Electronic components refer to the various functional components that make up electronic products. It usually has resistors, capacitors, inductors, or integrated circuit components composed of these small components. The quality of these components is the key to the function and life of electronic products. Most electronic products require operation and storage under dry conditions. According to statistics, more than a quarter of the world’s industrially manufactured defective products are related to the hazards of moisture each year. Electronic components and circuit boards are prone to false soldering during wave soldering after moisture absorption, which leads to an increase in the proportion of defective products. Although it can be improved after baking and dehumidification, the performance of vital parts is reduced after baking, which directly affects the product Quality, and the use of moisture-proof cabinets can effectively solve the above problems. So, what kind of moisture-proof cabinet can meet the storage needs of electronic components?
First of all, it is necessary to pay attention to the low humidity capacity of industrial moisture-proof cabinets. The storage requirement for electronic components is the need for a lower humidity environment. For MSD such as IC and BGA, it is necessary to rely on the IPC standard to meet the requirements of low humidity environment according to the humidity sensitivity level of MSD. Generally, a low humidity state below 10% RH is considered.
Secondly, pay attention to the humidity display accuracy of industrial moisture-proof cabinets. It is precisely because of the higher and higher requirements for the low-humidity capability of industrial moisture-proof cabinets, it also shows that the display accuracy is more important. If a humidity below 5%HR is required, but the display accuracy is -5%RH or higher, then this equipment basically cannot reach the requirement of 5%RH or higher. Generally, the display accuracy of industrial moisture-proof cabinets will be within ±3%RH, and even higher than ±2%RH.
Third, pay attention to the anti-static function of industrial moisture-proof cabinets. Related tests show that when the relative humidity is lower than 40% RH, static electricity is easily generated. Electrostatic discharge is the main cause of breakdown hazards of electronic components and interference to the operation of electronic equipment. The anti-static measures for general industrial moisture-proof cabinets include anti-static spraying and grounding on the surface of the cabinet. It should be noted that the anti-static spraying needs to be sprayed with anti-static powder, and should not be used in the form of anti-static paint to ensure long-term anti-static effect.
Fourth, the dehumidification speed of industrial moisture-proof cabinets. A big difference between the use of moisture-proof cabinets in industry and the use of traditional moisture-proof boxes is the increase in the number of door openings and closings. Traditional civilian moisture-proof boxes may not be able to open the door once in a few days. However, the use of moisture-proof cabinets in industry has greatly increased the number of door openings and closings. Therefore, it is necessary for the industrial moisture-proof cabinet to have a good dehumidification speed to ensure that the industrial moisture-proof cabinet can be in the required ultra-low humidity condition most of the time.
