Electronics

It is the invisible enemy of electronic products

Over the past half century, accidents such as fires and explosions caused by static electricity in the electronic industry are countless. The electronic industry in the United States alone incurs tens of billions of dollars in annual losses due to static electricity. Therefore, electrostatic protection is of great significance in reducing losses, improving quality, and improving consumption efficiency.
With the rapid development of the integrated circuit industry, devices with small size and high integration are becoming increasingly popular in the market. This demand has also led to smaller and smaller spacing between wires, and the internal oxide film gradually becoming thinner, so that some small voltages during the manufacturing process may break down these electronic devices. However, the electrostatic voltage generated by electronic products during a series of processes such as production, transportation, storage, and transportation far exceeds their withstand voltage value, which may cause breakdown or failure of devices, affecting the reliability of the product. Therefore, attention must be paid to electrostatic protection to fundamentally solve this problem.
Causes of static electricity
Electrostatic electricity is a natural phenomenon. Generally speaking, there are three main sources of electrostatic generation: friction, induction, and conduction. In the manufacturing process of electronic products, static electricity can be generated in multiple processes such as welding, assembly, testing, and packaging. The generation of static electricity on the one hand lies in the characteristics of electronic components themselves, on the other hand, it also has an important relationship with production and operating personnel. If production personnel do not operate in accordance with anti-static regulations, electrostatic protection measures are not fully worn, and conductive objects are placed disorderly during the production process, static electricity may be generated. Because electronic devices are mostly conductive materials, static electricity may be generated under the action of an electrostatic field during the contact process of the device.
Measures for electrostatic protection
The harm of static electricity is obvious to all, and now many manufacturers in the electronic industry have begun to implement various electrostatic protection measures. However, it should be recognized that improving and effective electrostatic protection requires formulating corresponding countermeasures according to different situations of different enterprises. Electrostatic protection measures should be systematic and comprehensive, otherwise they may cause destructive reactions. Here are some protective measures for the electronic industry:
·Wear anti-static clothing, pants, shoes, and other anti-static items.
·Some workbenches, test instruments, and other electrical equipment should be grounded.
·Strictly control the humidity and temperature of the production environment.
·Install an ion fan to neutralize the static electricity generated by PCB and components due to high temperature hot air.
Electrostatic electricity is everywhere, so taking good electrostatic protection measures is equivalent to eliminating a major safety hazard for the production of electronic products. With the rapid development of the current electronic industry, electrostatic protection technology also needs to be continuously improved and developed.
