這【Strain Gauge】基本上是一片非常薄的金屬銅箔線路,它必須平貼在待測物件上,原則上待測物必須是剛性材料,當待測物發生物理性的變形時就會帶動【Strain Gauge】的「金屬敏感柵」跟著變形,於是驅使「金屬敏感柵」的電阻值發生相應的變化,通過「惠斯登電橋(Wheatstone bridge)」就可以量測到這個微小的阻值變化量,然...

Strain gauge model testing is commonly applied in mechanical and civil engineering to complement analytical, numerical and finite element models and to assess the relative behaviour of components. In biomechanics comparative investigation of product performance in vitro is often obtained by testing models ...
gage】量测应力对PCBA造成的板弯影响后,现在【Strain gauge】量测已经变成是我们公司产品的制程检验标准之一,甚至连RD也已经大部分接受【Strain gage】为其设计参考指标之一,不过大多还局限在制程应力的验证上,深圳宏力捷下一步想推动的是将【Strain gauge】执行到DQ的滚动测试(tumble test)与落下测试(drop test)...
Strain Gauge StrainGaugeMeasurementandTestMethodImprovement StrainGauge 引言何为应变、何为应变规；应变规简单原理如何选择应变规 引言 当今BGA封装的体积越来越小，加上现在对无铅制程的需求，BGA与PCB的连接也因制造过程中的过板弯所导致锡裂发生机率的增加。过板弯导致的可能...
6) strain-gauge test 应变仪测试 补充资料:电阻应变仪 分子式: CAS号: 性质:一般也称电阻应变仪。有线应变仪、箔应变仪、半导体应变仪等。随着变形会发生电阻值变化的应变片按规定方向贴在试件表面,由于试件表面应变造成应变片的电阻值变化。人们用高灵敏度检流计测出电阻值的变化。并用此推得应变值的大小变化...
