Tabs
Aavid’s Shur-Lock self locking stand-off tab (U.S. Patent
#5,437,561) positively secures any heat sink to the printed circuit
board. This Shur-Lock tab exhibits many unique design features.
The rounded and bifurcated tip of the Shur-Lock solderable tab
has been designed to easily snap into any 0.093” diameter hole.
Once through the hole, the tab provides a positive resistance to
backing or falling out of the hole. In addition, the spring action
between the tab and the plated through hole prevents leaning
or lift-off of the heat sink prior to or during the soldering process.
The tip extension of the Shur-Lock tab has been designed to
protrude less than 0.060” beyond the back of a standard 0.0625”
PC board, which is below the normal lead trimming allowance
for assembled PCBs.
Shur-Lock’s stand-off design facilitates the cleaning of assem-
bled PCBs and permits electrical traces to be routed under the
heat sink. The wide base supports of the tab further improve
the stability of the heat sink assembly.
Positive PCB engagement
Integrated PCB stand-off
Quick “snap-in” assembly design
Reduces installed assembly cost
Designed for rugged shock
and vibration environments
Can be installed on a variety of stamped
and extruded board level heat sinks

Aavid solderable tabs stake onto heat sinks for solder mounting into the
PC board. The tabs are available in a variety of lengths, widths and thicknesses.
Tabs are factory applied for both vertical and horizontal mountings including:
step tabs, which keep the heat sink elevated above the board, and tabs with a
triangular base for extra stability.
Many of Aavid’s tabs are customized. Below are examples of standard tabs.
Please consult Aavid’s customer service department for information about
other tab options.
