Tin selection and re selection equipment

Tin selection and re selection equipment

Tin selection and re selection equipment is one of the essential equipment in the electronic manufacturing process. Its main function is to heat and cool the solder joints during the manufacturing process of electronic products, thereby completing the connection of electronic components. This article will provide a detailed introduction to the usage methods and operating steps of the tin sorting and re sorting equipment, to help readers better use this equipment.

1、 Basic principles of tin selection and re selection equipment

The basic principle of tin selection and re selection equipment is to use high temperature heating to melt solder joints, thereby connecting electronic components together. The tin selection and re selection equipment mainly consists of a heating system, temperature control system, welding platform, etc. When using tin selection and re selection equipment, the following points need to be noted:

1. Adjust the heating temperature

The adjustment of heating temperature for tin selection and re selection equipment is very important, as high or low temperature can affect the quality of solder joints. Generally speaking, the melting point of the solder joint is around 220 ℃, so the heating temperature of the tin selection and re selection equipment should be between 200 ℃ and 250 ℃. If the temperature is too high, it is easy to burn out the solder joints; If the temperature is too low, the solder joint cannot melt and the connection cannot be completed.

2. Control heating time

The heating time of the tin selection and re selection equipment is also very important. Generally speaking, the heating time should be between 2-3 seconds. If the heating time is too long, the solder joints are easy to burn out; If the heating time is too short, the solder joint cannot melt and the connection cannot be completed.

3. Control cooling time

The cooling time of the tin selection and re selection equipment is also very important. Generally speaking, the cooling time should be between 3-5 seconds. If the cooling time is too short, the solder joint is prone to fracture; If the cooling time is too long, it will affect production efficiency.

2、 Steps for using tin selection and re selection equipment

The following steps need to be followed when using tin sorting and re sorting equipment:

1. Preparation work

Before using the tin selection and re selection equipment, materials such as solder joints, electronic components, and solder wires need to be prepared. In addition, it is also necessary to check whether the heating system, temperature control system and soldering station of the tin concentrator and gravity concentrator are normal.

2. Heating solder joints

Place the solder joint on the soldering table and adjust the heating temperature and time of the tin selection and re selection equipment. During the heating process, it is necessary to pay attention to the condition of the solder joints to ensure that they are evenly heated.

3. Connect electronic components

After the heating of the solder joint is completed, place the electronic components on the solder joint and wait for the solder joint to cool. When connecting electronic components, it is necessary to pay attention to the direction and position of the electronic components to ensure correct connection.

4. Cooling solder joints

After the electronic components are connected, it is necessary to wait for the solder joints to cool down. During the cooling process, it is necessary to pay attention to the condition of the solder joints to ensure uniform cooling of the solder joints.

5. Check the connection quality

After the connection is completed, the connection quality needs to be checked. You can use tools such as a multimeter for testing to ensure good connection quality.

3、 Maintenance and upkeep of tin selection and re selection equipment

The maintenance and upkeep of the tin and heavy separation equipment is very important, which can extend the equipment's lifespan and improve production efficiency. The following are the maintenance methods for tin selection and re selection equipment:

1. Regular cleaning

The tin selection and re selection equipment needs to be cleaned regularly to remove impurities such as welding slag and solder wire. When cleaning, it is necessary to pay attention to safety and avoid burns.

2. Check the heating system

The heating system of the tin selection and re selection equipment needs to be regularly checked to ensure that the heating temperature and time are normal. If any abnormalities are found, they need to be replaced in a timely manner.

3. Check the temperature control system

The temperature control system of the tin selection and re selection equipment also needs to be regularly checked to ensure normal temperature control. If any abnormalities are found, they need to be replaced in a timely manner.

4. Check the welding table

The soldering platform of the tin selection and re selection equipment also needs to be regularly inspected to ensure that the soldering platform is flat and undamaged. If any abnormalities are found, they need to be replaced in a timely manner.

4、 Conclusion

Tin selection and re selection equipment plays an important role in the electronic manufacturing process. This article introduces the basic principle, usage steps, and maintenance methods of the tin sorting and re sorting equipment, hoping to be helpful to readers. When using tin selection and re selection equipment, it is necessary to pay attention to safety and ensure correct operation to ensure production efficiency and product quality.
