This paper describes the supporting structure of surface mount type crystal resonators suitable for operation at higher frequencies. This supporting structure applies gold bumps to bond a crystal chip to a ceramic package. The gold bump bonding is applied to AT-cut high frequency fundamental crystal resonators which have extremely thin vibrating parts. As a result, the effectiveness of gold bump bonding in heat-resistance, long-term stability, and conductive reliability are verified by the experimental characteristics of the above crystal resonators
