Introduction

It has become common practice to employ bondable printed-circuit terminals between the main leadwire and the relatively small and delicate jumper wires to the strain gage. The primary purpose is to provide an anchor for both sets of leads, and to prevent forces transmitted along the main leadwire system from damaging the strain gage or degrading its performance. In order to obtain maximum benefit from the use of these terminals, they must be installed with care and knowledge of their limitations. Otherwise, the terminal can be a source of performance degradation for the entire installation.

Micro-Measurements printed-circuit terminals are produced from 0.0014 in (0.03 mm) electrolytic copper foil bonded to a carrier of either polyimide film or fiberglass-reinforced epoxy. Micro-Measurements manufactures both types in a wide variety of configurations. The following instructions will assist greatly in obtaining proper performance from bondable terminals.
