Electronic industry

For electronic products and various household appliances, various quality problems caused by moisture have become the main reasons for manufacturers' production difficulties and the decline in product yield rates.It is very harmful to the electronics industry.

Moreover, this kind of harm is invisible to the naked eye, and even if professional equipment is used for detection, it is still very difficult to discover and determine.

It can only be manifested during the usage process. Therefore, if it is desired to ensure the smooth production of electronic products and that the product quality is not affected by moisture, it is necessary to do a good job in preventing moisture both during production and storage.  

Then how does humidity affect the production and storage of electronic products?

Firstly, during the production process, the harm of humid air to the semiconductor industry is mainly manifested in that moisture can penetrate through the plastic packaging and invade the inside of integrated circuits (ICs) from gaps such as pins, resulting in a moisture absorption phenomenon. During the heating process of the surface mount technology (SMT), water vapor is formed, and the pressure generated causes the resin packaging of ICs to crack, which leads to the oxidation of the metal inside IC devices and then product failures. In addition, when components are being soldered to the printed circuit board (PCB), the expansion of moisture due to heat can also cause poor soldering. Besides, humidity also has an impact on electronic components such as capacitors, switches, connectors, ceramic components, solder, PCBs, crystals, LEDs, and silicon wafers, reducing the yield rate.

Secondly, during storage, the outer packaging of electronic products is prone to corrosion, and the failure rate of the products increases significantly.

So, how can we ensure that the production and storage of electronic products are not affected by humidity?

The solution is to equip the production workshops and warehouses of electronics factories with the Shiman industrial dehumidifier series for moisture prevention and dehumidification. The Shiman dehumidifier adopts the refrigeration dehumidification technology. It can suck the humid air into the machine body, and after passing through the condensing system composed of a compressor, a condenser, and an evaporator, the moisture in the air is condensed into water and discharged, while dry air is blown out at the same time. Through continuous circulation in this way, the air humidity can be reduced. Meanwhile, the microcomputer control system can control the air humidity in the workshops and warehouses within the range of 45 - 60% relative humidity (RH) according to the input air humidity value, ensuring that the production and storage of electronic products are not affected by humidity.
