Techniques for Attaching Leadwires
to Unbonded Strain Gages

In general, solders having the lowest melting point which satisfies test temperature and adhesive cure temperature requirements should be selected. This is because an unbonded strain gage backing has a much lower tolerance for high soldering temperatures.
