In patch processing plants, we often see a lot of safety signs, such as static protection, electricity safety, prevention of pinching, and so on. For some other security points, we may rarely see them. Invisible does not mean there is no. For SMT chip processing plants, there are still many security protections that we need to understand. Let's take a look at them together.

1. Prevent chemical damage: Many kinds of chemicals or materials containing chemicals are used in the manufacturing process of electronic products, such as cleaning agents, fluxes, thinners, adhesives, fillers, solder pastes, etc. Therefore, strict training must be passed before operation, and the following requirements should be paid attention to during operation.
1. Chemicals should be stored in designated areas, far away from work areas, and above the specified safe distance, and safety facilities must be equipped.
2. When handling and using chemicals, you must wear protective equipment and operate in accordance with the operating procedures.
3. When chemical substances leak, corrode, or ignite, they must be operated in accordance with operating specifications and regulations to prevent accidents from expanding.
4. After the chemicals are used up, they must be operated in time according to the operating specifications and procedures, and put them back into the specified containers to prevent potential accidents.

2. Prevent gas shock: Many SMT equipments use high-pressure gas when they work or in a certain process. Therefore, pay attention to the following requirements during operation.

1. During the operation or debugging of the equipment, if an accident occurs, press the emergency stop button or pull down the power switch to make the equipment stop working immediately and turn off the air supply at the same time.
2. The air gun must be placed in the specified position with eye-catching warnings to prevent misoperation by others. When operating with an air gun, you must wear protective equipment and protective glasses, and you must operate in accordance with the operating specifications and regulations.

3. Visual protection: When many SMT equipment is working, the camera equipment or light source is constantly running. Therefore, pay attention to the following requirements during operation:

1. Do not stare directly at the light source during equipment operation, debugging and repair. Protect glasses if necessary.
2. As little as possible to open the doors and windows or protection of the equipment to prevent accidents.

4. Fire safety: Because many chemicals and certain packaging materials are used in the entire PCBA production process, and the warehouse of the factory contains a variety of flammable materials, all personnel entering the factory must establish fire prevention ideas. Fire prevention must be based on the principle of prevention. The following daily fire prevention common sense that patch processing plants need to pay attention to.
