When the dough kneading machine is working, the humidity is high, and water vapor can easily invade the industrial control circuit board, affecting its normal operation. Therefore, through material selection, structural design, protection process and other aspects of anti-humidity technology, the circuit board can be guaranteed to work stably in a humid environment.
The moisture-proof performance of the material is the basic line of defense against moisture. In the dough kneading machine industrial control circuit board, the selection of electronic components is crucial. Components with moisture-proof properties are preferred, and their packaging materials can resist the penetration of water vapor and prevent the internal chip from being damaged by moisture. For the substrate of the circuit board, a material with strong moisture resistance is used to reduce the erosion of moisture on the circuit board from the root. These materials not only have good moisture-proof ability themselves, but also can be better combined with subsequent protection processes to form a multi-layer protection system, providing basic guarantees for the stable operation of the circuit board in a humid environment.
The overall structural design of the circuit board is an important means to resist moisture. Optimize the layout and reasonably plan the location of electronic components to avoid water vapor accumulation due to unreasonable layout. Increase the spacing between components to reduce the risk of short circuit caused by condensation of water vapor in a small space. At the same time, a reasonable water guide groove or drainage channel is designed so that the water that accidentally enters the circuit board can be discharged in time to prevent the accumulation of water from damaging the circuit board. Through scientific structural design, the impact of the humid environment on the circuit board is reduced from the physical level, and its adaptability in a humid environment is enhanced.
Protective coating technology plays a key role in moisture resistance. Applying moisture-proof coating on the surface of the circuit board is a common and effective method. These coatings can form a dense protective film on the surface of the circuit board to isolate the circuit board from the external humid air. Different types of protective coatings have different characteristics. Some coatings have good flexibility and can adapt to the slight deformation of the circuit board during operation; some have higher hardness and can resist a certain degree of physical impact and wear while maintaining good moisture resistance. By precisely controlling the thickness and uniformity of the coating, every corner of the circuit board is ensured to be fully protected and effectively block the intrusion of water vapor.
Sealing technology further enhances the moisture resistance of the circuit board. The interfaces, slots and other parts of the circuit board are sealed, and sealing materials such as sealants and sealing rings are used to tightly seal these parts that are prone to water ingress. During the sealing process, ensure that the sealing material fits tightly with the circuit board and related components without leaving any gaps. At the same time, the overall packaging of the circuit board also adopts a sealing structure to make it difficult for external humid air to enter the inside of the circuit board. Through effective sealing measures, a relatively independent drying space is formed to create a good working environment for the circuit board, greatly reducing the possibility of moisture.
The cooperation of ventilation and drying systems can actively improve the working environment of the circuit board. A ventilation device is set inside the dough kneading machine to promote air circulation, accelerate the evaporation of water vapor, and reduce the humidity of the local environment. Combined with drying devices such as desiccant or dehumidification equipment, it further absorbs moisture in the air and keeps the air around the circuit board dry. Through the coordinated work of ventilation and drying systems, the environmental humidity of the circuit board is actively adjusted to reduce the impact of moisture on the circuit board and improve its reliability in humid environments.
Daily maintenance and monitoring mechanisms provide long-term protection for the circuit board's anti-humidity. Establish a regular maintenance system to inspect and clean the circuit board and promptly remove moisture and dirt that may accumulate on the surface. Install a humidity sensor to monitor the humidity of the environment around the circuit board in real time. Once the humidity exceeds the set threshold, an alarm is issued in time and corresponding dehumidification measures are taken. Through daily maintenance and real-time monitoring, potential moisture problems can be discovered and resolved in a timely manner to ensure that the circuit board is always in good working condition and extend its service life.
