Thermal cycling and damp heat test is a test method used to evaluate the performance and reliability of products in humid and hot alternating environments, such as outdoor electronic equipment in the summer of high temperature and humidity, low temperature and dry winter, and in different areas of transportation, storage encountered temperature and humidity changes, which is why the cyclic wet heat test is carried out.
According to IEC 60068-2-30 standard, a cycle usually sets the high temperature and humidity stage to 40℃, relative humidity 93%, and the duration is 12 hours; The low temperature stage is 25℃, the relative humidity is 85%, and the duration is 1 hour. The heating rate is about 1℃/min, the cooling rate is about 0.5℃/min, and the humidity change has the corresponding stable time requirements.
The LIB climate chamber can perform this test with an extremely wide and diverse temperature selection range: -20 ° C, -40 ° C and -70 ° C to 150 ° C, and humidity can be accurately controlled from 20% to 98%RH. The interior is equipped with strong air circulation fans and well-designed air ducts to ensure uniform temperature and humidity throughout the box and eliminate local differences. There is also a high-precision temperature and humidity sensor, real-time feedback data, to achieve accurate regulation.
For thermal cycle wet heat test using the LIB climate chamber, the product should be put into the work room according to the regulations and run according to the established procedures. The LIB test chamber has the function of test programming, and a standard cycle usually covers: heating and humidification, rising to the high temperature and high humidity setting value within a specified time; Maintain high temperature and high humidity, so that the product is fully "soaked" in it; Cooling and dampness, according to the rate requirements to low temperature and low humidity; Maintain low temperature and low humidity to check the performance of the product at this time.
LIB climate chamber's powerful temperature and humidity control function and user-friendly programming design make it the best helper for thermal cycle wet heat testing. LIB is a manufacturer with more than 26 years of experience in the production and design of test chambers, and has the production capacity of manufacturing standardized and customized test chambers. The comprehensive after-sales policy allows you to use climate chamber without worries.
