In this century 70 before before era, do not have ESD consciousness as a result of people and very much electrostatic problem is created, although there also is very much person now,distrustful ESD is met cause damage to electronic product. Because most ESD damages the feeling that produces in the person,this is the following, because human body is opposite,the perceptive voltage of electrostatic discharge is 3 KV about, and a lot of electron component are in hundreds of bend over can damage when a few bend over even, there is apparent end after normally electronic parts is damaged by ESD, detect component installation again later on PCB, the result appears a lot of problems, the analysis is quite difficult also. Damage potentially especially, although use accurate instrument to measure its function very hard also to have apparent change, so very electronic engineer and design personnel suspect ESD, but in recent years the experiment confirms, this kind of potential damage is after proper time, the dependability of electronic product drops apparently.
2. Who should attend ESD to groom?
Groom who? Management grooms branch, the support of management department, automation line management grooms, worker, technician should get antistatic knowledge grooms. Newest American state level and international are electrostatic discharge association standard (ANSI/ESD S20.20-1999) electrostatic groom plan and groom requirement and attestation list technically. Electrostatic groomed key is getting administrator of tracheal manage personnel, automation line and project technology 3 kinds of people, but content and requirement each are not identical. To leader and administrator, outside knowing electrostatic safety to run a requirement except the requirement, right electrostatic and basic knowledge, antistatic electrostatic and the requirement of working area, subtle sign also should understand somewhat. And wait to personnel of technology of engineer of stylist, spot, maintenance right electrostatic be about to have comprehensive knowledge. Current, our country of all kinds school has electrostatic major except a few major outside graduate student course, technical secondary school, three-year institution of higher learning and undergraduate course all did not offer electrostatic special training course, introduced to concern electrostatic fundamental in the electricity that is physics only a few knowledge. But should have this base only, you can learn from good examples electrostatic defend basic knowledge.

3. Electrostatic damage to electronic product what form is there?
Electrostatic elementary physics character is: Attract or repel, have voltage with the earth, can produce discharge electricity. These 3 kinds of character can be right 3 kinds of influences of electronic component:
1. Electrostatic and adsorptive dirt, reduce component insulation resistance (shorten life) .
2. Electrostatic discharge is destroyed, make component damage cannot work (destroy) completely.
