PCB Fabrication
Manufacturing a printed circuit board is a complex process that starts with a product concept and ends with a fully functional PCB component. During this process, schematics capture network connections and PCB designers lay out circuits to optimize electrical characteristics within design constraints. After soldering the components to the board and completing assembly testing and verification, the circuit board is integrated into the system.
