Abstract
A targeted-annealing system can automatically cure a conductive paste that may bind cascaded strips of a string together without damaging the strips. The targeted-annealing system can process strings of cascaded strips on a supporting surface, and can anneal conductive paste between overlapping strips by blowing heated air on the overlapping sections of the strips. An air nozzle shaped to target the overlapping sections may provide the heated air. The supporting surface may include a porous material that allows a vacuum to pull on the cascaded strips from below the surface during the annealing process.
