Once an electronic circuit has been designed on paper (or simulated in software), the next obvious step is to connect components together and see if the physical circuit works as one wishes. In some cases, one might explore changes to component values, or make structural changes to the circuit based on what one actually sees. It's also the case that often one wants to use the circuit (or demonstrate it) over a period of time. This document discusses different methods for creating physical realizations of electronic circuits for various needs.
