Optimal printing requires the surface tension (ST) of the ink to be matched with the surface energy (SE) of the substrate.
When the ink ST is higher than the substrate SE, (Figure A) contraction and pearling is the result of poor wetting. When the ST of the ink is lower than the SE of the substrate (Figure C) over-spreading occurs causing circuit lines to fuse.
Using proprietary plasma technology, NORCOP is able to fine tune and customize the surface energy of a substrate in order to align it to the surface tension of the ink (Figure B). As a result, pin-hole free, ink-jet-printed circuits exhibit a drop in resistivity and a consequent increase in conductivity.

Optimal printing requires the surface tension (ST) of the ink to be matched with the surface energy (SE) of the substrate.
When the ink ST is higher than the substrate SE, contraction and pearling is the result of very poor (21 dyn/cm) or poor (42 dyn/cm) wetting. When the ST of the ink is lower than the SE of the substrate (case of SE = 50 dyn/cm) over-spreading occurs uneven line borders.
When the ink ST is equal to the substrate SE the edges of the printed lines are straight (no ink flow, see SE = 47 dyn/cm).
Using proprietary plasma technology, NORCOP is able to fine tune and customize the surface energy of a substrate in order to align it to the surface tension of the ink. As a result, screen printed pin-hole free thin line circuits exhibiting very low resistivity and a increased conductivity can be produced.
