Application of Plasma Bridge for Grounding of Conductive Substrates Treated by Transferred Pulsed Atmospheric Arc

An atmospheric pressure plasma jet (APPJ) sustained by a pulsed arc (PAA) transferred on an electrically conducting surface was operated with mean power of 700 W, pulse frequency 60 kHz, and gas mixture N2 H2 up to 10% H2, flowing at 30 70 SLM. It shown that the bridge ignited between grounded injector floating substrates can be used for electrical grounding. This allowed transfer such substrates. The stable Argon flow through from 3 10 Its length 5 15 mm. current 350 mA. copper contact pads alumina electronic board were treated using Ar injection First, oxide film about 65 nm grown compressed dry air (CDA) jet. Then, this reduced speed 4 cm2/s forming 95/5 (95% 5% H2)
