I need to design a printed circuit board

1 Answer

Answer :

I used to play this game as a radio amateur. But it was for analog technology. Digital is a phenomenon, but usually it is not possible without multilayer connections. Today, there are a number of programs for complex boards. But complex boards also mean perforation. You won't do that at home anymore. Not only the scheme is important, but also the range of components used. Once it didn't matter, the resistance didn't fit horizontally, it went upright, but SMD technology requires precision in printed circuit boards as well.
