Clamping Force & Thermal Performance Performance Data
■nVent SCHROFF Card-Lok retainers offer the highest clamping force available for cold wall applications. In a typical application two Card-Loks will be mounted either directly to the PCB or to a heat frame assembly via screws or rivets, and are then inserted into a machined cold wall channel within a rugged enclosure. When expanded, the Card-Lok will clamp the PCB in place. The amount of clamping force needed will depend on the application, specifically the amount of shock and vibration the board will be exposed to; too little clamping force may result in insufficient board retention and poor thermal performance and too great clamping force may result in damage to the Card-Lok, cold wall or printed circuit board.
●Thermal Performance PURPOSE OF TEST
■When two surfaces in contact have heat flowing across their junction, a measurable temperature difference arises caused by contact resistance.The purpose of this testing is to provide Design Engineers with a relative thermal resistance; actual performance will depend on the customer’s application and environmental conditions. If the product is to be used in a critical application testing should be done to ensure desired results.
