Topic: Heat seal for bonding LCD displays. Cleaning prior to hot bar soldering and micro-welding. Cleaning conductive rubber.
Plasma cleaning ensures strong bonding of LCD 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.

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.
