Thermal Clamps Series SIHD GT Board to Board Interconnect Solutions www.amphenol-socapex.comThermal Clamps Thermal Clamps Amphenol Series SIHD GT Amphenol Series SIHD GT zzzzzzzzzzzzzzzzz MAXIMUM RELIABILITY QUICK LOCKING AND UNLOCKING : Unlike others on the market, Series SIHD- GT thermal clamps feature a quick, quarter-turn locking mechanism that provides a positive and fast assembly. Amphenol offers a new advanced MAXIMUM RESISTANCE TO SHOCK AND VIBRATION : Very low wear and design. Series SIHD-GT thermal resistant to extreme shock and vibration, even when used in harsh environments. clamps are designed to ensure the thermal coupling (heat dissipation) NO MOVING PARTS : The precision assembly permits the three components between the heat sink of a printed circuit board and the cold wall of a (body, spring and rod/cam) of the thermal clamp to stay together, even when in the box (for Daughter Board), or of a unlocked position. backplane (for the Mother Board). SENSITIVE AND VISUAL INDICATION : The top end of the rod/cam provides a visual indication that shows the open or closed position for ease of inspection. At the same time they ensure the guiding of the boards in its locations, as well as the locking of the Daughter Boards into the right position relative MAXIMUM THERMAL TRANSFER to the Mother Board by a 1/4 turn. UNIFORM HEAT TRANSFER : Its unique design produces a uniform pressure Ease of use, safety in vibration, low distribution along the PCB edge for absolute best heat transfer, which avoids weight and space saving are benefits damaging the heat sink and provides a better thermal conduction. of this design. The uniform clamping pressure eliminates hot spots along the PCB interface Series SIHD-GT thermal clamps are producing an even distribution of heat along the entire edge. available in the following designs : - a left type and a right type, Thermal couple between the cold wall and the heat sink is created by a direct - different platings, metal to metal contact providing more heat transfer capability than conventional - variety of lengths, wedge style retainers due to the constant pressure and the flexibility of the spring. - different locking devices (standard and custom tools). ZERO INSERTION AND EXTRACTION FORCES : The insertion and guiding process of the PCB in its location requires no additional force. Board lengths between 80 mm (3.15 in) and 240 mm (9.45 in) can be accommodated once the cold wall and heat sink are specified - in increment of 20 Avionic systems mm (0.787 in). Submarine equipment Ground military vehicles Series SIHD-GT thermal clamps are compatible with different heat sinks thicknesses. Superior retainer for high MAINTAINABILITY : the unique design makes field repairs quick and easy. density electronic devices Repairs can be accomplished without use of any special tool. Although the SIHD- running in very high vibration GT thermal clamps have been tested for over one thousand lock-unlock cycles, they have been derated and specified for 500 fully loaded cycles. This, in most environments. cases, will exceed the overall system life, virtually eliminating service and Designed to comply with MIL- maintenance. STD-810E. Various mounting options are available. Other custom styles are available upon request.
