The essence of thermal aging is to accelerate the oxidation reaction process, while maintaining a supply of fresh air while accurately controlling temperature.

1、 aging test

Aging tests can be used to speculate on product service life, screen and optimize process plans, study failure mechanisms, and evaluate process flows. Widely used in industries such as industrial mines, plastic textiles, and automotive testing.

For oven aging technology, the influence of temperature on the aging process is often non-linear, and the higher the temperature, the faster the corresponding chemical reaction rate. Therefore, it is necessary to study the impact of temperature, and temperature aging is also an important component of aging research.

As an aging test in highly regulated industries, there are generally corresponding standards for reference and adherence. For example, in the field of environmental testing instruments, there are GB/T32710.11-2016 air aging test chambers, and in the field of electrical insulation materials, there are GB/T11026 series standards.

2、 Temperature regulation and ventilation

Temperature control performance is a fundamental parameter that cannot be ignored. The temperature range used in different application fields varies, ranging from 50 to 105 ℃ in the medium to low temperature range to nearly 300 ℃ in the high temperature range. Accurate temperature control is necessary. The decisive factor of the thermal aging test is oxidation, which consumes oxygen in the air. Therefore, in order to maintain the continuous progress of the aging test, fresh air needs to be continuously supplemented, that is, there are different requirements for air change rate or Air changes per hour.

At the same time, Natural convection and Forced convection should be carried out, corresponding to the natural gravity convection and forced ventilation convection in the standard. When conducting the aging test for the operating conditions of the clean ovens, the matching between the volume and the air exchange rate should still be considered, and appropriate optimization should be carried out.

In general, the clean oven?is a test equipment that uses air as the medium to control the temperature and air exchange rate. It is mainly used for the pre-treatment baking of silicon chips, gallium arsenide, Lithium niobate, glass and other materials before gluing, curing of hard films after gluing and high-temperature baking after developing in semiconductor manufacturing; It is also suitable for production and research departments such as electronic liquid crystal displays, LCDs, CMOS, IS, pharmaceuticals, laboratories, etc; It can also be used for other high-temperature tests such as drying, heat treatment, aging, etc. of non volatile and non flammable and explosive materials, to assess and judge the adaptability of test samples to storage and use under high-temperature environmental conditions.
