Abstract
A process wherein a low viscosity, metal-containing paste is screened onto a ceramic greensheet and then sets up to increase its viscosity. In one method, the low viscosity is caused by excess solvent which is then blotted or otherwise removed so that the viscosity of the paste is increased. In an alternative method, the low viscosity paste contains a cross-linking agent which causes the paste to increase its viscosity after screening.
