Problems solved by technology

Its method of detecting whether the operator has worn the electrostatic ring is: within 3 minutes before going to work, the team leader arranges each operator to measure the impedance worn by the electrostatic ring within 800KΩ to 9MΩ to judge whether it is good or not. However, if one of the operators has not worn the electrostatic ring within a certain period of time during work, everyone will not know

Embodiment Construction

[0018] As shown in Figure 2, the static automatic instant warning device 9 of the present invention is used to detect the use status of a plurality of electrostatic collection elements RESL, and it includes: a plurality of static instant detectors 1, which are used to generate status signals; one or Logic circuit 3, produces total status signal when at least one static instant detector above receives abnormal status signal; Timely drive total warning device 5 sends alarm sound and light information.

[0019] Suppose a production line has a total of n operators, counting from left to right, operator 1, operator 2, operator 3, operator 4... until operator n, each operator is for electrostatic discharge protection during production (electrical static discharge protection) To prevent the static electricity from the operator's body from damaging products during production operations (such as integrated circuits, motherboards, drawing boards, sound cards, etc.), it is necessary to w...

Abstract

The device consists of multiple immediate static electricity detector, an OR-logic circuit and a general actuator as immediate static electricity detector is equipped with a RC-oscillator, pulse width regulation controller, voltage comparator, driving amplifier and personal warner. The automatic immediate static electricity warning device can check out at any time whether static electricity collection component is accessorized on operator at each production line or not and it can launch alarm in both modes of sound and light if it finds that something is wrong.

Description

(1) Technical field [0001] The invention relates to an automatic static warning device, a real-time static detector and a static static real-time warning method for detecting the use status of a plurality of static collection components. (2) Background technology [0002] Electrostatic grounding engineering is widely used in integrated circuit manufacturing and precision circuit assembly workplaces, especially for static-sensitive integrated circuits and some electronic circuits, it is necessary to implement electrostatic grounding engineering to remove the static electricity from the human body of factory workers Static electricity is completely introduced into the earth. Therefore, in the production, manufacturing, testing, packaging, assembly and other links of semiconductor components, there are unified settings for electrostatic protection. [0003] FIG. 1 illustrates a circuit block diagram of an existing ESD protection system. Its method of detecting whether the ope...
