In the SMT production line, we will encounter the problem of static electricity, from the friction between the clothes and the dry air to the dry air, which is the end of the duckweed. If the condition is suitable, it is a few volts and the peak is hundreds of kilovolts, so anti static is the need to do in our work, today, the south. Give some measures to introduce mechanical anti electrostatic patch SMT.

Static electricity has three: static clothing, antistatic shoes (conductive shoes), electrostatic hand rings, antistatic shoes and electrostatic hand rings to guide the human body to avoid accumulation in the human body.
Ordinary clothes will have great electrostatic voltage in the walk (>1000V). And antistatic clothing does not happen when it moves. This is the main role of antistatic clothing, long strip antistatic clothing can not shield the inside of the clothing produced static (after wearing still >1000V), grid – like antistatic clothing can be shielded (<200V), the static electricity generated through the floor and the grounding line of various parts of the plant to the outside of the general grounding wire.

一,The purpose of preventing static electricity

1, strengthen the consciousness of the workers on the anti static operation

2, reduce the poor production caused by static electricity

3, prevent static electricity from causing damage to the product

二,Scope of application: all SMT production lines

三,The reasons

The generation of static electricity is not perceived, but the static electricity produces the voltage of tens of thousands of volts. When the static electricity comes into the tip (the static release point, such as the human finger), it releases all the energy in a moment, causing the contact material to be struck by electric shock, causing the capacitance, IC, line road and so on to be destroyed and burned, so that the product is strict. In the case of heavy damage, static electricity measures should be taken. .

(一)Prevention and treatment of human static electricity

1, the workers should wear electrostatic clothing, work shoes;

2, the operator should take electrostatic gloves when working.

3, the operator should take an electrostatic ring in the operation.

(二)Prevention and control of static electricity

  1. Make use of electrostatic materials to produce production tools.

2, the storage place to prevent static electricity;

(三)Prevention and control of static electricity of a worktable / mobile vehicle

1, the anti static film should be pasted on the work table.

2, the operation platform / mobile vehicle must have antistatic grounding chain.Prevention of equipment static electricity: good grounding wire

(四)Prevention and control of material static electricity

  1. When the material is taken, the operator should use the antistatic method: with electrostatic gloves and electrostatic rings.

2, the material storage should be anti static measures: material cabinet to paste electrostatic film, grounding chain.

3, there should be anti-static measures in temporary storage area: installing grounding chain.

(五)Prevention and control of static electricity related to production: anti static measures should be taken when using items related to production: static wires and antistatic films.

 

五, Note:

  1. The online operators should strictly abide by this rule
  2. The online operators are supervised by the team leader, and the engineers are supervised by the engineers.
