Screen printing paste

The screen-printing paste is made up in the manner described in Section 4.2.2 and the patterns printed. The heater element and its leads would typically be platinum and the interdigitated electrodes gold. As illustrated below (Fig. 4.49) the heater might also be a composition based on ruthenium oxide (see Section 4.2.2). The contacting tabs are also screen-printed gold.

The following discussion is directed to the preparation of photoformed 2-to 3-mil metal conductor circuits. The previous analysis, regarding the use of screen-printed dielectrics to prepare circuits, was presented in detail and also applies to the preparation of conductive circuitry. The need for increased circuit density clearly applies to gold, copper, silver, and other conductors. The screen-printed pastes contain conductive metals and glass frits vs. the dielectric paste, which generally contains a dielectric and a glass frit.

As a conclusion, the viscosity problem can be solved using the different wt% of thinner (2,4,6, 8,10 and 12 wt %). The phenomena observed from screen-printing pastes are also identical to those reported from literature that the viscosity of the p>aste throughout the screen-printing...
