Исследование функциональной характеристики проволочных потенциометров методом растровой электронной микроскопии

Abstract

Background. The research object is a resistive element of a wire potentiometer. The aim of the work is to determine functional characteristics of the resistive element, followed by simulation of its rejection under the influence of various factors. Materials and methods. The study was conducted using a specially developed technique for scanning electron microscopes, followed by treatment of the resulting image in the "Compass-3D». Next, using the program "Compass-3D», the author simulated the influence of eccentricity of the axis on potentiometer’s functional characteristics. Results. The author has developed the technique of controlling the functional characteristics of the resistive element (potentiometer) by scanning electron microscopy with the program "Compass-3D». Conclusions. Introduction of an intermediate step of potentiometer’s resistive element control into the technological process according to the proposed method will allow to discard resistive elements with functional characteristics inconsistent with technical requirements at the initial stage, to reduce the percentage of defective items, to check the build quality of potentiometers and to reduce production costs.

Актуальность и цели. Объектом исследования является резистивный элемент проволочного потенциометра. Цель работы определение функциональной характеристики резистивного элемента с последующим моделированием ее отклонения под воздействием различных факторов. Материалы и методы. Исследование проводилось по специально разработанной методике для растрового электронного микроскопа с последующей обработкой полученного изображения в программе «Компас-3D». Далее при помощи программы «Компас-3D» проводилось моделирование влияния эксцентриситета оси на функциональную характеристику потенциометра. Результаты. Разработана методика контроля функциональной характеристики резистивного элемента (потенциометра) методом растровой электронной микроскопии с применением программы «Компас-3D». Выводы. Внедрение в техпроцесс промежуточного этапа контроля резистивного элемента потенциометра по предложенной методике позволит на начальной стадии отбраковать резистивные элементы с несоответствующей техническим требованиям функциональной характеристикой, снизить процент бракованных изделий, проконтролировать качество сборки потенциометров и сократить затраты на производство.
