left on the heat sink or chip surfaces. Apply a new piece of thermal interface material after cleaning.
