Elimination of Surface Defects For Printable High Density Gold Conductor Pastes

摘要

Surface defects for screen-printed gold conductors were investigated in order to identify their root causes. Several mechanisms were proposed to explain different types of surface defects, such as domes or blisters. Using these mechanisms, modifications to the paste formulation and the manufacturing process were established to prevent these defects. The new methodology provided several gold conductor pastes with defect free surfaces and lower cost to use.
