Fifteen times higher temperature cycling capability

100% solder-free IGBT module with proven durability


Nuremberg, 24 November 2009 - SKiM, the three-phase IGBT module for DC/AC and AC/DC inverters in electric and hybrid vehicles and industrial applications, has a temperature cycling capability fifteen times higher than standard soldered modules. These modules have also been tested at levels well beyond standard industrial test conditions and the results of these tests have shown that they are very resistant to ambient temperature changes, cooling changes and operational effects.

 

SKiM modules are characterised by proven mechanical stability at levels above standard industrial test conditions, reaching 10g compared to the industrial standard of 5g in the vibration test and 100g compared to the industrial standard of 50g in the shock test. The total module resistance is 0.3 mOhm compared to a typical industrial level of 1.1 mOhm. SKiM withstands stringent requirements for endurance during high acceleration and vibration stress.

 

Sinter interconnects and solder-free pressure contact technology ensure a 100% solder-free module, eliminating the solder failures that can occur at high temperatures.

 

SKiM modules are assembled quickly and easily onto the heat sink using only screws, with no solder steps. The modules are supplied with pre-applied thermal paste to ensure homogenous and optimised thickness of the paste. Power boards are also assembled without any solder steps, using spring contact technology. The combination of these packaging and connection technologies results in a cost-efficient and time-saving inverter assembly process.

 

SKiM 63 and SKiM 93 modules are available with blocking voltages of 600V, 1200V and 1700V, and nominal currents from 300A to 900A. Two case sizes are available: SKiM 63 measuring 120 x 160mm² and SKiM 93 measuring 150 x 160mm².
