Decision	composite busbar ribbon	pure copper busbar ribbon	Acceptance basis
Current collection	Layered section collects current through the busbar path	Copper section collects current through the busbar path	Fix string layout, length, allowable resistance and thermal rise.
Forming	Check layer integrity at bends and exposed cut edges	Check copper temper and bend geometry	Use the actual busbar width, thickness, radius and assembly restraint.
Joints	Qualify solder or weld access to the specified surface layer	Qualify solder or weld on the copper grade and coating	Measure joint resistance and mechanical acceptance after the specified thermal cycles.
Cost basis	Include changed section, joining and coating operations	Include copper section and joining operations	Use cost per accepted current-collection assembly.
