Permanently secure printing for circuit boards using resistor paste, thanks to Openair® plasma

To get secure adhesion and good electrical characteristics from resistors printed on a circuit board, the surface tension of the component must be greater than that of the ink, or in this case of the resistor paste.

Plasma treatment for reliable printing on circuit boards

Openair® plasma has produced this surface activation for years now in the inline process for manufacturing safety-related sensors for the automobile industry. Plasma treatment ensures permanent ink adhesion at the highest standard.
