Description: This edition addresses these new elements of the printed circuit processes, both revolutionary
and evolutionary, while still maintaining its foundation on the basics of the technology.No
matter how sophisticated the leading edge of the technology becomes, at the core of all
printed circuits is the plated-through hole in its various forms. Platform: |

Description: lectronic circuit design can be divided into two areas: the first consists in designing a
circuit that will fulfil its specified function, sometimes, under laboratory conditions the
second consists in designing the same circuit so that every production model of it will
fulfil its specified function, and no other undesired and unspecified function, always, in
the field, reliably over its lifetime. When related to circuit design skills, these two areas
coincide remarkably well with what engineers are taught at college − basic circuit
theory, Ohm’s Law, Thévenin, Kirchhoff, Norton, Maxwell and so on − and what they
learn on the job − that there is no such thing as the ideal component, that printed circuits
are more than just a collection of tracks, and that electrons have an unfortunate habit of
never doing exactly what they’re told-lectronic circuit design can be divided into two areas: the first consists in designing a
