Product Introduction
The purpose of HAST accelerated life test is to increase environmental stress (such as temperature) and working stress (voltage, load, etc. applied to the product), speed up the test process, and shorten the life test time of the product or system. It is used to investigate and analyze when the problems of wear and service life of electronic components and mechanical parts occur, what is the shape of the failure distribution function of service life, and the test to analyze the reasons for the increase in failure rate
Scope of application
HAST aging test chambers are widely used in IC semiconductors, connectors, circuit boards, magnetic materials, polymer materials, EVA, photovoltaic modules and other related products for accelerated aging life testing.
Features:
1. The dual-circuit structure of imported high temperature resistant solenoid valve reduces the use failure rate to the greatest extent.
2. Separate steam generation room to avoid direct impact of steam on the product, so as not to cause partial damage to the product.
3. The labor-saving structure of the door lock solves the shortcomings of difficult locking of the disc handle of the first generation product.
4. Exhaust cold air before the test; the design of cold air exhaust during the test (the air in the test barrel is discharged) improves the pressure stability and reproducibility.
5. Ultra-long-term experiment operation time, long-term operation of the experiment machine for 400 hours.
6. Water level protection, through the water level Sensor in the test room to detect and protect.
7. Tank pressure-resistant design, the box body can withstand pressure (150℃) 2.65kg, which meets the water pressure test 6kg.
8. Two-stage pressure safety protection device adopts a two-stage combination controller and mechanical pressure protection device.
9. Two-stage automatic pressure-relief button for safety protection and emergency safety device.
10. The withstand voltage of the bias test terminal can reach 3000V (optional)
11.USB export history data and curves.
