How to use the constant temperature and humidity test chamber for semiconductor components

Semiconductor components constant temperature and humidity test chamber is a kind of equipment used to simulate semiconductor components in constant temperature and humidity conditions for testing and evaluation. Its role is mainly for semiconductor components for hot and humid storage, high temperature and high humidity test, these tests will generally use the semiconductor components constant temperature and humidity test chamber.
1. Semiconductor components constant temperature and humidity test chamber in the practical application of the following standards will be involved:
(1) GB / T 4937.42-2023 semiconductor devices mechanical and climatic test methods Part 42: temperature and humidity storage
(2) IEC 60749-42:2014
(3) JEDEC JESD22-A100E:2020 Cyclic Temperature-Humidity-Deviation and Surface Condensation Life Tests
(4) JEDEC JESD22-A101D.01:2021 Steady-state temperature-humidity deviation life test
(5) EIAJ ED-4701 100:2001 Environmental and Durability Test Methods for Semiconductor Devices
2. The following combination of semiconductor components constant temperature and humidity test chamber, to talk about some of the relevant tests.
(1) in the "GB / T 4937.42-2023 semiconductor devices Mechanical and Climatic Test Methods Part 42: Temperature and Humidity Storage" standard, you need to place the semiconductor device in the test chamber to do the following tests:
a. 40℃, 90%RH, continuous 8000h storage test.
b.60℃, 90%RH, continuous 4000h storage test.
c. 85℃, 85%RH, continuous 1000h storage test.
(2) In the standard "JESD22-A100D Steady State Temperature-Humidity Deviation Life Test," the following tests are required
Test time:1008 (-24, +168) hours;
Test temperature:30~65℃, but only reside at 65℃;
Test humidity:90%~98%RH;
Rate of temperature change:8.75℃/h~17.5℃/h.
The above two standards in the test, in the use of semiconductor components constant temperature and humidity test chamber, only need to place the test product in the test chamber, in the controller set the temperature, humidity, test time, you can automatically carry out the test. If you have any questions about the test, or constant temperature and humidity test chamber selection questions, you can visit the "Huanyi instrument" website, consult the relevant technical staff.
