In this work, the metallization requirements and development for an alternative fine line printing method to screen printing, called pattern transfer printing (PTP™), are discussed. This technique has been proven in high volume environments and shows impressive capability of printing lines down to 20 µm consistently and reliably. With such a major reduction (nearly 50%) in contact area and paste volume, there are some critical aspects of the metallization paste that must be addressed. After these modifications have been made, an efficiency gain of 0.14%abs is demonstrated for the PTP™ process versus that of a state-of-the-art screen-printed paste on an industrial scale under otherwise identical conditions.
