Purpose: Within many existing plasma technologies, air plasma at atmospheric-pressure remains one of the most commonly used in multiple industries. The implementation of air plasma at atmospheric-pressure is trendsetting in the conformal coating marketplace while low pressure plasma technologies are widely used for cleaning applications. This paper will review various plasma and gas systems and will explain how a newly developed cutting-edge blown air plasma at atmospheric-pressure process leads to the treated surface's functionalization, transferring chemical energy for drastically increasing the conformal coating reliability while preserving boards' integrity. This paper will also review the suitability of blown air plasma at atmospheric-pressure to specific modern challenges of the conformal coating including de wetting defects and adhesion issues solving. Detailed examination of the effects of this blown air plasma at atmospheric-pressure process on substrates will be presented based on numerous experiments, results and laboratory findings. This paper will cover specific design configurations that allowed us to design and release an equipment to ensure the benefits of this patented plasma process, enabling flexibility, in line integration, automated programming, selectivity and reliability, known as the major expectations of the electronic industry.
