Introduction - "OBSOLETE" QuickSet (QS series)

Note : This page is for the obsolete QuickSet series, QS. In Jan-2018, the QuickSet series was revised from the QS to the QT. However, we will continue to supply the QS series and offer product support. Details

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.

PCB Board Holes

A minimum of 2 through holes are required in the board. The hole diameter must be 1.8mm(.071").

Features and advantages

quick set1 quick set5 quick set3 quick set4 Kept horizontal position
Small PCB Area

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.

Stable & Robust

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.

Location Guide

Heat sink location and orientation is precisely set by anchor and pin. The possibility of damaging the chip, heat sink, or thermal interface material d uring installation is greatly reduced as well as the possibility of installing t he heat sink in the wrong orientation or location.

Minimize bare-die damage during heat sink instration

Exposed dies can be damaged if the heat sink attachment load is applied to the edges or corners of the die. This can happen if the heat is tilted during installation. If the anchor pins are located inside of the heat sink footprint, they will act as guides when the heat sink is installed. The tight clearance between the anchor pins and the clearance holes will greatly reduce the ability of the heat sink to tip or tilt during installation, preventing contact with the edges or corners of the die.


Heat sink comes pre-assembled with clip, ready for installation.
It come easy to supervise parts and station.


Press and slide to install. Easy!

Removal Procedure

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.

Load Adjustment

The attachment load can be changed by adjusting the load adjustment pin height.

How to determine the attachment force/load:

quick set6
  1. Determine Y value : Y = PCB thickness + Chip height
  2. Make sure that Y value is within the working range.
  3. Choose K value from graph.

If the attachment force needs to be modified, requiring a different pin height,
please contact Alpha sales.
