Abstract
A method for using a handheld plasma tool for controlled application of low temperature atmospheric pressure plasma to material surfaces, e.g. to enhance bonding and or cleaning is disclosed. The handheld plasma tool can include a hand grip, on/off trigger, display, indicator lights, indexing pin, marking device, cable connections for gas supply and electrical power, and a plasma head for generating at least one reactive gas species at a low temperature. The handheld plasma tool can employ a rotatable clamp for treating backside surfaces. The handheld plasma tool can include motorized wheels to scan over a large area at a controlled speed. Other optional nozzles can also be employed for specialized applications.
