Many industries need to use industrial dehumidifiers in industrial production, such as the production of the electronics industry. According to the national requirements and standards, combined with the actual situation of the IC plastic packaging production line, the range of temperature and humidity control has been determined for the relevant processes, and it has been operating for several years. The effect is good. The relative humidity of IC production is 45~55%RH under normal conditions. Need dehumidifier to control humidity.
When the humidity was abnormal at that time, the situation of the sticky film was described as follows: All the tables, chairs, benches, glass, equipment, wafers, chips, and the surface of the anti-static clothing on the human body had serious water vapor. The water vapor on the glass made the indoor people unable to see the aisles. When the hand touches the surface of the table and chair equipment, there are obvious fingerprints of finger water. What's more serious is that there are many chips stored on site during the bonding process. All of these products also include other series of products, which are like going through a "steam bath".
Afterwards, an ultrasonic scan was performed on the unqualified crystals in the cards with extremely high reject rates, and it was found that there were different degrees of delamination. After anatomy, it was found that there were cracks, gold wires broken, and cracks in some chips from the delamination. Finally, the conclusions are as follows: (1) The main reason for the decrease in yield is the cracks in the package separation layer, which leads to chip cracks or gold wire breakage. (2) The reason for the delamination is that the water vapor envelope on the surface of the chip is generated in the plastic package. This shows that temperature and humidity have a significant impact on IC packaging production.
Humidity problems caused by various reasons such as water quality and heat sources also often plague the normal operation of program-controlled computer rooms, computer rooms, and electronic workshops. This is only the demand for dehumidifiers in the electronics industry, and many other industries also need industrial dehumidifiers.
Why do industrial production need industrial dehumidifiers? Industrial dehumidifiers can solve the problem of excessive humidity in industrial production. The use of industrial dehumidifiers to control humidity provides a good working environment for industrial production, which plays an important role in improving product quality!
