- Application Guidelines
Always mix ink thoroughly before using and during, as silver will settle quickly. Continuous agitation during application is recommended. If silver settles to a hard pack in container, then aggressive mixing is required to break up the silver chunks and redisperse them in the liquid.
Thinning & Cleanup
Use MEK or other suitable solvents. If faster drying time is required, contact Applied Ink Solutions for solvent recommendations. Do not allow ink to set on an inactive press for any length of time. Always check the viscosity of ink that has been recovered from a press and add small amounts of solvent while mixing thoroughly to restore viscosity. Solvent can be added to reclaim thickened ink as long as the ink has not dried and hardened completely.
Drying
It is essential that all residual solvent be removed from this ink once it is applied. Incomplete drying will cause the ink to appear dry on the surface while trapping solvent underneath the surface. Over time, this trapped solvent will migrate out of the ink, and can cause adhesion problems with any material, such as dielectrics, applied over the ink.
Completeness of Drying
Evaluate the point-to-point resistance along one of the screened conductive paths after one pass through the drying oven or one cycle in a batch-drying oven. Run the substrate through another drying cycle. Measure the point-to-point resistance again along the same path and compare it to the original reading. If the resistance decreases by less than 10%, then the ink is essentially dry after the first drying cycle or pass through the oven. If the resistance decreases by more than 10%, then more drying time is required to completely remove the solvent.
