Newly introduced High Accelerated Stress Test (HAST CHAMBER) equipment! Accelerated life tests, including the pressure cooker test, are now possible.
By significantly increasing the vapor pressure in the test chamber above the vapor pressure of the moisture inside the sample, the intrusion of moisture into the sample can be accelerated, allowing for a quicker evaluation of moisture resistance. The pressure cooker test is conducted in an environment with temperatures above 100°C and a high-density water vapor atmosphere. 【Scope of Application】 Small electronic components, primarily those that are not hermetically sealed. However, it does not aim to evaluate effects occurring on the surface of the sample, such as corrosion or deformation. 【Test Overview】 - An electrical bias is usually applied to the sample. - The test conditions should be carefully selected, as they can significantly impact the failure modes that occur in the specimen. - The tests are conducted at a relative humidity of 85% across three different temperature levels. The severity of the test is defined by the duration of each test.
