Distortion detecting component, distortion detection system and distortion detecting method

摘要

Problem to be solved: to provide a strain detecting component, a strain detecting system and a strain detecting method capable of detecting a very small strain of the substrate, and capable of validating the effect of the strain on the substrate mounted on the substrate to be more reliable and reliable.The strain detecting component 11 can be mounted on a printed circuit board 12 as a substrate.The strain detecting component 11 comprises a first member 11a as a first portion made of a brittle material and a second member 11b as a second portion capable of applying tensile stress, for example, to the first member 11a.By applying stress to the first member 11a by the second member 11B, the crack generated from the first member 11a can be developed.Diagram
