Antistatic Vinyl Gloves Technology Development
Jun 21, 2017

Static electricity is a kind of electric energy, Antistatic Vinyl Gloves it remains on the surface of the object, is the positive and negative charge in the local range of the result of loss of balance, is formed by the conversion of electrons or ions. The electrostatic phenomenon is the general term for the electrical phenomena that occur during the generation and disappearance of the charge. Such as friction from the power, the body electrification and other phenomena.

With the development of science and technology, Antistatic Vinyl Gloves electrostatic phenomena have been widely used in electrostatic spraying, electrostatic weaving, electrostatic sorting, electrostatic imaging and other fields. On the other hand, the generation of static electricity in many areas will bring significant harm and loss. For example, in the first Apollo manned spacecraft, Antistatic Vinyl Gloves three astronauts were killed by electrostatic discharge, and in the case of an electric discharge (ESD) in the manufacture of gunpowder. In the electronics industry, with the increasing integration, the integrated circuit of the inner insulation layer is getting thinner, the interconnecting wire width and spacing are getting smaller and smaller, for example, CMOS device insulation layer typical thickness of about 0.1μm, Its corresponding breakdown voltage in the 80-100V; VMOS device insulation thinner, breakdown voltage at 30V. And in the manufacture of electronic products and transportation, storage and other processes generated by the electrostatic voltage far more than the MOS device breakdown voltage, Antistatic Vinyl Gloves often the device will produce a hard breakdown or soft breakdown (device local damage) phenomenon, so that failure Or seriously affect the reliability of the product.

In order to control and eliminate ESD, the United States, Western Europe and Japan and other developed countries have developed national, military and corporate standards or regulations. From the electrostatic sensitive components of the design, manufacture, purchase, storage, inspection, storage, assembly, commissioning, semi-finished and finished product packaging, transportation, etc. Antistatic Vinyl Gloves have the corresponding provisions of the electrostatic protection equipment manufacturing use and management also has more stringent regulations System requirements. China has also developed military and enterprise standards in the light of international standards. For example, there are space, the Ministry of Electrical and Mechanical, Ministry of oil and other standards.

Electrostatic sensitive devices are known as electrostatic sensitive components (SSDs). Electrostatic sensitive devices mainly refer to ultra-large scale integrated circuits, especially metallized film semiconductors (MOS circuits). Table 1 is the classification of static-sensitive devices.Antistatic Vinyl Gloves According to the SSD rating table, for different SSD devices, take different electrostatic protection measures.

(1) the activities of the human body, people and clothes, shoes, socks and other objects between the friction, contact and separation of electricity generated by electronic products is one of the main electrostatic source. Human body static electricity is the main cause of the device to produce hard (soft) breakdown. Human activities produce an electrostatic voltage of about 0.5-2KV. In addition, the air humidity has a great influence on the electrostatic voltage, and if it is up to an order of magnitude in a dry environment.

(2) chemical fiber or cotton work clothes and workmans, chair friction, the clothing surface can produce more than 6000V electrostatic voltage, and make the body live, Antistatic Vinyl Gloves then contact with the device, it will lead to discharge, easy to damage the device.

(3) rubber or plastic soles of the insulation resistance up to 1013Ω, when the friction with the ground when the static electricity, and the body charged.

(4) resin, paint film, plastic film packaging device in the packaging of transport, the device surface and packaging material friction can produce a few hundred volts of electrostatic voltage, the discharge of sensitive devices.

(5) Various packaging, cartridges, and turnover of PP (Polypropylene), PE (Polyethylene), PS (Polystyrene), PVR (Polyurethane), PVC and Polyester, Antistatic Vinyl Gloves Resin and other polymer materials Box, PCB frame, etc. may be due to friction, the impact of 1-3.5KV static voltage generated, the sensitive parts of the discharge.

(6) ordinary work surface, by friction generated static electricity.

(7) concrete, wax polishing floor, rubber plate and other insulation on the ground insulation resistance is high, the human body electrostatic charge is not easy to leak.

(8) electronic production equipment and tools: such as electric iron, wave soldering machine, reflow furnace, placement machine, Antistatic Vinyl Gloves commissioning and testing equipment within the high-voltage transformers, cross / blind flow circuit will be induced in the equipment, static electricity. If the equipment electrostatic discharge measures are not good, will cause the sensitive device in the manufacturing process failure. The hot air circulation in the oven is rubbed against the cabinet, and CO2 vapor in the CO2 cooler tank can produce a large amount of static charge.
