Standard wooden case

steam equipment/hast testing chamber Hast high pressure accelerated aging

Main Function

HAST test is generally called pressure cooker cooking test or saturated steam test. The most important thing is to test the test object under severe temperature, humidity (75%~100%RH) [saturated water vapor] and pressure environment. The product is resistant to high humidity, for printed circuit boards & FPC), for material moisture absorption test, high pressure cooking test, etc. For testing purposes, if the test object is a semiconductor, to test the moisture resistance of the semiconductor package, wait The test item is tested under the harsh temperature and humidity and pressure environment. If the half package is not good, the moisture will penetrate into the package along the interface of the colloid or colloid and the lead frame. Common causes of the cause: explosion effect, Corrosion caused by corrosion in the metallization area, short circuit caused by contamination between the pins of the package, etc.

Main feature

1. The imported double-temperature structure with high temperature resistant solenoid valve is used to minimize the failure rate.

 2. Independent steam generation chamber to avoid direct impact of steam on the product, so as not to cause partial damage to the product.

 3. The door lock labor-saving structure solves the shortcomings of the locking difficulty of the first-generation product disc handle.

 4. Cool air before the test; the design of the exhaust air in the test (air discharge in the test barrel) improves the pressure stability and reproducibility.

 5. Ultra long-term experimental running time, long time experimental machine running 1000 hours.

 6. Water level protection, through the test indoor water level Sensor to detect protection.

7.tank pressure design, the box body pressure (140 ° C) 2.65kg, in line with the water pressure test 6kg.

8. Two-stage pressure safety protection device, adopting two-stage combined controller and mechanical pressure protection device.

9.Safety protection button, emergency safety device, two-stage automatic pressure button

10. Support USB export data, history record three months of test data.
