Industry & Occupation
Classification
Summary
A job responsible for the manufacturing process of quartz crystal units that require ultra-high precision. Handles cutting, polishing, adjustment, assembly, and inspection.
Description
Crystal Manufacturing Worker (Quartz Oscillator Manufacturing) processes quartz raw stones to manufacture quartz crystal units, which are oscillation elements. Machines them into wafer shapes using grinding and polishing machines, finishes the surfaces with chemical etching, forms electrodes, packages them using special soldering or bonding techniques, and then performs frequency measurement and evaluation in a clean room. Since minute processing errors directly affect product characteristics, high attention to detail and precision measurement skills are required.
Future Outlook
With the high performance of electronic devices and the expansion of IoT demand, the demand for high-precision frequency control elements remains stable, and manufacturing automation and advanced microfabrication technologies are expected to progress.
