Beware of electrostatic hazards
We have the experience of being hit by static electricity when we comb our hair everyday, and we can also be electrified when we pull the door to open the door ... The degree of static electricity release is uncertain, just like a killer hidden in the depths! what? Say I exaggerate? Have you seen an article entitled: "A hair strand burned my book"? That is the masterpiece of static electricity!
Items are more or less charged with static electricity, and our human body is no exception. When static electricity meets a charged DD, there is no strict definition here. It is not necessarily DC and AC, and it is more likely that static electricity encounters static electricity! They will have an "electrostatic discharge" phenomenon. At this time, no one can be sure of the power of the charged particles. We should be extremely careful when using books! The integrated circuit in this book is abnormally sensitive to electrostatic discharge. That is because the strong high voltage released by static electricity is likely to break the oxide film inside the integrated circuit, and it is more likely to have a "locking effect" on the internal circuit of the book. "This situation is caused by a sudden surge in current, which causes the internal logic to fail. If the above situation occurs for a long time, the circuit will be severely burnt, and the consequences are unthinkable!
In order to prevent static electricity damage, the manufacturers have strict electrostatic protection for delicate CPUs, graphics cards, etc., and they wrapped the product in an anti-static packaging bag. If we need to open the case for repair and replacement, it is best to use a protective bag. Before opening the case, put your hands on other metal surfaces for a while to release the static electricity brought by your body, and then try to touch it a few times. If the metal inside the case can obviously feel the current passing through the hand, you should do the grounding operation in time! So that the human body itself and the book "battered and lost"! Oh, remember to read the report that there was an incident where static electricity burned down the factory building during a thunderstorm. Static electricity, this bad guy, can't be overlooked. Static electricity is a natural phenomenon. We can't eliminate it, but we can avoid it. As long as you are careful, accidents won't happen! So, for static electricity, you have to look at it as a big deal!
