With social development and technological progress, connectors are playing an increasingly important role in various fields. In order to ensure their safety, durability and other performance, it is essential to test connectors. In addition to the conventional continuity test, other test items are required depending on the final application environment of the connector. Among them, the high pressure cooking (HAST) test is to test the environmental resistance of the connector in a humid and hot environment by setting a high temperature, high humidity, and high pressure environment to accelerate the penetration of moisture through the external protective material or sealant or between the external material and the conductor.
The test parameters of high pressure cooking equipment are generally set as: temperature range: 105℃～142.9℃, humidity range: 75%～100%RH, air pressure range: 0.1～0.296Mpa. The test standards are: JESD22-A102-C-2000 Accelerated Humidity Resistance Test (Unsaturated Air Pressure), JESD22-A110-B-1999 Highly Accelerated Temperature Humidity Stress Test. Moisture not only easily leads to corrosion of the contact parts and affects the contact performance, but also due to the thermal expansion and contraction of plastics, the product will swell during the cooking test, resulting in excessive size. Therefore, after passing the test and inspection, the connector can be more guaranteed in terms of performance and quality to ensure that it meets the needs of customer applications.
