Process and Quality Improvement of Pastes and Inks Using MAZERUSTAR®

摘要

Conventional methods of paste and ink preparation are compared against a modern mixer design. Mixing/kneading and deaeration are performed simultaneously in very short application times without using a mixing rod or blade system and without an evacuation condition. Three different paste systems were evaluated comparing conventional mixing methodology versus mixing with a MAZERUSTAR®, namely a silver paste, a AgPd electrode paste, and a glass (white) ink. MAZERUSTAR® processing of each system showed marked improvement of the paste prior to subsequent processing and also showed reduced process repetitions necessary to achieve specification conditions, such as FOG, viscosity, and paste stability. Higher process yields were obtained with MAZERUSTAR® processing as well as lower waste generation.
