Dimensional measurements of components from different regional standard parts suppliers have repeatedly shown that the quality of guides available on the market is declining worldwide.
This is particularly critical because the size of the parts to be produced with them is decreasing, and the demand for precision in stamping production is increasing significantly. A notable example of this is the increasing replacement
of the USB-A connector by the USB-C connector, which is approximately 30–40% smaller and more difficult to manufacture. The facts and figures presented here illustrate the essentiality of guiding precision for guaranteeing
reliable, controlled production. In the future, this will play an even more central role in the field.
For decades, electronic systems and their stamped components required them to be increasingly miniaturized,
a trend strikingly reflected in the development of well-known generations of USB plugs. The USB-A connector,
introduced in the 1990s, was the standard until around the mid-2010s and is still widely used today.
However, the market has been progressing to the more compact USB-C version. This format is becoming
much more popular, especially in portable systems such as laptops, cameras, and smartphones.
