The ability to solder at low, controlled temperatures (connection temperatures must be maintained below 300°C) within a short time window, also reduces the stresses on the cells and the likelihood of micro-cracking, while still producing a controlled, high quality solder joint. OK International introduces the perfect solution: The PS-900-Solar Soldering System offering low cost of ownership, ease of use and unique Smart Heat® Technology. Smart Heat® supplies power on demand using a calibration-free system that reacts instantly to changing thermal demands, thus minimizing thermally induced stresses on the surface of the solar cells. The PS-900-Solar combined with the specially designed STV-DRH440A hoof tip optimizes the power delivered to the solder joint providing high performance efficien
