Announcement of new QSZ clip attachment
Issue Date: 2011/01/11
qsz clip

Alpha is proud to announce the availability of a new and innovative heat sink attachment mechanism.

Electronic components have become faster and more compact, generating more heat and increasing thermal densities. This has led to the use of heat sinks of increased size and mass. One of the biggest challenges for thermal/mechanical engineers is mechanically mounting larger heat sinks while minimizing the amount board real estate used by the attachment mechanism. Generating sufficient attachment force is also critical with regards to mechanical security and proper performance of thermal interface materials.

Alpha's new QSZ clips have been designed to address both issues, providing secure and reliable attachment while requiring the absolute minimum of board real estate.

QSZ clip features and advantages:

quick set1 qsz1 qsz3 qsz2
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.

Multiple Clip & Anchor Pin Option

12 clips & 2 anchor pin lengths will be standardized, allowing many of our standard heatsinks to be used AS-IS with our QSZ clips and anchor pins.
This can eliminate the additional cost of a complex or customized heat sinks.

Flexible Design

Custom clip layout is quick and simple to produce.
Nearly any anchor location and catalog heat sink can be used.

Backing plate

Available for thin PCBs or applications requiring a high clip load.

Initial availability is scheduled for mid Feb-2011.
