CTS®
iZIF ^™ HEAT FRAME
GENERAL DESCRIPTION
The iZIF^™ is a custom aluminum heat frame that integrates
the PCB retainer for improved structural integrity and thermal
efficiency (.8°C-in./W). The iZIF^™ is a highly reliable patent-
pending design for rugged military and aerospace circuit card
applications. It features a quarter-turn lock, uniform clamping
pressure, and can be sized to fit small daughter cards up to
9U VME. A bottom plate may also be added for additional
cooling and structural integrity. The iZIF^™ features a 1/8”
stainless steel socket head cap rod with beryllium copper
spring. A variety of finishes are available such as chemical
film, black anodize, and electroless nickel.
THERMAL LINKS
GENERAL DESCRIPTION
CTS’s thermal links provide superior retention because
of the 6 to 8-segment fingers versus the 2 or 3-segment
fingers available from other manufacturers. These thermal
links are offered for TO-5s, TO-8s and TO-18s with or
without BeO washer and other appropriate hardware.
They provide an effective retainer and efficient thermal
path between semiconductor and heat sinks or chassis.
There is excellent transistor retention under high
vibration and shock loads. The thermal links can be
inserted and removed multiple times without loss of
retention or damage to the finish over the entire JEDEC
case diameter range. They can be installed with a rivet or
eyelet, soldered to a PC pad or heat sink, mounted with a
single screw or with a threaded stud and hex nut.
