Test methods for electrical materials, circuit boards and other interconnection structures and assemblies - Part 2-720: Detection of defects in interconnection structures by measurement of capacitance
电气材料、电路板和其他互连结构和组件的试验方法.第2-720部分:通过测量电容检测互连结构中的缺陷
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.
