MIL-PRF-38534 SANWOOD Technology Highly Accelerated Stress Test Chamber: Ensuring Semiconductor Reliability

SANWOOD Highly Accelerated Stress Test Chamber helps semiconductor reliability testing under extreme conditions per MIL-PRF-38534.

In the semiconductor industry, long-term product reliability is a key indicator of a product's value. Verifying device lifespan under natural conditions takes years, which cannot meet today's rapidly iterating R&D and production cycles. SANWOOD Technology's Highly Accelerated Stress Test Chamber simulates extreme environments of high temperature, high humidity, and high pressure, accelerating the aging process within the laboratory. It can accurately assess potential issues such as packaging integrity, electrical performance degradation, and material deterioration in semiconductor devices after long-term service within days or weeks, providing crucial data support for product durability.

HAST aims to accelerate qualification: quickly identify defective designs or processes for research and development and certification. Compared to traditional constant temperature and humidity testing, HAST introduces high-pressure saturated water vapor to create a more rigorous testing environment, reducing testing time from thousands of hours to hundreds or even tens of hours without causing unrelated failures.

MIL-PRF-38534 is a high-performance and reliability specification developed by the U.S. Department of Defense for hybrid microcircuits. It does not specify concrete design and manufacturing details, but rather establishes a rigorous certification and quality assurance system to ensure that manufacturers' production lines are capable of consistently producing highly reliable products that meet the requirements of extremely demanding environments.

Parameters of SANWOOD Technology's Highly Accelerated Stress Test Chamber
SANWOOD Technology's Highly Accelerated Stress Test Chamber can be customized according to customer requirements. The basic technical parameters are as follows:
Temperature Range: +105℃～+133℃
Humidity Range: 65% RH～100% RH
Pressure Control Range: 0.5~2.3kg/cm² (0.05~0.23Mpa)

Features of the SANWOOD Technology Highly Accelerated Stress Test Chamber:
1. It can maintain water vapor in a liquid or unsaturated state even at temperatures exceeding 100℃, thus creating a high-temperature and high-humidity environment.
2. It records temperature, humidity, and pressure curves during the test and can export the data to an Excel file via USB flash drive for easy traceability and analysis. It supports data transmission via Ethernet and RS-485 communication interfaces.
3. HAST test conditions include 130℃, 85%RH, 230KPa atmospheric pressure, and a 96-hour test duration.
