Displays for digital gauges and indicators, radios, on-board computers, mobile telephones, and laptop monitors are bonded with a flexible film or conductive rubber, using a hot sealing process. The film forms a flexible connection between the circuit board and the contact surface that generally comprises two thin panes of glass.
The simple principle used in Openair® plasma pre-treatment removes every trace of carbohydrates and impurities from these contact surfaces. This results in a uniformly high bonding quality and a reduction of scrap rates. The same applies to this process with hot bar soldering and micro-welding.
