The structure of unsaturated high -voltage acceleration aging test machine > The following requirements should be met: >
1. Can generate the temperature and relative humidity specified in the relevant requirements, and maintain the pressure value of the given;
2. It can provide controlled temperature, relative humidity, and relative humidity and relative humidity during the test period. Pressure and other conditions, and can increase or decrease to the prescribed experimental conditions according to the required slope;
3. The detection of sensitive devices in other areas (such as steam generators) that can give the same result (such as steam generator);
4. You can use water steam to discharge the air in the closed space from the air steam before the test starts. Outside;5. Substation water droplets are not allowed to fall on the test sample;
6. The structural materials used should not cause test samples Corrosion, or deteriorate the water quality of humidification. >
in the test box and test samples in the laboratory temperature Under pressure and humidity conditions, the test sample is installed into the working space of the test box. >The positioning and installation of the test sample:
Test sample should not be heated from heating The influence of radiation fever in the wall of the box.
If there are requirements for relevant specifications, a special installation device should be used. The thermal conductivity and thermal capacity of the installation fixture should be low enough, so that the test sample is insulated for all actual use.
Pay attention to the selection of materials for installing the installation and the installation fixture to reduce the action of pollutants to low, and reduce the influx of corrosion and other mechanisms to low.
1: Product introduction: >
Unsaturated high -voltage accelerated aging test machine > is mainly to test the moisture capacity of semiconductor packaging.Under the temperature, temperature and pressure test, the humidity will seep the human packaging body along the interface of the colloid or the collagen and the wire. Short circuit and so on. It is to accelerate the penetration of external protection materials or sealing agents or external materials and conductors. It is completed by continuously applied pressure under the set temperature and humidity conditions.
