Investigation of the dependence of the quality control of the adhesive joint on the capacitance of the joint for various types of dielectric

Abstract

The control of adhesive joints is a mandatory step in the process. However, at present, there is no device that could be used at various stages of production. The main part of the devices allows you to control finished products. The developed method is based on the use of measuring the electrical parameters of a compound to control the quality of this compound. The essence of the method is as follows. An article containing glued elements measures one of the electrical parameters: capacity or resistance. The obtained value is compared with the theoretical value of this parameter calculated and set as “tolerance”. If the measured value is within the tolerance, then a conclusion is drawn about the suitability of this adhesive joint; otherwise, the connection is rejected. The data obtained allow us to conclude that there is a relationship between the measurement of the capacitance parameter of the compound and the thickness of the dielectric layer. However, for it is necessary to study in depth how this method behaves when working with other dielectrics and a relationship is traced between them. The processing of resistance measurement data also shows that the use of data on this parameter is possible, but with stabilization of the measurement conditions, since a stronger discrepancy with the theoretical (calculated) values was observed during the measurement.

Measurement Assurance of Additive Manufacturing on the Example of Laser Surface Polishing Products by Remelting

“…The existing limitations in the measurement and control of parts manufactured using additive technologies require a wider introduction of non-contact measuring systems, including video measuring machines, laser micrometers, machine vision systems, 3D scanners, laser rangefinders and trackers, triangulation sensors, etc. [17,18,19].…”
