A METHOD OF FORMING A PATTERN OF ELECTRICAL CONDUCTORS ON AN INSULATING BASE MATERIAL COMPRISING PREPARING A PASTE WHICH INCLUDES COPPER POWDER CONTAINING REDUCIBLE CONTAMINATION PRODUCTS, SORBITOL IN AN AMOUNT EQUAL TO ABOUT 1-20% BY WEIGHT OF SAID COPPER, AND A VOLATILIZABLE DRYING AGENT, PROVIDING SAID INSULATING BASE WITH A HEAT-HARDENABLE ADHESIVE SURFACE, APPLYING SAID PASTE TO SAID ADHESIVE SURFACE IN THE FORM OF SAID PATTERN, AND HEATING TO A MODERATE TEMPERATURE SUFFICIENT TO REDUCE SAID REDUCIBLE CONTAMINATION PRODUCTS AND TO DRIVE OFF SUBSTANTIALLY ALL EASILY VOLATILIZABLE SUBSTANCES PRESENT.
