Nordson MARCH has recently released a white paper showing the results of RF plasma processing on conformal coating adhesion, the conformity of the coating coverage, and the resulting effects on electrical functionality of a fully assembled printed circuit board. The research was done in conjunction with Nordson ASYMTEK, AirBorn Electronics, and SMART Microsystems (formerly known as Desich SMART Center). The paper can be downloaded at http://bit.ly/MARCH-PlasmaWP.

The corrosion of Nickel-Palladium-Gold (Ni-Pd-Au) finish terminals in humid environments is known to be reduced with the application of a conformal coating such as acrylic. Corrosion has a higher rate of occurrence around the terminal 'knee' of a surface mount component, which may be reduced with the application of conformal coatings. Although radio frequency (RF) plasma processing is generally known to enhance conformity of conformal coating to surfaces through ionic bombardment, the effect on the functionality of assembled printed circuit boards (PCB) is not as well known. The purpose of this study is to assess whether RF plasma processing can enhance the adhesive and coverage qualities of an acrylic conformal coating on PCBs

The purpose of this study is to assess whether RF plasma processing can enhance the adhesive and coverage qualities of an acrylic conformal coating on PCBs, specifically on Ni-Pd-Au terminals with a knee, and if plasma processing has an effect on the electrical functionality of components and fully assembled PCB.
