Description

Anti-static shielding aluminum foil bag

Technical field

The utility model is specifically related to a kind of anti-static shielding aluminum foil bag.

Background technology

At present, the application of electronic product is more and more, due to the precise structure complexity of electronic devices and components, in the process of circulation and use, easily be subject to the infringement of static and water vapour molecule, the lighter makes the electrical quantity drift of electronic component, the lost of life, severe one makes components and parts entirely ineffective, the circuit of ic component dwindles, withstand voltage reduction, circuit area reduces, the resistance to electrostatic impact ability of device is weakened, static electric field and electrostatic induced current become the fatal killer of these high density components and parts, the generally application of simultaneously a large amount of contour insulating materials of plastic products, cause the chance that produces static to increase, in daily life as walk about, Air Flow, carrying etc. can produce static, people it is generally acknowledged to only have the chip of CMOS class can be to electrostatic sensitive, in fact, the components and parts circuit that integrated level is high is all very sensitive.

The impact of static on electronic building brick:

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

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

3. the heat producing because of electric field or the electric current of moment, assembly is injured, endure, the life-span is impaired.

The feature of electrostatic damage:

1. disguise, human body is perception static directly, unless there is static discharge, but there is static discharge, human body also differs the sensation of electric shock surely, and this is because the static discharge voltage of human perception is 2-3KV;

2. latency, after some electronic devices and components is received electrostatic damage, performance does not significantly decrease, but repeatedly cumulative electric discharge meeting causes internal injury and forms hidden danger to device, and has increased the sensitiveness of device to static, and the problem having produced there is no any method and can solve;

3. randomness, electronic building brick can be subjected to electrostatic breakdown in what situations, so to say that, from an assembly is produced until before his damage, all processes all can be received the threat of static, and the generation of these static also has randomness, because generation and the electric discharge of static are all to occur moment, and difficult prediction and protection;

4. complexity, electrostatic discharge damage divides plate work, meticulous because of electronic product, tiny design feature and time-consuming, bothersome, expensive, require more complicated technology often to need to use the precision instruments such as ESEM, even so the damage that some electrostatic damage phenomenon is also difficult to cause with other reasons is distinguished, people's mistake was lost efficacy electrostatic damage as other inefficacies, this be damage of electrostatic discharge is not fully realized before, usually be attributed to getting up early and lost efficacy or inefficacy in confused situation, thus the automatic true cause losing efficacy of having covered.

For the problems referred to above, occur by anti-static shielding aluminum foil bag, this film comprises body layer, it is outer and be fixedly connected on the antistatic internal layer of body layer inner side to be fixedly connected on the antistatic in body layer outside, body layer is wherein generally two layers of composite construction, outside one deck is polyester metal level, the second layer is PE polyethylene layer, due to the existence of inside and outside antistatic backing, this packaging bag can prevent the infringement of static effectively, there is the function of antistatic, but also there is very large defect in other performances of the antistatic bag that above-mentioned electrostatic prevention film is made.

Utility model content

Utility model object: the problem and shortage existing for above-mentioned prior art, the purpose of this utility model is to provide a kind of anti-static shielding aluminum foil bag.

Technical scheme: the utility model discloses anti-static shielding aluminum foil bag, comprise bag, bag comprises base cloth and supporting layer, supporting layer comprises metal level and is wrapped in the fabric of layer on surface of metal, metal level is aluminum membranous layer, fabric and base cloth are made and are formed by antistatic woven cloth, and antistatic woven cloth is intersected and made by monofilament spandex and antistatic silk, and wherein monofilament spandex and antistatic silk quantity are than being 3:5.

As further optimization of the present utility model, base cloth described in the utility model is made up of the antistatic woven cloth of layer 2-3.

As further optimization of the present utility model, fabric described in the utility model is made up of the antistatic woven cloth of 1-2 layer.

As further optimization of the present utility model, the twist of spandex described in the utility model and antistatic silk is that 80-95 twists with the fingers.

As further optimization of the present utility model, base cloth described in the utility model is provided with politef coating.

Beneficial effect: the utility model compared with prior art, have the following advantages: the utlity model has good anti-static ability, effectively solve the electrostatic problem of product in depositing, transporting, adopt supporting layer simultaneously, there is good structural strength, long service life.
