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.
