Embodiment Construction

[0062] The present invention will be further elaborated below through specific embodiments in conjunction with the accompanying drawings.

[0063] figure 1 It is a process schematic diagram of a parylene film that is easily peeled off from the substrate deposited on the surface of an electrical and electronic system. Taking the low surface energy hydrophobic material silane as an example, the preparation process of the parylene film that is easy to peel off from the substrate and is suitable for complex and closed electrical and electronic system internal discharge event detection in the present invention is as follows:

[0064] figure 1 In (a), silane is deposited on the surface of the electrical and electronic system O using chemical vapor deposition technology. Due to the hydrolysis and polycondensation of silane, a super-hydrophobic layer 2 (30-60 microns in thickness) can be formed on the surface of the device.

[0065] figure 1 (b) After the silane super-hydrophobic ...

Abstract

The invention discloses a discharge detection system and method based on a poly-p-xylylene film and charged particles. Based on a film deposition technology, a poly-p-xylylene film is deposited in a complex, closed and micro electrical and electronic system and on the surface of an electrical and electronic system in an embedded manner; the micron-sized poly-p-xylylene film is conformal with an electrical and electronic system, so that large-area, all-around and dead-angle-free coverage in the electrical and electronic system is realized; based on a poly-p-xylylene film polarity technology andin combination with the electrostatic interaction of charged particles, discharge detection of the whole electrical and electronic system, precise discharge positioning of the electrical and electronic system in the system and calculation of discharge key parameters are realized; according to the invention, the universality of the discharge detection technology is improved, and the problem that the existing discharge detection technology cannot realize the detection and accurate positioning of the internal discharge of a complex, closed and micro system is solved; the effectiveness and the precision of the discharge detection technology are improved; and the robustness of the discharge detection technology for resisting the interference of the internal environment of the system is improved.

Description

technical field [0001] The invention relates to a discharge positioning and detection technology, in particular to a detection system and method for an internal discharge event in an electrical and electronic system based on the electrostatic interaction between a parylene film and charged particles. Background technique [0002] Electrical and electronic systems in the national defense industry face the threat of discharge phenomena such as lightning discharge, medium electrostatic charge accumulation discharge, and instantaneous high-voltage pulse discharge in complex electromagnetic environments. Once a discharge event occurs in a weak component in the system, the instantaneous large current pulse will cause the failure of the entire electrical and electronic system. The detection technology of discharge events is a key means to obtain discharge parameters such as discharge location, discharge voltage, duration, and discharge energy. It is extremely important for analyzin...
