Methods for forming electrically conductive heated dielectric panels are
provided. The panels are utilized for warming objects and/or insuring
unobstructed viewing through the panels by removing moisture. The methods
include depositing electrically conductive metal bus bars onto the
dielectric panel, onto which panel a conductive coating has previously
been disposed. The conductive metal bus bars are deposited onto the
coated dielectric panel through the use of a circularly rotating or an
inline heating head and mask apparatus, in combination with an
oxyacetylene or a plasma device. A metallic tab, which extends from the
panel peripheral edge, is brought into electrical contact with each
conductive metal bus bar for external electrical connectivity.
