As we all know, in the ddust-free workshop cooling, we need to maintain the 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 does not meet the relevant standards, it will easily lead to the dust-free workshop unable to meet the environmental standards required for product production. So do you know the humidity standard of dust-free workshop refrigeration is how much? Let Jin Cheng answer it for you!

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 on temperature and humidity. Firstly, it is mainly for the solder paste to work in a better environment. Temperature will affect the activity of the solder paste and the related solvent activity of the flux added in it. High temperature will increase its activity, and ultimately affect the effect of silk screen mounting and reflow. It is easy to appear virtual welding, non-glossy solder joints and other phenomena. The size of the humidity back to cause the solder paste in the air to inhale the amount of water, such as over suction such as too much water, will make the reflux air, fly gradually, welding and other phenomena.

2. Biological manufacturing workshop

Temperature and humidity standards: The relative humidity ranges from 45% to 65% when the temperature ranges from 18 degrees to 26 degrees without special requirements

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

3. Manufacturing workshop of electronics industry:

Temperature and humidity: The temperature is about 22 ° C, and the relative humidity is 55 to 60%RH

Because electronic products in the manufacturing, production process of indoor air environment and quality requirements are very strict, mainly to the control of 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. You need to get rid of static and make people feel comfortable.

4. Food and beverage manufacturing workshop:

Temperature and humidity standard: The relative humidity should be less than or equal to 50%RH

Food dust-free workshop has a relatively high cleanliness requirement, usually 100,000 to more than 10,000, but at the same time, the lower the humidity of the workshop, the more likely it is to breed bacteria, bacteria and other biological pollution (mold, virus, fungus, mites) in the relative humidity of more than 60% of the environment can actively reproduce. Some flora can grow at relative humidity of more than 30%. Relative humidity in the 40 to 60 per cent range can reduce the effects of bacteria and respiratory infections to very low levels.
