Many customers don’t know how to choose when purchasing. In this issue, we will introduce to you the differences between tunnel furnaces for the food industry and PCB circuit board tunnel furnaces for electronic products. I believe that through the content of this issue, no matter which industry you belong to, you will be able to choose. It can have a certain reference value. From the perspective of the process requirements for food tunnel ovens and the process requirements for drying electronic product PCB circuit boards, the food and electronics industries have some special or different requirements when purchasing tunnel ovens. The following are some related comparisons and analyses:
1. The difference in temperature control requirements of tunnel furnaces:
1. Food industry: In order to prevent food from being scorched due to overheating, or the temperature not reaching the standard, and not being crispy enough, and to ensure the taste quality of the food and the food safety requirements for sterilization and sterilization of some foods, the normal temperature control error must be maintained within ±3 degrees Celsius.
2. Electronics industry: PCB circuit board is a high-end precision manufacturing industry. Especially with the development of miniaturization and integration of electronic products, the requirements for PCB production accuracy are also increasing, and the requirements for temperature control are becoming more stringent because the temperature difference is very large. It may lead to poor quality PCB boards and cause damage. Usually, the temperature control requirement of most conventional circuit boards is within ±3 degrees Celsius, and high-end circuit boards may need to reach ±1~2 degrees Celsius.
2. Differences in humidity control requirements of tunnel furnaces:
1. Food industry: Due to the particularity of the food industry, drying does not necessarily pursue complete dehumidification. It may need to maintain a certain amount of moisture, so the humidity control requirements are relatively high, but this is not a difficult requirement. Basically, current control systems can achieve this.
2. Electronics industry: The humidity control requirements of PCB circuit boards are not as high or complex as those of the food industry, and there are relatively mature process requirements management.
3. Differences in cleanliness requirements of tunnel furnaces:
1. Food industry: In addition to the materials and other aspects of the contact between food and tunnel ovens, the gas and other substances generated during the baking process also need to comply with relevant standards to ensure that the food will not be contaminated and meet safety standards. Secondly, the food tunnel oven It needs to be easy to clean and maintain and have functions such as dustproof and antibacterial.
2. Electronics industry: Based on the use and process characteristics of PCB circuit boards, the circuit board tunnel oven only needs to ensure that the boards will not be polluted and damaged during the production process. It is usually equipped with a thousand-level air filtration system. The specific requirements are based on different conditions. Manufacturers and product needs vary.
4. The difference in production efficiency requirements of tunnel furnaces:
1. Food industry: The food industry is the most typical industry that requires large quantities and high production speed, and the production and processing process is relatively simple. Therefore, the food tunnel furnace has higher requirements for production speed and energy efficiency, which directly affects the production cost and price. Competitiveness.
2. Electronics industry: Compared with the food industry, the production processes of electronic industry products such as PCB circuit boards are more complex and require higher precision. They are also limited by the production speed of other links. The production efficiency requirements of tunnel furnaces in the electronics industry are relatively easy. Compared with production efficiency, tunnel furnaces in the electronics industry have higher requirements for yield rate, intelligence, less personnel, and energy saving.
5. Differences in safety requirements of tunnel furnaces:
Safety requirements are important no matter which industry you are in. The common ones are fire and explosion protection safety, operation safety, maintenance safety, electrical safety, emission safety, etc.; secondly, the food industry needs to pay extra attention to food safety, etc.
