![]() ![]() But that of the service is an option for a final circuit, which has passed all the tests and perhaps needs to go into production, even for small runs. The high road of the prototype, which can also become final, is that of the PCB (Printed Circuit Board), which is usually made by a professional service, with costs that nowadays are more or less within the reach of every pocket. Prototyping is done with breadboards or multi-hole matrix PCBs, but these are almost always circuits that are difficult to consider definitive, although some people manage to craft well-done designs with these media. In these cases, CNC-milling of a printed circuit could be considered as a valid alternative for accuracy, ease of implementation and, most importantly, for giving a very fast way to have your beloved board finished and ready for soldering!Īnyone involved in practical electronics, whether for pleasure or work, sooner or later "runs into" the need to make a circuit board. ![]() For different reasons, the chemical etching may also be discarded. For prototyping or very small-volume production purposes, the use of external PCB services may become expensive or, to the very least, turn out to be a time-consuming route.
