FAQ

(1) How does the Smartwatch Leak Tester detect micro-leakage?

The tester applies controlled pressure (positive, negative, or differential) to the smartwatch and monitors pressure changes over time. Even very small pressure deviations indicate leakage, allowing accurate detection of sealing defects.

(2) What parts of a smartwatch can be tested?

It can test key sealing areas such as housing joints, buttons, display bonding areas, sensor windows, charging contacts, and speaker vents, covering both components and fully assembled products.

(3) Which testing method is most suitable for smartwatches?

The differential pressure method is commonly preferred due to its high sensitivity and accuracy in detecting micro-leakage in compact and complex smartwatch structures.

(4) Why is leak testing essential for smartwatches?

Smartwatches are exposed to water, sweat, and environmental moisture. Leak testing ensures proper sealing, prevents internal damage, and improves product reliability and lifespan.

(5) Can this equipment be used in automated production lines?

Yes. The system supports multi-station operation, PLC control, and data communication interfaces, making it suitable for integration into automated manufacturing and quality control systems.
