Treating crystal oscillators with pressurized liquid for half an hour before they enter the taping machine is mainly done to protect device performance and improve production yield. The process optimizes product quality through several effects.
1. Removing Surface Contaminants
During production, transportation, and storage, dust, oil, and other impurities can easily adhere to the surface of crystal oscillators. Under pressure, the liquid can penetrate gaps and fine surface structures, dissolving, loosening, and carrying away these contaminants. If impurities remain, they can interfere with signal transmission and reduce frequency stability. This treatment helps avoid such problems and improves production yield.
2. Strengthening Package Sealing
Many crystal oscillators use sealed packages, and tiny gaps may be left during production. The pressurized liquid can fill these gaps and repair sealing defects. Improved sealing prevents external moisture and corrosive gases from entering the package, protects internal components from oxidation, and extends service life.
3. Optimizing Electrical Parameters
Some specially formulated pressurized liquids contain compatible chemical components that react mildly with the crystal oscillator surface during treatment, adjusting core electrical parameters such as capacitance and inductance to better meet design requirements. After treatment, frequency accuracy and operating stability are improved, making the devices more suitable for high-end electronic equipment.
For custom fixtures or immersion trays used in the pressurized liquid treatment process, Hansheng Automation can provide precision machining based on customer drawings or samples.
