Printed circuits, the next generation…<br>going back to the future
Printed circuits are a fundamental element part of virtually all electronic assemblies and have been since their origins. The moniker 'printed circuit' appears to have first come into broad use in the mid 1940s.
It was an accurate description of the techniques used at the time to create these, then new, interconnection devices. It remains an apt term today. However, because in the early going many printed circuits were actually created by printing conductive inks directly on to insulating substrates using screen printing technologies, the term was especially apropos. Moreover, in those early days the same printing methods were often used to print passive devices, most often resistors. Capacitors, however, were a recognized option.
