Abstract

An antistatic device for the electronic product assembly station provides a static electricity discharge passage for the assembly station in order to protect electronic products from static electricity. By grounding an ESD (electrostatic discharge) wristband worn by an operator and other ways, the ground resistance can be kept at 1 multiplied by 106 ohms to 1 multiplied by 107 ohms or in another range, so that the electrostatic potential of the body of the operator can be blow a specified range, and thereby the performance parameters of elements cannot be destroyed when the electronic elements are touched by the operator.

Description

A kind of anti-static device of electronic product assembly station

Technical field

The utility model relates to electrostatic art, particularly a kind of anti-static device of electronic product assembly station.

Background technology

Along with scientific and technological progress, the integrated rapid raising of electronic product, very lagre scale integrated circuit (VLSIC) is produced and extensive use in a large number, the diminishing and the oxide-film attenuation of chip internal of device size, the ability that makes components and parts bear static discharge descends and becomes electrostatic sensitivity device.In the electronic product assembling, from the preliminary treatment of components and parts, mount, weld, clean, operation such as test, because effects such as contact, separation, friction, collision, induction, the capital makes components and parts, assembly, product contact static and produce ESD, and the static discharge voltage that electrostatic sensitivity device can bear in the electronic product assembling is generally several hectovolts, best is also only counting kV, static discharge can cause the damage of components and parts, he mainly shows two classes: a class is to cause whole failure of elements and damage, claims hard breakdown; Another kind of is to cause slightly wounding of components and parts, reduces the performance parameter of components and parts, claims soft breakdown; Soft breakdown hazard ratio hard breakdown harm is bigger, because static discharge takes place under involuntary situation the damage of components and parts, after suffering that static slightly wounds, in the inspection process of assembling, can not be found but by the time product formally come into operation after a period of time, just can develop into the complete failure of device, its consequence will be more serious.And static is as a kind of natural phenomena, and it is impossible wanting thoroughly to disappear, and only takes to reduce the safeguard procedures of electrostatic hazard, reduces the loss of electrostatic hazard to greatest extent.

Summary of the invention

For achieving the above object, the utility model provides a kind of anti-static device of electronic product assembly station.

A kind of anti-static device of electronic product assembly station comprises that a workbench 3, place mat are at the ESD of work top mat 1 and the esd wrist strap 2 that is installed in the antistatic of workbench 3 one sides; Eliminate static by the mode of operating personnel being worn the direct earth connections of metal object such as esd wrist strap 2 ground connection, work top place mat ESD mat 1 ground connection and machine, workbench.

Operating personnel wear esd wrist strap 2 and comprise base band 2.4, earth electrode 2.5, are positioned at upper fastener on the earth electrode, are positioned at the following fastener 2.2 on the base band 2.4, are provided with spring 2.3 between upper fastener 2.1 and the following fastener 2.2; ESD mat 1 is two-layer structure, and superficial layer is the electrostatic dissipation layer, and bottom is conductive layer.

Described upper fastener 2.1, following fastener 2.2 and spring 2.3 all adopt metal material.

Described ESD mat 1 material is made by conducting electrostatic materials, static dissipative material and tartan.

The utility model takes to reduce the safeguard procedures of electrostatic hazard, reduces the loss of electrostatic hazard to greatest extent.

Description of drawings

Accompanying drawing is structural representation of the present utility model.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

With reference to accompanying drawing, a kind of anti-static device of electronic product assembly station comprises that a workbench 3, place mat are at the ESD of work top mat 1 and the esd wrist strap 2 that is installed in the antistatic of workbench 3 one sides; Eliminate static by the mode of operating personnel being worn the direct earth connections of metal object such as esd wrist strap 2 ground connection, work top place mat ESD mat 1 ground connection and machine, workbench.

Operation principle of the present utility model is:

Be lined with ESD mat 1 on operation element table top upper berth, operating personnel wear esd wrist strap 2 and metal objects such as machine, workbench 3 are eliminated static in the mode of direct earth connection; in 1s with electrostatic leakage; voltage is down to below the 100V; satisfy the assembling contact requirement of electronic devices and components, farthest protect electronic devices and components.
