标准摘要
[中文适用范围]： 本部分IEC 61189提供了一种通过测量导体走线与接地平面之间的电容来评估电路板特定特性的方法，可用于将测试样本与参考板进行定性比较。该方法不适用于定量测量和符合规范的评估。 [外文原描述]： IEC 61189-2-720:2024 provides a method to evaluate specific characteristics of circuit boards by measuring the capacitance between conductor traces and a ground plane and can be used for qualitative comparison of a test specimen to a reference board. This method is not intended for quantitative measurements and for assessment of conformity to a specification.
