Description

A kind of fire-resistant antistatic aluminum foil bag

Technical field

The utility model is specifically related to a kind of fire-resistant antistatic aluminum foil bag.

Background technology

At present, the application of electronic product gets more and more, owing to the precise structure of electronic devices and components is complicated, in the process circulated and use, easily it is subject to the infringement of electrostatic and water vapour molecule, the lighter makes the electrical parameter of electronic component drift about, life-span shortens, severe one makes components and parts complete failure, the circuit of ic component reduces, withstand voltage reduction, circuit area reduces, make the device reduced capability of resistance to electrostatic impact, static electric field and electrostatic electric current become the fatal killer of these high-density components and parts, the generally application of the contour insulating material of simultaneously a large amount of plastics, the chance producing electrostatic is caused to increase, as walked about in daily life, air flow, carrying etc. can produce electrostatic, people it is generally acknowledged that the chip of only CMOS class can to electrostatic sensitive, in fact, the component circuit that integrated level is high is all very responsive.

Electrostatic is on the impact of electronic package:

1. electrostatic adhesion dust, changes the impedance of line member, affects function and the life-span of product;

2., because electric field or electric current destroy insulation or the conductor of assembly, assembly can not be worked;

3., because of the heat that electric field or the electric current of moment produce, assembly is injured, still can work, and the life-span is impaired.

The feature of electrostatic damage:

1. disguised, human body can not direct perception electrostatic, unless there is static discharge, but generation static discharge, human body also differs the sensation of electric shock surely, this is because the static discharge voltage of human perception is 2-3KV;

2. latent, after some electronic devices and components receives electrostatic damage, performance does not significantly decrease, but repeatedly cumulative electric discharge can cause internal injury to device and form hidden danger, and adds device to the susceptibility of electrostatic, and the problem produced there is no any method and can solve;

3. randomness, electronic package can be subjected to electrostatic breakdown in what situations, so to say that, after producing from an assembly before he damages, all processes all can receive the threat of electrostatic, and the generation of these electrostatic also has randomness, owing to generation and the electric discharge of electrostatic occurs all instantaneously, and difficulty is predicted and protection;

4. complicacy, static discharge damage point plate work, meticulous because of electronic product, tiny constructional feature and time-consuming, bothersome, expensive, require that more complicated technology often needs to use the precision instruments such as scanning electron microscope, even so the damage that some electrostatic damage phenomenon is also difficult to cause with other reasons is distinguished, people was lost efficacy electrostatic damage by mistake lost efficacy as other, this be damage of electrostatic discharge is not fully realized before, usually it is attributed to getting up early inefficacy or inefficacy in confused situation, thus the unconscious true cause masking inefficacy.

For the problems referred to above, occur by anti-static shielding bag, this film comprises body layer, is fixedly connected on the skin of the anti-electrostatic outside body layer and is fixedly connected on the anti-electrostatic internal layer inside body layer, body layer wherein is generally two layers of composite structure, one layer, outside is polyester metal level, the second layer is PE polyethylene layer, due to the existence of inside and outside antistatic backing, this packing bag can prevent the infringement of electrostatic effectively, the function with anti-electrostatic, but also there is very big defect in other performances of anti-electrostatic bag that above-mentioned electrostatic prevention film is made.
