晶振是遥控器控制电路中最关键的零部件之一,起着举足轻重的作用,而晶振的过早失效是造成遥控器故障的主要原因之一。本文从遥控器的工作原理和晶振的工作原理、失效模式及失效分析出发,阐述遥控器晶振寿命筛选电路的设计,来进行晶振寿命筛选,达到对晶振质量的控制。
Crystal oscillator is one of the most critical parts of the remote control circuit, plays a decisive role, and the premature failure of the crystal oscillator is one of the main causes of remote control failure. In this paper, starting from the working principle of the remote control and working principle, failure mode and failure analysis of the crystal oscillator, the design of the crystal lifespan screening circuit of the remote control is expounded to screen the crystal life and achieve the control of the crystal quality.
