The need to reduce PV manufacturing costs combined with the present shortage of polysilicon feedstock is driving a
steady reduction in wafer and cell thicknesses. Hand soldering of tabs and stringers without causing damage or
latent defects to the cells is one of the steps that has become more challenging. Cells can break during the process
or crack in the completed modules. Process equipment such as soldering irons must adapt in order to maintain high
yields with acceptable mechanical and module reliability as the industry shifts the wafer thickness below 200
microns.
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 SmartHeat® Technology.
SmartHeat® 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
efficiency with increased tip life.
