Applications of Plasma in the Manufacture of Electronic Devices

The electronics industry employs plasma for a range of applications to treat the surface of materials. These range from adhesion promotion of encapsulants and adhesives, to enhancing the release properties of optical disc master stampers.

Precision Cleaning with Plasma

One of the main applications of plasma is for precision cleaning of surfaces prior to operations such as metallization and solid state bonding. Examples include:

  • The automotive industry, where plasma cleaning is performed prior to spot welding
  • In the Electronics industry where it is used for printed circuit board fabrication where it is used to clean drill smear prior to metallization

Electronic Devices Requiring Water Tight Construction

Furthermore, in the electronics industry, plasma is used with connectors and feedthroughs to promote wetting of materials such as adhesives, encapsulants and sealants. This is of importance in applications such as water meters and submersible connectors and implantable cardiac defibrillators and pacemakers which require water tight construction
