Compare at module level
A copper-clad aluminum ribbon combines a copper surface with a lower-density core. Copper use and mass can change, but the complete ribbon structure must still meet the resistance and joining requirements of the module.
Start with the current process
Record the cell technology, ribbon dimensions, solder system, stringer settings and acceptance criteria. Compare candidate ribbons for solderability, peel strength, handling, cell stress and electrical performance. Use the module’s qualification requirements to define the reliability tests.
Calculate the full cost
Compare cost per finished module, including ribbon consumption, yield, power impact, process changes and qualification. A lower price per kilogram does not establish a lower module cost.
Share the cell platform, current ribbon, soldering conditions and resistance and peel-force targets.
