Intel Strain Measurement Methodology for Circuit Board

Intel measures strain using strain Gages. Strain gages work by measuring the resistance change that occurs when a metal is strained. A stack of three gages (a rosette) allows for measuring the strain in three directions and to calculate the strain in any direction. Some of the commonly available rectangular rosette strain gages are included below.

Measuring strain during a cylindrical grinding process

 · The grinding process in which the sensor-integrated work-piece was used is a cylindrical grinding process. In the pro-cess the rotating grinding wheel plunges into the surface ofthe workpiece up to a pre-defined depth the so-called totaldepth of cut ae. After this is reached the sensor-integratedworkpiece starts rotating around its center for one completerevolution so that the full depth of cut aeis removed fromthe workpiece surface. External forcesFt andFnduring theprocess induce internal material loads such as strain intothe workpiece through its surface. The impact of the inter-nal loads residing in the workpiece leads to material modi-fications and can be measured from indicators like residualstress.
