Why samples need to do HAST aging test?
JESD22-A110E Standard High Humidity High Pressure Testing Chamber is a type of environmental chamber used to test the reliability and durability of electronic components and products under extreme conditions. The function of a HAST chamber is to accelerate the aging process of a product by subjecting it to high temperature and high humidity conditions.
During the HAST test, the product is placed in a sealed chamber that is heated to a high temperature, typically between 110°C to 130°C, and exposed to a high humidity environment, usually around 65% to 100% relative humidity (RH). The high temperature and humidity levels cause the materials and components of the product to expand and contract rapidly, which can accelerate the aging process and reveal any weaknesses or failures.
The HAST test is a useful tool for manufacturers to evaluate the long-term reliability and durability of their products, as well as to identify potential design flaws or weaknesses that could lead to product failure in the field. By subjecting the product to accelerated aging conditions in a HAST chamber, manufacturers can simulate years of use in a matter of days or weeks, helping them to develop more robust and reliable products.
