未通电状态下电路板上电容测试方法的分析

Analysis of the Methhod of Testing Capacitors on Unpowered PCB

本文对影响电路板上电容测试精度与范围的几种因素进行了分析与研究，并充分考虑这些因素的影响，给出了一种实用的测试电路。

This paper analyses and studies a few factors affecting the accuracy and thescope of capacitor tests and takes into consideration the influeuces of these factors,thus giv-ing a practical testing circuit.
