Electro-static discharge device

Abstract

Disclosed is an electro-static discharge device, wherein an electro-static discharge channel is provided for an assembly station and accordingly the electro-static protection can be performed on electronic products. According to the electro-static discharge device, an operator wears an ESD (Electro-Static Discharge) wrist strap to be connected with the ground to ensure that a grounding resistor can be located within a range of 1* 10 <6> to 1 * 10 <7> ohms or other ranges and ensure that electro-static potentials of a human body of the operator are located within a specialized range and accordingly performance parameters of components cannot be damaged when the operator is in contact with the electronic components.

Description

technical field [0001] The invention relates to the field of static electricity, in particular to an antistatic device. Background technique [0002] With the advancement of science and technology, the integration of electronic products has increased rapidly, VLSI has been mass-produced and widely used, the size of devices has become smaller and the oxide film inside the chip has become thinner, which reduces the ability of components to withstand electrostatic discharge and becomes an electrostatic sensitive device. . In the assembly of electronic products, from the pretreatment of components, placement, welding, cleaning, testing and other processes, due to the effects of contact, separation, friction, collision, induction, etc., components, components, and products will be exposed to static electricity and produce ESD. , and the electrostatic discharge voltage that electrostatic sensitive devices in electronic product assembly can withstand is generally several hundred v...

Problems solved by technology

In the assembly of electronic products, from the pretreatment of components, placement, welding, cleaning, testing and other processes, due to the effects of contact, separation, friction, collision, induction, etc., components, components, and products will be exposed to static electricity and produce ESD. , and the electrostatic discharge voltage that electrostatic sensitive devices can withstand in the assembly of electronic products is generally several hundred volts, and the best is only a few kV. Electrostatic discharge will cause damage to components. It mainly manifests two types: one is to cause the entire The failure and damage of components is called hard breakdown; the other type is to cause slight damage to components and reduce the performance parameters of components, which is called soft breakdown; soft breakdown is more harmful than hard breakdown, because static electricity The damage of discharge to components occurs unconsciously. After being slightly damaged by static electricity, it cannot be found in the assembly inspection process, but it can only be developed into a device after the product is officially put into use for a period of time. complete failure, the consequences will be more serious
