Printed Circuit Board Design
Usually an electronics or electrical engineer designs the circuit, and a layout specialist designs the Printed circuit board. The designer must obey numerous PCB layout guidelines to design a PCB that functions correctly, yet is inexpensive to manufacture.
The Circuit Design
The Circuit Diagram, also called the Schematic or Logic Diagram, maps out the electronics and connections in the most readily readable form. The designer needs to do background work while producing the Circuit diagram, researching specifications of components, interaction between components (especially timing and loading) physical packages, and arrangement of connector pinouts. The circuit will often start on paper and finish in Computer Aided Design (CAD) format. The finished circuit diagram, supported by notes if required, is the main reference document for the design.
