Eco Block Solder Bond Modules Infineon Eco Block Solder Bond Modules are ideal for applications where the high robustness of pressure contact technology is not necessarily a must. Typical applications are drives, power supplies, and soft starters. Designers benefit from improved terminal design for symmetric current sharing and the 100% x-ray monitoring of solder process which leads to predictably high performance and lifetime. With the second generation for 34mm, you can get increased current ratings (up to 240A).
