The number of cells per string, the space between cells, the ribbon length, the stress bend location, and the soldering process parameters are all software programmable. High intensity lamps provide radiant thermal energy to solder the ribbons to both sides of the cell in a single step. The lamp assembly is mounted on a sturdy hinged bracket for easy service access. 1000 Specifications 1. The machine processes solar cells at a throughput of up to 700 cells per hour, resulting in substantial cost savings in high volume production through improved yield and reduced labor.
Solar cells are unloaded from stacks and edge-aligned with a mechanical aligner.
Tab material is fed from reels, coated with flux, cut to length, and provided with a stress-relief bend. Tabs and cells are aligned for soldering. High-intensity lamps in the solder head assembly provide radiant thermal energy to the cell and tabs. Both front and back cell contacts are soldered in a single heating step. A variety of solar cell sizes and shapes can be processed.
