Printed Circuit Board Design Resources & Tips
Printed circuit board/boards
By definition, a printed circuit board (or PCB) electrically connects and mechanically supports electrical components or electronic components using pads, conductive tracks, and other features etched from one or more sheet layers of copper laminated between or onto sheet layers of a non-conductive substrate.
Generally, components are soldered onto the PCB to both mechanically fasten and electrically connect them to it.
The alternatives to PCB comprise point-to-point and wire wrap construction, both once popular but now rarely used. PCBs require additional design effort to lay out the circuit, but assembly and manufacturing can be automated. (more…)
