Abstract

PURPOSE:To reduce the effect of thermal distortion given to quartzs through the reduction in frequency adjusting time, by suppressing the dispersion of specific number of oscillations as less as possible for blanking of a tuning fork type quertz oscillation bar fomed with a chemical etching process. CONSTITUTION:Several hundreds of tuning fork type quartz bars 1 are regularly coupled in a quartz wafer 2 at the external frame via a bridge 4. Electrodes 5 formed on the surface of the wafer 2 are extended to the frame 3 to be a common electrode 5a, and electrodes 6 formed at the back is also taken as a common electrode 6a. The quartz bars 1 measured for the specific frequency are then picked up by several pieces from the wafer 2. A resist 9 is coated on an electrode film 8 of the electrodes 5, 6 attached at the full circumference of tip of the chips 1 of the wafer 2. The resist 9 is then exposed and developed to expose the electrode film 8, and a current is applied from the electrodes 5a, 6a for plating to form the frequency adjusting plating sections 5b, 6b. This plating thickness is adjusted basing on the measuring value of the chips 1.
