In SMT chip processing and production, it is often necessary to take electrostatic protection measures for the assembly of electronic products to reduce damage to electronic products. The specific methods of electrostatic protection are：

(1) Reduce product friction

In the production line rotating device, it is necessary to reduce the slippage of the conveyor belt and other moving parts . The transmission belt should be tight enough to avoid overloading, and the selected belt should also use conductive tape or triangular tape with high rotation efficiency as much as possible, and conductive triangular tape with high transmission efficiency.

(4) How to eliminate the static electricity of the conductor

The static electricity on the conductor can be discharged to the ground by . In the anti-static process , the time required for static electricity to leak will be required within 1 s, and the voltage should drop to a safe area below 100V. Can prevent its leakage time is too short, leakage current is too large to cause damage to electrostatic sensitive devices.

(5) Elimination of non-conductor static electricity

For the static electricity on , since the charge cannot flow on the insulator , the grounding method cannot be used to eliminate the static electricity. Can be used ① use ion blower (gun). ② Use static eliminator. ③ Control the humidity of the environment. ④ Electrostatic shielding

The process control method lies in the need to take preventive measures in the process of material selection, installation and production operation, so as to control the generation of static electricity and the accumulation of charges, and try to reduce the static charge generated in the SMT production process, so as to achieve the purpose of reducing hazards.

In the process of SMT processing and production, the generation of static electricity is inevitable. We can reduce the protection of static electricity in various ways, and control the harm of static electricity within an effective range. In addition to the various methods mentioned above, it is also necessary to post some anti-static signs in the production workshop. It is also very important to regularly check the temperature and humidity of the workshop. Workshop personnel need to wear anti-static clothes bring a Anti-static wrist straps, etc., these are essential in the electrostatic protection system.
