High Accelerated Life aging Testing Machine

The High Accelerated Life Aging Test Machine, also known as the High Pressure Accelerated Aging Chamber, is a reliability testing device that simulates the long-term aging process of products through the combined application of high temperature, high pressure, and high humidity stresses.

Core Features

Dual-channel control: Supports dry and wet bulb temperature control, as well as saturated/unsaturated mode to prevent sample condensation.
Fast response： Can rapidly increase temperature and pressure to 130℃/85% RH/0.2MPa.
Automatic water supply： Equipped with automatic water replenishment and water quality filtration to protect the pipeline.
High-pressure safety： Circular pressure-bearing chamber， pressure interlock automatic door lock, multiple pressure relief protection.

Standards Compliance

JESD22-A110 / A118

IEC 60068-2-66

ASTM G154 / G15

Safety Features

Electronic lock: Automatically mechanically locked when pressure inside the box is to high
Overpressure protection: Secondary mechanical pressure relief valve + electronic pressure relief alarm
Anti-dry-burning: Automatically alarms and stops when there is insufficient water
Leakage protection: Ensures the safety of operators

What are "saturated mode" and "unsaturated mode"? How to choose?

Saturation mode: The humidity is maintained at 100% RH, suitable for PCT high-pressure accelerated aging tests. Non-saturation mode: The humidity can be adjusted (e.g. 85% RH), suitable for testing of electrically charged electronic components, avoiding the occurrence of condensation water that may cause false short circuits.

.What are the differences between the HAST test and the traditional 85/85 test (the double 85 test)?

The traditional 85/85 test (at 85℃/85%RH) is an unpressurized test and takes approximately 1000 hours. HAST enhances the steam permeability through pressurization, achieving the same failure effect in only 96 to 168 hours, significantly shortening the research and development cycle.

What are the requirements for water quality?

The HAST test has extremely strict requirements for water quality. Deionized water with an electrical conductivity of less than 5 μS/cm must be used, which can effectively prevent electrode corrosion and pipe scaling.
