Prototype Circuit Board

Prototype Printed Circuit Boards are early versions of electronic circuits. The first revisions of these boards usually have errors and require debug and test. Electronic product manufacturers (OEMs) typically send the files produced by their schematic capture package to a circuit board FAB or Prototype house for to be built. Often so-called quick turn PCB […]
