Why should electronic factory should use ESD products?
The electrostatic current is generally small, but the potential difference is very large, and there may be phenomena such as attraction, repulsion, conduction, and discharge.
1 adverse effects on screen printing. The screen at the time of printing heats the rubber portion and the screen due to the pressure scraping of the blade rubber. When the screen itself is charged, it will affect the normal inking and cause the jamming failure; it will be sucked by the screen at the moment of the output of the substrate.
a. The glass is easily charged when the heating wire is printed.
b. Static electricity tends to cause the glass surface to adsorb ink particles, making the glass surface unclean.
c. Human body electric shock caused by static electricity is caused by contact with live objects or spark discharge caused by static electricity before grounding. Although the current generated by the electric shock is small, there is no danger, but electric shock often occurs, which will adversely affect the psychology of the operator.
2 Method to prevent static electricity. The methods for preventing static electricity generation include: adjusting the ambient temperature and increasing the air humidity. The appropriate temperature is generally about 20 ° C, and the relative humidity is about 60%; the static electricity can be transmitted in the wet air; the mesh distance is reduced, and the printing speed is reduced.
Electronic products should be anti-static:
Because most of the electronic products have circuit boards, and there are components such as capacitor diodes on the power board, they generally allow the current to pass through very small. If the static electricity of the human body is more, it will be generated after the electricity on the circuit board is followed. The current can be damaged by the breakdown of the components, so the general electronics factory should wear anti-static clothing and wear insulated gloves.
Static electricity is a charge that is at rest. In dry and windy autumn, people often encounter this phenomenon in daily life: when they undress and sleep at night, they often hear the sound of snoring in the dark, accompanied by blue light. When they meet hands, they just touch the finger. The other party will suddenly feel the tingling of the fingertips, which is very shocking. When you comb your hair in the morning, the hair will often “float”. The more you mess, the more you will pull the door handle and the faucet will “electric shock”, often issued The sound of "啪, 啪, 啪", this is the static electricity that occurs in the human body.
Because most of the electronic products have circuit boards, and there are components such as capacitor diodes on the power board, they generally allow the current to pass through very small. If the static electricity of the human body is more, it will be generated after the electricity on the circuit board is followed. The current can be damaged by the breakdown of the components, so the general electronics factory should wear anti-static clothing and wear insulated gloves!
