Precautions for SMT patch processing and welding

SMT chip processing simplifies the production process of complete electronic products, effectively reduces the production cost, effectively shortens the whole production process, and improves the production efficiency. What are the precautions for SMT chip processing and welding? Let's take a look:

1. PCB board shall be properly processed before SMT chip processing, and ensure that the pads of components and circuit board are in weldable state.

2. During SMT patch processing, never let your hair and wires not twist together. Women with long hair should pay attention to this. During SMT patch processing, you need to wear an anti-static hat and tie up your hair.

3. Some employees with sweaty hands should wear gloves to avoid electric shock accidents.

4. The power plug of electric soldering iron shall be in contact with the socket to avoid loosening, damage and injury.

5. If the electric soldering iron is used every day, the power socket switch shall be used to control the power on and power off of the electric soldering iron, or a power switch shall be installed on the power line of the electric soldering iron to avoid loose plug and poor contact caused by frequent plugging.

6. During SMT chip processing, the welded joint shall not be immersed in flux for a long time, and other highly corrosive chemical industrial products shall not be used as flux.

7. Low power electric soldering iron sometimes can not reach the heat. If the welding time is too long, it is easy to burn electronic components. The electric soldering iron with slightly higher power can be selected with sufficient heat, which can reduce the processing and welding time of SMT patch and the heat received by the solder joint, but will not be damaged. Therefore, the choice of electric soldering iron also needs to be careful.

9. Note that there is a kind of solder paste (also known as solder oil) on the market. It is corrosive and is used in industry. It is not suitable for the welding of electronic products.

10. The integrated circuit shall be welded after the whole electronic product. The anti-static Bracelet shall be worn during SMT patch processing and welding, and the electric soldering iron shall be reliably grounded. You can also use an integrated circuit socket and insert the integrated circuit into it after welding the socket. This method is convenient for maintenance and replacement of frequently used chips with high damage frequency.

11. After SMT chip processing, the residual solder on the circuit board shall be wiped with alcohol to prevent carbonized solder from affecting the normal operation of the circuit.

12. After SMT chip processing and welding, turn off the power and clean the desktop.

13. After the electric soldering iron is frequently used for a period of time, the power cord needs to be replaced to prevent the root or internal fracture of the power cord.

The above explanation is the precautions for SMT patch processing and welding. I hope it will be helpful to you.
