BONDABLE TERMINAL PADS

Terminal pads serve 2 main purposes. First, they act
as intermediate points for attaching ribbon leads of
thin-gage wire to heavier instrumentation wires. Second,
they give stress relief to strain gage systems. When the
heavy instrumentation wire moves, the terminal pad protects
the strain gage. Carrier is polyimide with a thickness of

0.075 mm (0.003"). Minimum bending radius is 2 mm (0.079").
Maximum temperature is 220°C (428°F).
