With the rapid development of science and technology, microelectronics technology has been widely applied, electromagnetic environment and electrostatic discharge process of the damage of microelectronic components are widespread, especially electrostatic.
Therefore in the process of storage, transportation and use are to be protection, anti-static bags arises at the historic moment, become a solid shield of precision electronic components.
A, anti-static bags is a multi-layer compounded special plastic film and the metal film, anti-static, electromagnetic, anti interference, moisture-proof, waterproof, dustproof and shockproof function, such as its high strength, good toughness, strong rigidity, heat resistance, cold-resistant, etc, but also has good resistance to environmental stress cracking, tearing strength, such as performance, suitable for temperature, humidity and electromagnetic field requirement of the electronic product packaging.
Second, the material combination and function of 1.
Lining: lining material for static dissipative material, is refers to between conductor and insulation materials, is advantageous to the electrostatic discharge process does not harm the need to protect electrostatic sensitive electronic components.
Principle is the use of insulation materials, almost no discharge between the conductor will be done within a few decades nanoseconds discharge process, and the static dissipative material could be extended by electrostatic discharge rate, relatively slow release of electrostatic, so as to avoid the instant release a powerful current, breakdown of electronic products.
Middle tier: the middle layer is also called the shielding layer of aluminum foil material, aluminum foil has the very good barrier property, can effectively shield the dangers of electrostatic field of electronic products.
Outer layers: the outer protective layer, mainly to increase the strength of the packaging bags, wear resistance, avoid in the process of storage and transportation, due to the broken bag bag lost protection, causing great economic losses.
Three, other application anti-static bags not only applies to all kinds of PC boards, IC integrated circuit, optical drive, hard disk, electronic components, etc.
Also applicable to other precision machinery parts, consumer goods, industrial products such as anti-oxidation corrosion protection packaging.
