发明名称 METHOD OF MAKING A PIEZOELECTRIC TRANSDUCER
摘要 For connecting external leads to miniature solid-state devices of the type wherein an electric circuit element is photoetched, printed or otherwise bonded upon a substrate surface, lands are embedded in the substrate and exposed to the circuit supporting surface of the substrate. The lands provide a surface large enough to enable the circuit elements and external leads to be individually connected to separated regions of the exposed portion or portions of the lands.
