Hast High Pressure Accelerated Aging Testing Machine

The Highly Accelerated Aging Test (HAST) serves as an intensified environmental stress testing method, designed to amplify the product's exposure to environmental factors like temperature, as well as operational stresses such as voltage and load. This approach accelerates the testing timeline, allowing for a more rapid assessment of a product's or system's life cycle under conditions that would typically take much longer to manifest in real-world use.

The goal of HAST is to enhance the reliability of semiconductor products by subjecting them to conditions that are more severe than what they would encounter during regular operation. Most modern electronic devices are capable of enduring prolonged exposure to high temperatures and humidity without succumbing to failure, which has consequently led to an increase in the duration of tests required to validate the quality of finished products.

During the product's design phase, HAST is instrumental in swiftly uncovering any potential defects and vulnerabilities. It is particularly effective in evaluating the sealing integrity and the long-term aging performance of products, ensuring that they can withstand the rigors of their intended use over time. By doing so, HAST plays a critical role in the development process, allowing manufacturers to refine their products to meet the highest standards of durability and reliability.

features
1.  The system features an automatic water replenishment function, which seamlessly refills the water reservoir during testing in the event of a shortage, ensuring uninterrupted operation.

2.  For temperature regulation, the unit is equipped with an LED digital temperature controller, enabling precise setting, control, and display of the test environment's temperature.

3.  An LED digital timer is integrated, which initiates the countdown once the internal chamber's temperature reaches the preset value, guaranteeing that the test duration is accurately measured.

4.  The equipment maintains precise atmospheric conditions, with a temperature chart that consistently monitors and displays the internal pressure and relative humidity.

5.  An automatic water discharge mechanism is in place to prevent the release of non-saturated steam, ensuring optimal steam quality for the testing environment.

6.  The chamber is fitted with a one-piece silica gel door gasket, ensuring excellent air-tightness and extending the operational lifespan of the unit.
