| Abstract: | The new design and technology for surface mountable piezo-ceramic components, especially the filter for TV sets, are discussed. Based on the theory of piezo-ceramic thickness trapped shear, the novel structure and process technology are applied in the production of the SMD filters. The filters reach the level of the same kind in the world. They have been put into mass production; therefore has satisfied TV set manufacturers抎emends. The important processes in the production are wafer slotting, conductive paste dipping, flexible glue applying and resin sealing. |
