With technology growing at an exponential rate, the demand for smaller and effective packages are increasing. Engineers
constantly face challenges of increasing functionality and components on a smaller board design. Mounting holes and anchor
pads take up valuable space necessary for maximum efficiency. EnzoTech's Uni-Holder® clip is designed with
this in mind. Introducing a new, revolutionary way of a BGA heat sink attachment method, the Uni-Holder® clip
is truly one step ahead of the competition. The Uni-Holder® clips simple plastic design is integrated with
springs through all four corners. By being spring loaded, this allows the clip to accommodate different heat sink height sizes
as well as helping to delicately balance the heat sink through vibration that occurs during transportation of the material.
The constant change in temperature within the casing can cause other forms of attachment methods to fail. The Uni-Holder®
Clip will not deform in the IC operating temperature and will provide a reliable way of heat sink attachment. Providing better
contact to the die on the PCB, this will help increase thermal performance beyond expectation.
for PC Board/IC design
When designing PC boards, there are areas that need to be reserved for the heat sinks' such
as drilling holes or anchor soldering. With EnzoTech's Uni-Holder® Clip, designers will not need to reserve
any drilling holes or anchor soldering when designing the circuit.
EnzoTech's Uni-Holder® Clip is
uniquely designed to maximize productivity and efficiency by using only the BGA chip space that is standard on the PCB.
Mounting holes on the PCB takes valuable space and reduces how efficient the PCB can be.
The Uni-Holder® clip can prevent the heat sink from loosening that are either caused by
fan vibration or any change in the physical adhesive material cause by heat or age. The Uni-Holder® clip
passed extensive shock and vibration tests: NEBS GR-63-CORE and ETSI EN 300 019-2-3 requirements. The pull force data featured
the Uni-Holder® clip to pass 20 lbs of force.
Time and Cost Saving
There are no tools required and installation can be done in a matter of seconds. Assembly time and money can be reduced with
the simplicity of the Uni-Holder® clip. The smart design allows for easy access to re-work the heat sink, and
is guaranteed to be reusable for at least twenty times before the lip shows any signs of wear.
does Uni-Holder® clip work?
In between the PCB and substrate, solder balls are present and provides a minimal gap that is between 0.5mm and
0.7mm. Simply slide one side of the clip into the gap, and gently press on the other side until the clip is "snapped on". The
clips lip thickness is between 0.18mm and 0.35mm, which provide plenty of extra space. The clip simply grabs onto the
substrate with the small lips that are on the edge of the clip, without doing any damage. Snap on, and you're ready to go.
Variable footprint Sizes from 15mm to 45mm
The Uni-Holder® Clip is
available in most BGA foot print sizes that are in the market. Enzotech offers a variety of heat sinks that are applicable
with the Uni-Holder® clip. From forged pin fins to forged elliptical fins, you can choose the heat sink that
is best suitable for your application. If there is a special need that is in demand, the Uni-Holder® clip is
customizable to your specific needs.
