HIGH TEMP FAN HEAT SINKS - FHS-090 SERIES

High Operating Temperature Integrated Fan Heat Sinks

DESIGN FEATURES

■

Industry-leading maximum operating temperature of 90°C

■

Compatible with chipset footprints ranging from 21x21 mm to 45x45
mm

■

Total heights from 16.1 mm for low profile applications to 44.6 mm
for lowest thermal resistance

■

Common 5VDC @ 0.5 A (max) USB 2.0 fan electrical specifications

■

Forged and extruded versions available

■

Choice of elliptical, round pin, and plate fin styles

DESCRIPTION

The FHS-090 Series of integrated-fan heat sinks is uniquely designed to absorb and disperse heat away from
high temperature devices while offering key features such as an operating temperature range of -10°C

to 90°C,

calculated MTTF @ 90°C: 86,858 hours (GEM, 90% confidence) and various package sizes to best fit the
application. Thermal resistance values range from 4.07°C/W to as low as 1.24°C/W.

These new fansinks can maintain superior thermal dissipation for devices that emit high amount of heat. CTS’
fansinks are available in a wide range of footprints and fin heights which make them suitable for many elevated
temperature applications such as component testing, burn-in, high density servers, high- speed computing and
video, and use in areas where the system airflow is constrained.

GENERAL DESCRIPTION

The ZIF retainer is a totally self-contained, precision

assembly that provides a highly effective thermal interface
between the circuit board and coldwall. Board lengths
between 1-1/2” and 12” can be accommodated.

A ZIF retainer consists of:

(1) an aluminum housing

(2) a rod/cam assembly constructed from an aluminum

or stainless steel double flat rod extrusion. The ZIF
rod assembly is driven by one of three options: pin,
hex-head or screwdriver slot

(3) a beryllium copper spring

ZIF retainers are mounted to any flat metal surface (coldwall).

The standard configuration is attached with 4-40 hardware.
However, the retainer housing can be supplied with tapped
holes for M3x.5 metric hardware, or left undrilled with only
index pins for vacuum brazing, dip brazing or epoxy bonding.

TECHNICAL ASSISTANCE-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. We welcome the

opportunity of providing you with the assistance needed to

solve all of your thermal management problems.

SPECIFICATIONS

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.

Improving the thermal conduc-
tivity 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.

3°C-inch

WATT

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.

THERMALLY EFFICIENT, 0.9°C-INCH/WATT

GENERAL DESCRIPTION

The ZIF Prime is the latest in state-of-the-art rugged retainers

released by CTS Electronic Components. It offers the most
common finish and actuation styles and maintains the superior
thermal and mechanical features of the ZIF III. New additional
features include lower locking/unlocking torque requirements
and enhanced visual indication of locked/unlocked status.

The ZIF Prime is a totally self-contained precision assembly

that provides a highly effective thermal and mechanical interface
between the circuit board and coldwall. The ZIF Prime retainer
is mounted to a heat frame or directly to the PC board and
provides exceptional thermal performance while allowing the
rapid exchange of electronic circuitry to minimize equipment
downtime.

Primary characteristics of the ZIF family of retainers

include quick and easy installation with a 1/4 turn lock and
unlock, uniform contact area to enable uniform board pressure
and heat transfer, superior thermal performance and capability

to withstand rugged environments.

PRODUCT BENEFITS

■

Standard parts consist of:

•

Aluminum housing with black anodize
finish

•

Stainless steel rod with 3/16 in. external hex head,
passivated

•

Beryllium copper spring, electroless nickel-plated

•

2-56 screw mounting

■

Thermal impedance of 0.9° C-in/W (equivalent to

ZIF III)

■

Direct drop-in for ZIF III parts in terms of performance

and mounting pattern

■

Same 1/4 turn locking procedure as Standard ZIF and

ZIF III products

■

Enhanced visual indication method for determining

locked/unlocked part status

■

Recommended slot width of .300 in. (7.62mm) + PC

board thickness; tolerance ±0.005 in. (0.13mm)

■

Capable of operating in rugged environments as per

MIL-STD-810

This table indicates the mechanical and thermal

characteristics of the ZIF Prime based on different
retainer lengths. The values shown are for a pair at nominal
dimensions and can be used as a baseline for design
purposes. ZIF Prime retainers should be tested in final
customer configurations as mechanical interfaces can
impact retainer performance.

THERMAL LINKS

GENERAL DESCRIPTION

CTS’ thermal links provide an effective retainer

and efficient thermal path between semiconductor and
heat sinks or chassis. CTS’ unique design gives

superior retention and thermal conductivity due to
their 6 to 8-segment fingers versus the 2 or 3-segment
fingers available from other manufacturers.
