QUARTZ OSCILLATOR MANUFACTURING METHOD AND QUARTZ OSCILLATOR |
摘要 |
<p>A method for manufacturing a quartz oscillator having a stable temperature drift characteristic attributed to the quartz oscillating piece and a quartz oscillator are disclosed. The method comprises a quartz crystal etching step (S1) of processing a quartz oscillating piece into a predetermined shape by etching, an electrode membrane forming step (S2) of forming an electrode on the quartz oscillating piece, a quartz crystal mounting step (S3) of mounting the quartz oscillating piece in an oscillator package, a leakage oscillation adjusting step (S4) of driving the mounted quartz oscillating piece, detecting the leakage oscillation, and removing a part of the quartz oscillating piece depending on the detected leakage oscillation, and a re-etching step (S6) of re-etching the quartz oscillating piece subjected to the removal.</p> |
