Electrostatic damage on electronic products

Electrostatic damage on electronic products may take many forms and have their own characteristics. 

1 in the form of static electricity damage 

Electrostatic the fundamental physical properties are: to attract or exclusion, and the earth there is potential difference, will have a discharge current. These three characteristics of electronic components to three: 
(a) electrostatic dust absorption and lower component insulation resistance (to shorten the life span). 
(b) electrostatic discharge (ESD) damage to caused by electronic. 
(c) electrostatic discharge electromagnetic fields generated by a large margin (up to several hundred volts / meter) very wide spectrum (from a few dozen to several trillion Gigabit), the production of electronic devices and even damage caused by interference (EMI) 
These three components in the form of damage, both may be permanent (such as loss of function, can not be restored), or it may be temporary (such as electrostatic discharge so that the interference generated by the temporary loss of function); can be a sudden Failure, or it may be a potential failure. One electrostatic discharge (ESD) damage was caused by the most common components and the main reason. 

2 electrostatic damage characteristics 

Relative to other stress, static electricity damage to the electronics of the following features: 

(1) hiding 
The human body can not occur unless the perception of electrostatic discharge static electricity, but the occurrence of electrostatic discharge the human body may not be able to have a sense of shock, because the human perception of the ESD voltage of 2-3 KV, with static it hidden. 
(2) and the potential cumulative 
Some electronic components by static electricity damage after the performance did not decline significantly, but the cumulative number of discharge device will cause the formation of risk and internal injuries. Therefore, static electricity damage to the device has potential. 
(3) random 
The circumstances under which electronic components will be subjected to static electricity damage it? It can be said that arise from a component, it has been damaged, all in the process have been the threat of static electricity, which also has a static electricity generated with the mobility of. Damage to their sexual maneuverability also with. 
(4) the complexity of 
ESD damage of failure analysis, electronic products as a result of the fine, fine, the tiny structure and time-consuming, cumbersome, costly, require high technology and often require the use of scanning electron microscopy and other precision instruments. Even so, some of the phenomenon of static electricity damage will be difficult with the other causes of injury makes a distinction between people mistakenly static electricity damage as a failure of other failures. In this electrostatic discharge damage is not fully aware of before, often attributed to early failure or failure of unknown circumstances, and thus unconsciously cover up the real cause of the failure. Therefore, electrostatic damage on electronic devices with the complexity of the analysis. 

3, static electricity may damage the manufacturing process 

Components from production to use the process as a whole are at risk of electrostatic damage, according to the various stages of can be divided into: 
(1) components in the manufacturing process, including manufacturing, cutting, wiring, for delivery to the test. 
(2) of printed circuit board production process of receiving, inspection, storage, insert, welding, quality control, packaging and shipping to. 
(3) circuit board manufacturing equipment, inspection, storage, assembly, quality control and shipping. 
(4) the use of the process of receiving equipment, installation, testing, use and maintenance. 
(5) equipment maintenance 

In this whole process, every stage of each small step, all components may be subject to static electricity, in fact, the most important and easy to negligence on the part of that is in the components of the transmission and transport. In this whole process, not only because of packaging mobile prone to static electricity, but the whole package easily exposed to external electric field (for example, after a near high-voltage equipment, mobile workers, frequent, fast moving vehicles, etc.) have been damaged during transport and send it in need of special Attention in order to reduce losses and avoid the unnecessary disputes. 
Therefore, from the components in the manufacture, use and maintenance of any of the links can happen electrostatic damage.
