Electrostatic detection devices and methods thereof

Abstract

An electrostatic detection device, which is configured to detect an electrostatically sensitive area of an electronic device causing a specific event to happen to an electronic device, includes an electrostatic metal plate, a detector, and a controller. The electrostatic metal plate is configured to generate an electrical field and includes a first surface which is parallel to the electronic device. When the specific event is detected, the detector generates a detection signal. The controller moves the first surface relative to the electronic device and receives the detection signal. When thedetection signal is received, the controller determines that the electrostatically sensitive area is a first area of the electronic device overlapped with the first surface.

Description

technical field [0001] The invention relates to a device and method for detecting electrostatic sensitive areas of electronic devices. Background technique [0002] Today's electronic devices are becoming smaller and smaller as the size of the semiconductor process and users' requirements for portability make the printed circuit boards in electronic products smaller and smaller, and the electronic components on the printed circuit boards are denser. In addition, in order to meet more complex electronic functions, the high logic level and the ground level inside the integrated circuit will become closer, making it more difficult for electronic products to meet the specifications for the tolerance to static electricity. [0003] However, for engineers, the biggest difficulty in improving the tolerance of static electricity is how to find the area of ​​the system that is disturbed by static electricity, which will consume a lot of time in the search process. Therefore, there i...
