Abstract
Large-area electronics is becoming an embedded part of structural elements such as automotive and architectural glasses. In this paper, the effect of glass-lamination-based fabrication process on the electrical performance and production throughput yield (TPY) of printed conductive wires and surface-mounted (SMD) connectors on polyethylene terephthalate (PET) carrier film was investigated by measuring their electrical conductivity after lamination. Based on the experiments, lamination decreases the production yield of conductive wires and connectors due to broken wires or dislocated connectors, especially if they are located close to the corners of the laminate. On the other hand, lamination was observed to improve the electrical conductivity of wires. In addition, some potential failure mechanisms are discussed.
