Abstract

For high-volume products low-cost techniques for multilayer polymer-based thick film wiring board manufacturing are needed. Screen-printing is a cost-efficient technology candidate to build up approximately 6 conductor layers on both sides of a flexible substrate. In order to experimentally evaluate the feasibility of screen-printing technique, the printing resolution was tested on different substrate materials, such as, polycarbonate (PC), polyethylene terephtalate (PET), polyimide (PI) and liquid crystal polymer (LCP). Conventional screen printed polymer thick film pastes were characterized on polymer substrates to form multilayer fine-line patterning and through-hole vias. The final demonstrator was a double-sided PI substrate having two conductor layers separated by dielectric layers on both sides of the substrate and through substrate vias.
