HAST Highly Accelerated Stress Test Chamber
HAST Highly Accelerated Stress Test Chamber is suitable for IC packaging, semiconductors, microelectronic chips, magnetic materials, and other electronic parts for high pressure, high temperature, unsaturated/saturated humidity heat, and other accelerated life reliability tests. It is utilized in the product design phase to rapidly reveal product defects and weaknesses, as well as to assess the tightness and aging performance of the products.
Application
The high and low-pressure humidity heat testing chamber is suitable for IC packaging, semiconductors, microelectronic chips, magnetic materials, and other electronic parts for high pressure, high temperature, unsaturated/saturated humidity heat, and other accelerated life reliability tests. It is utilized in the product design phase to rapidly reveal product defects and weaknesses, as well as to assess the tightness and aging performance of the products.
Sample restrictions
Testing and storing samples of flammable, explosive, and volatile substances. Testing and storing samples of corrosive substances. Testing or storing biological samples. Testing and storing samples of strong electromagnetic emission sources.
Sample requirements
To ensure your test data is authentic and effective, it's essential to adhere to the following principles when using the test chamber:
1. The total mass of the load should not exceed 80 kilograms per cubic meter of studio volume.
2. The total volume of the load should not exceed one-fifth of the volume of the working room.
3. In any section perpendicular to the prevailing wind direction, the total load area should not surpass one-third of the cross-sectional area of the working chamber.
4. Avoid obstructing the airflow when placing the load.
