Cracks in Printed Circuit Boards (PCB)
Cracks in PCBs — brittle fractures in solder and even across components, particularly around BGAs — can be induced by in-circuit test fixtures and during assembly, burn-in and testing,...

Diaphragm Patterns: Circular and Linear
Classic diaphragm strain gages employ four gage grids arranged to take advantage of the unique bell shaped tension/compression strain distribution on a pressure diaphragm. When these gages are bonded...

Making Any Measurement Simple
The technical literature on strain measurement can make the subject appear complex and confusing. Indeed, measurements sometimes are complex and confusing. But more often than not they are...

Horseshoe Shape As a Strain Relief Loop.
A bondable solder terminal placed adjacent to strain gage solder tabs is necessary for strain gages where the tabs may be too small to directly solder the instrument cable.  Use of bondable...

Shear Patterns: Single Grid and Dual Grid
The sensing grid in shear pattern strain gages is angled at 45° to the long axis of the gage. These sensors are designed to facilitate reliable and accurate torque, shear and torsional load...

The effect of short range order on the thermal output and gage factor
OVERVIEW     The operating characteristics of resistive metal foil strain gages are influenced by many parameters,  probably the most fundamental of which are the backing...

Strain Gage Installation Tape
In this video, Darryl  and Tom demonstrate the importance of choosing the right installation tape for handling strain gages, and discuss why it is not recommended to use just any PTFE tape,...

0° - 90° Patterns: Dual Grid
Bi-axial strain gages, often referred to as Poisson gages, are 90° tee rosette gages, aligned with the principal strains in uniaxial stress loading, for use in column load cells or simple...
