[What are the humidity requirements for dust-free space refrigeration]
Release date:[2023/12/14] Is reading[162]次

In the dust-free workshop cooling, it is necessary to maintain a balance between temperature and humidity in order to meet the environmental requirements of the production process. Otherwise, if the temperature and humidity of the dust-free workshop cooling do not meet the relevant standards, it will easily lead to the failure of the dust-free workshop cooling to meet the environmental standards required for product production. So do you know the humidity standard of clean workshop refrigeration is what?


Temperature and humidity standard of dust-free workshop:

1. SMT workshop

Temperature and humidity standard: Temperature: 24±2 ° C Humidity: 50±10%

SMT workshop has clear requirements for temperature and humidity, first of all, mainly for the solder paste to work in a better environment, the temperature will affect the activity of the solder paste, which has a certain impact on the activity of the related solvent of the flux added inside. The high temperature will increase its activity, and ultimately affect the effect of screen printing and reflow, and it is easy to appear virtual welding, and the solder joint is not shiny. The size of the humidity will cause the amount of water vapor inhaled by the solder paste in the air, such as over suction such as too much water vapor, which will cause air, flying, welding and other phenomena during the reflux.


2. Biological manufacturing workshop

Temperature and humidity standard: In the absence of special requirements, at 18~26 degrees, the relative humidity is controlled at 45%~65%

The biological manufacturing workshop is a room (area) that needs to control dust particles and microbial pollution in the environment, and its building structure, equipment and use have the function of preventing the introduction, production and retention of pollutants in the area.


3, electronics industry manufacturing workshop:

Temperature and humidity standard: The temperature is controlled at about 22 ℃, and the relative humidity is controlled at 55 ~ 60%RH

Because electronic products in the manufacturing, production process of the indoor air environment and quality requirements are extremely strict, mainly to control particles and dust as the main object, but also to the temperature and humidity of the environment, the amount of fresh air, noise and so on have made strict regulations. Need to eliminate static and make people feel comfortable.


4. Food and beverage manufacturing workshop:

Temperature and humidity standard: The relative humidity should be controlled within 50%RH

The clean food workshop has a relatively high cleanliness requirement for production, usually 100,000 to more than 10,000, but at the same time, the lower the humidity of the workshop, the easier it is to breed bacteria, bacteria and other biological pollution (mold, virus, fungus, mites) can actively reproduce in an environment with relative humidity of more than 60%. Some bacterial communities can grow at relative humidity of more than 30%. When the relative humidity is in the range of 40% to 60%, the effects of bacteria and respiratory infections can be reduced to a very low level.
