Sure Electronics has been committed to provide customers with Safe, Unity, Reliable and Efficient audio products since its birth. With ten years’ experience accumulated in highly demanding applications, Sure Electronics has built a complete Test System with full set of test reports, covering all phases from development to shipment, making a strong endorsement for the reliability of our products.
HASS (Highly accelerated stress screen）is implemented in the production phase to ensure that all improvement measures found in HALT can be implemented and make sure that no new defects are introduced due to changes in production processes and components.
All products will be tested at -40℃- 65℃ in half output power for up to 1000 hours to provide validated MTBF data. Meanwhile, we will use the signal generator to sweep in the frequency range of 20Hz-20kHz and observe the output waveform. Only when the products pass all tests, can they be put in storage.
All of WONDOM products must pass the HASS test and can be used at -20℃-55℃ and -40℃- 65℃. The operation temperature for our standard products is -20℃-55℃. If customers if the customer needs products for the temperature range of -40℃- 65℃,please contact us and we will also provide the corresponding test report.
