Abstract

The invention discloses an electrostatic detection device, which is suitable for detecting objects to be tested. The electrostatic detection device includes a carrier plate, a sensing electrode, a dielectric film layer and a grounding electrode. The carrier board has a first surface and a second surface opposite to the first surface. The sensing electrode is arranged on the first surface and has a sensing surface. The sensing surface faces away from the first surface and is used to face the object to be measured. The dielectric film layer is disposed on the second surface and the dielectric constant of the dielectric film layer is greater than 1. The ground electrode and the sensing electrode are spaced apart, and the dielectric film layer is located between the sensing electrode and the ground electrode.

Description

technical field [0001] The invention relates to an electrostatic detection device, in particular to an electrostatic detection device with a high dielectric constant dielectric film layer. Background technique [0002] With the development of technology and market demand, the design trends of electronic products such as smart phones and tablets are all towards light, thin, short, small and multi-functional development. However, this makes the electronic components / components assembled in the module more expensive In the precise and miniaturized manufacturing process, sudden electrostatic interference is often encountered, which will lead to the breakdown and damage of the component or module structure and functional failure, further affecting the production yield and product quality. [0003] Furthermore, most of the existing electrostatic sensors are hand-held or fixed-point measurement, which cannot meet the real-time monitoring requirements. In addition, the electrostati...
