STANDARD ZIF CIRCUIT BOARD RETAINERS
CTS®
THREE ZIF CONFIGURATIONS
■ STANDARD ZIF (coldwall mounted)
■ ZIF III (PCB mounted)
■ MACHINED ZIF (ZIF geometry
machined into coldwall)
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.
Engineers who specify the ZIF retainer can have
confidence that it will perform as described. Complete
product specifications are available upon request.
The following CTS laboratory test procedures, reports
and results are available upon request:
• thermal performance testing
• shock testing
• vibration testing
• torque testing
• life cycling
DESIGN FEATURES
■ _{QUICK LOCKING ACTION}
The locking operation which secures the PCB in the ZIF retainer requires only a 1/4 turn of the
rod assembly.
■ UNIFORM HEAT TRANSFER
Uniform clamping pressure eliminates hot spots along the PCB interface producing an even
distribution of heat along the entire edge.
■ COMPLETE INTERCHANGEABILITY
ZIF component parts are designed to assure consistent performance and interchangeability of
all identical part numbers.
■ _{OPERATING ENVIRONMENT}
ZIF characteristics are unaffected by adverse environments typically encountered in military
and industrial applications.
■ VISUAL INDICATION
ZIF provides a visual indication that the rods are in the “open” or “closed” position relative to
the position of the drive assembly.
■ _{MAINTAINABILITY}
The unique design and interchangeability of like parts make field repairs quick and simple. Repairs
can be accomplished without the use of any special tools. Although ZIF retainers have been tested
for over a thousand lock-unlock cycles, they have been derated and specified for 400 fully loaded
cycles. This, in most cases, will exceed the overall system life, virtually eliminating service or
maintenance to ZIF assemblies.
