Industry & Occupation
Classification
Summary
A skilled job that measures and inspects the oscillation frequency and electrical characteristics of crystal oscillators in the manufacturing process, confirming compliance with standards.
Description
The Frequency Measurement Inspector (Crystal Oscillator) is a job that checks whether manufactured crystal oscillators meet the specified oscillation frequency, capacitance, and other electrical characteristics. Uses measuring instruments such as oscilloscopes, spectrum analyzers, and high-precision frequency counters to measure samples, records and analyzes the measurement results as data. Based on the measurement results, sorts and reports defective products, contributing to quality maintenance. Since temperature and environmental factors affect measurement accuracy, also performs measurement condition control and device calibration tasks.
Future Outlook
With the expansion of demand for IoT devices and communication equipment, the demand for quality control of high-precision crystal oscillators remains stable, and proficiency in higher precision and miniaturization technologies will be required.
