|INDUSTRIAL PLASMA APPLICATIONS
Gas Plasma is used widely throughout the world
for a broad variety of industrial applications covering
industries such as automotive, aerospace,
batteries, electrical, food packaging, electronics,
fuel cells, glass, optics, plastics, packaging, shipbuilding,
space, and textiles. New applications are
being developed daily and the field continues to
grow at an enormous rate because it offers an environmentally
friendly and cost effective alternative
to wet chemistries.
Plasma activation of electronic connectors and
sensors prior to potting and encapsulation ensures
an excellent hermetic seal, reduces current leakage
and provides stronger physical bonding to the
Plasma activation raises surface energies and ensures
good wettability, and more complete flow of
resins onto almost all low energy polymer materials,
including PTFE, silicone rubber and Kapton®.
Polymer surfaces are made bondable by the reactive
chemistry present in the plasma. New chemical
functional groups are formed with strong chemical
bonds to the bulk of the plastic allowing both aqueous
based solutions and adhesives to wet into every
crevice of the material. This allows a tremendous
improvement in bonding, sometimes up to 50
times the strength of the traditional bond.
Residual cleaning of organics at the molecular level
on materials such as glass, metals, plastics,
polymers or composites prior to bonding, potting,
printing, marking, painting or labeling.
Plasma de-smear and etch-back of PCB’s allows
for the smear left on via walls after drilling to be
removed before metallization can occur.
In the optical disc mastering industry plasma
cleans optical disc stampers, improves replicate
release properties, and is used to eliminate certain
types of defects on the disk masters.
