The structural characteristics of the electronic purification engineering workshop In the production process of electronic products, the environmental temperature, humidity, cleanliness and pressure gradient will have a greater impact on the quality of electronic products. Therefore, it is necessary to have good thermal insulation and airtightness, which is also reflected in the structure of the purification workshop. The structure must be as close as possible. The gap in the structure will provide convenience for air convection and affect the temperature and pressure gradient control in the workshop; secondly, the material and structure of the workshop must be as good as possible to achieve good thermal insulation effects, such as polyurethane, aluminum Honeycomb, polystyrene, paper honeycomb, etc. as the structure of the sandwich layer can play a good thermal insulation effect.
