Abstract

The invention relates to the technical field of mounting seats. The SMT circuit board electric measurement device based on the capacitance principle comprises a frame, a rotating disc is movably connected to a right arm of the frame, a metal part is fixedly connected to the inner side of the rotating disc, a spherical key is movably connected to the inner bottom wall of the frame, an actuating rodis movably connected to the lower end of the spherical key, and a combination disc is movably connected to the lower end of the actuating rod. The SMT circuit board electric measurement device basedon the capacitance principle is provided, suckers are tightly adsorbed on the frame; when the suckers are adsorbed on the frame, equipment is electrified to drive a dielectric block to vibrate, the dielectric medium moves in an electric field formed by electrode plates; the change of the electric quantity can be changed along with the increase or decrease of the area, corresponding to the electrode plates, of the dielectric block, and whether a specified qualified detection value is reached or not is checked according to the change of mechanical vibration and current of an electronic componentin cooperation with an electric measuring instrument such that the effect of convenient measurement is achieved.

Description

technical field [0001] The invention relates to the technical field of mounting seats, in particular to an electrical measurement device for SMT circuit boards based on the principle of capacitance. Background technique [0002] SMT refers to the abbreviation of a series of process processes processed on the basis of PCB. It is a printed circuit board. SMT belongs to surface assembly technology, also called surface mount technology. It is the most popular technology and process in the electronic assembly industry. , The mounting seat is mainly composed of welding plates, via holes, mounting holes, wires, components, and connectors. The circuit board is also called a flexible mounting seat and a soft-hard combination board. [0003] The traditional vibration detection has low accuracy in monitoring the operating state of the equipment structure and fault diagnosis. The electric measurement method is to convert the vibration of the measured object into electric quantity, and t...
