Abstract:
1. A method for forming electrically conductive patterns to provide an electrically conductive path on polymer tubing comprising the steps of: (a) establishing a polymer tube having an axis defining an axial direction; (b) mounting said polymer tube in a displaceable and rotatable mounting adapted to provide both axial and rotational motion; (c) forming at least one channel having a predetermined pattern in said polymer tube with a focused energy beam; (d) filling said at least one channel having a predetermined pattern with an electrically conductive paste or electrically conductive slurry material, said electrically conductive paste or electrically conductive slurry material being formed of conductive particles and precursor compounds which convert to solid-phase electrically conductive compositions at temperatures of less than 250° C.; (e) heating said polymer tubing to temperatures less than 250° C. to cure said electrically conductive paste or electrically conductive slurry material; and, (f) covering said electrically conductive paste or electrically slurry material with a polymer layer.
