INTA Technologies Corporation provides thick film metallization services that
utilize a Moly-Manganese (MoMn) refractory ink specifically designed for
oxide ceramic bodies to provide one of the industries strongest bond
strengths. Other formulations are also used by INTA, especially silver and silver-palladium. Inks can be applied by screen printing, roll printing, hand painting, air brush spraying, immersion and centrifugal coating. Inks are fired onto the ceramic at approximately 1300-1400 degrees C. in a hydrogen/nitrogen controlled atmosphere (INTA owns and operates several hydrogen atmosphere furnaces) in the case of MoMn. Silver inks are fired in one of INTA's air furnaces. The glass phases in the MoMn metallization bonds with the glass phases in the ceramic yielding peel strengths of 10-20 pounds. The metallized surface is now electrically conductive. Typically the surface is sulfamate or electroless nickel boron plated to help provide a more "wettable" surface during sequential brazing or soldering operations.
