Laser Cutting Residue
Substrate: Flexible Electronic Substrates
A Laser-based cutting process produces a conductive carbonaceous soot on the polymeric surfaces along the Laser cut pattern which must be removed prior to next steps in the device fabrication process. The soot is a potential cause of electrical shorts and interferes with subsequent electroplating operations.
