KYOWA Strain gauge KFRS series force sensor for PCB

PCBs are used for varieties of products including cellular phones, car navigation systems and digital cameras.
The gages are the self-temperature-compensation gages (SELCOM gages) for evaluating them.

Features

∙ Dimensions of gage base (bondable space to mounted components and narrow parts)
1.2 mm long by 1.1 mm wide (uniaxial), 2.5 mm long by 2.5 mm wide (biaxial or triaxial)
∙ Linear expansion coefficient of 13 x 10-6/ºC, suitable for component-mounted board
∙ Self-temperature-compensation range is made as wide as –30 to 120ºC to satisfy thermal cyclic tests of PCB.

How to bond KYOWA KFRS miniature strain gauges on a PCB

Application:

Stress Measurement During PCB Mounting

PCD-400B Series devices contain a built-in bridge circuit, and can be used to build measurement systems with simple structures. Special software for PCB stress measurement is also available to easily handle everything from measuring strain speed to creating reports.

Security:

The KFGS gages maintains the features of the conventional KFG series of general-purpose foil strain gages, but are RoHS compliant, have improved quality, improved installation work, and new packaging to pursue improved quality and ease of use and performance.

Kyowa offers various types of strain gages so that customers can use the optimal strain gages according to the measurement conditions.
Strain gauges have different effects on the measured value due to temperature changes during measurement depending on the lead wire connection method.
Let's compare the effect on the measured value when hot air is blown with a dryer.

General purpose foil strain gauge for measuring stress.
Can be used with regular steel, stainless steel (SUS631, SUS630), etc.
