The entire process of electronic components from production to use will generate static electricity, which can be divided into:
1. Electronic component manufacturing process
This process includes manufacturing, cutting, wiring, inspection to delivery.
2.Printed circuit board production process
Receiving, acceptance, storage, insertion, welding, quality control, packaging and shipment.
3. Equipment manufacturing process
Circuit board acceptance, storage, assembly, quality control, and shipment.
4. Equipment use process
Receiving, installation, testing, use and maintenance.
5. Equipment maintenance process
During this whole process, every small step in each stage, the component may be affected by static electricity. In fact, the most important and easily overlooked point is the process of component transmission and transportation. During this whole process, not only the package is prone to generate static electricity due to movement, but the entire package is easily exposed to external electric fields (such as passing near high-voltage equipment, frequent workers moving, vehicles moving rapidly, etc.), so the transportation and transportation process needs special Pay attention to reduce losses and avoid unnecessary disputes.
Therefore, electrostatic damage may occur at any stage from the manufacturing of electronic components to the use and maintenance.
The damage of static electricity to electronic products is similar to the damage of cancer to humans. It is no exaggeration to say that static electricity has become an invisible lethal killer of the electronics industry.
