QUALITY MANAGEMENT OF QUARTZ RESONATORS

Abstract

The formation of various devices of radio electronics and communication technology in general is associated with an increase in its reliability, the stability of the generated frequencies, and the selectivity of the receiving equipment. The problem of increasing the reliability of communication has been partially solved with the help of quartz resonators, which are widely used in radio circuits. The use of quartz resonators in electric generators allows to guarantee high frequency stability without complicating the circuit. The world trend in the development of modern electrical equipment is associated with miniaturization, quartz resonators in their dimensions are decreasing every year. At the same time, the requirements for reliability characteristics remain high. The purpose of this work is to evaluate the possibility of using quartz resonators presented in a miniature ceramic package with dimensions of 2.5×2.0×0.6 mm, in conditions with increased requirements for ambient temperature, as well as to select the most optimal requirements for thermal training mode, which is the basic technological operation for stabilizing the vibration frequency. Testing quartz resonators for reliability and methods of statistical modeling in radio engineering. Requirements for the reliability characteristics of quartz resonators RK588 in miniature ceramic cases 2.5×2.0×0.6 mm in size when exposed to an elevated ambient temperature of +85 C and +125 C. Requirements for frequency when exposed to increased ambient temperature on the type of crystal plate, created on the basis of RF patent No. 27122426 “Method for the manufacture of thin crystal plates and thin crystal elements”. The method of thermal training has been optimized and the aging coefficients have been established.
