A Primer on Small Wire Crimping
Trends toward miniaturization and electronification, especially in the automotive industry, are driving increased demand for small wire terminations. TE Connectivity defines small wires as anything that has a wire cross-sectional area of 0.35 mm2 (22 AWG) and smaller. There are several problems inherent to small wire crimping due to the small size of the wire, terminal, and tooling. This white paper describes some of these challenges of small wire terminations and outlines how to overcome them. Traditional inspection methods apply to small wires and large wires alike. The article also discussesß crimp height inspection, tensile tests, and visual inspection as well as cross sections.
