A positive mechanical detent is built into the
cam rod shown here in cross section.
Improving the thermal conductivity of
circuit board retainers enhances system
performance by increasing the reliability
of electronic components and circuit
modules.
Extensive testing of ZIF retainers in
the CTS Engineering Test Laboratory
demonstrates that they have the best
thermal performance of any circuit board
retainer available.

The ZIF cam detent design gives
added assurance that a PCB will remain
securely locked in position even under
extreme vibration and shock levels.
Detent action occurs during the final 15
degrees of cam rotation and virtually
eliminates any possibility of the cam
unlocking under environmental stress.

Clamping pressure is not only
essential to heat transfer, but also a
critical requirement for retention of
PCBs under severe shock and vibration.
ZIF retainers have been subjected to the
most extreme test conditions specified in
MIL-STD-810C.
Nominal retention force for a circuit
board held captive by a pair of ZIF
retainers (I/O connector excluded) is
shown in the graph at the left.
Technical Assistance for Custom
Designs - Our engineering staff has
extensive experience in the packaging of
ZIF retainers. Modification of standard
housings, cams and spring configurations
for special design applications is frequently
possible. Contact the CTS factory in
Burbank, California. We welcome the
opportunity of providing you with the
assistance needed to solve all of your
thermal management problems.
