Cookson electronics is a leading materials science company that provides high performance materials, chemistry and technology solutions to the electronics and surface finishing industries worldwide. The alpha pv-ready-exactalloy family of resilient flux coated preforms for photo voltaic [pv] applications provide a unique solution to the challenges of providing an exact volume of solder and flux for critical backside only soldering applications in the solar panel assembly process. Specifically formulated for backside interconnects, resilient flux and additional solder volume is selectively applied to solder coated copper preforms to eliminate the need to dispense solder paste or flux. The result is a more controlled volume of solder and more consistent soldering results. Alpha pv-ready exactalloytm preforms are machine ready for automated assembly. Alpha pv-ready exactalloytm preforms are provided in customer specific shapes to meet the unique interconnect requirements. Resilient flux is a non-tacky flux coating that can be selectively applied along with solder to target specific soldering points. Solder and flux type can be optimized to meet specific interconnect requirements. Reaction and decomposition vapors associated with voc emissions during soldering are greatly reduced.
