I do n’t know, a little static electricity is harmful to electronic components such as terminals

It is often triggered in daily life, but everyone may not know that this little static electricity can actually cause harm to electronic components such as terminals.

In industrial production, the friction between the clothing and the body on our bodies, the friction between people, and the friction between people and machines are prone to static electricity, which is very slight.

For electronic components such as high-precision terminal blocks, the distance between the components is small and the sensitivity is high, causing them to be more easily damaged when they exceed their normal operating voltage or current. In addition, in the same integrated package of components, One component is damaged,

When the maintenance cost is higher than the replacement cost, more companies choose to replace it.

Suppo editors think many people will say that a capacitor itself can hold a lot of charge. Why is there electrostatic damage that causes breakdown? Because static electricity itself has a high potential difference or high voltage.

And this kind of static electricity will form a high voltage breakdown capacitor when it is discharged to the capacitor, because the capacitor itself can withstand a relatively small voltage, so it is easy to be broken down.

The editor also learned from the online information that static electricity not only causes damage to components such as terminals and circuit boards, but another kind of damage is that high-voltage static electricity generates electrostatic fields, attracts dust and other substances. After these substances absorb moisture in the air The formation of electrical conduction causes a short circuit of the circuit board.

So as a consumer, how can we prevent static electricity? According to the principle of electrostatic discharge-a large amount of charge is accumulated.

We can clear the static electricity during the production process, such as adding an anti-static grounding net, wearing an anti-static wrist strap when the human body touches terminals and other components, and connecting it to the anti-static grounding net. Its function is to pass the static electricity on the human body through these The device is quickly released into the ground, reducing the electrostatic charge carried, so that the static electricity cannot form a discharge condition, and reducing the harm of static electricity to components such as terminal blocks.
