Circuit design refers to a circuit system designed to meet the requirements of use according to certain rules.
Circuit (English: Electrical circuit) or electronic circuits, Electrical equipment and components such as resistor, capacitor, inductor, diode, triode, and switches, etc.), join together in a certain way, provides a path of overall charge distribution, also called the electric circuits or electrical circuit.
Circuit is generally implemented by PCB Circuit boards, PCB (Printed Circuit Board), Chinese name called Printed Circuit Board, is an important electronic components, electronic components support, and the carrier of electronic electrical connection. Because it is made of electronic printing, it is called "printed" circuit board.
PCB basic design process is as follows: preliminary preparation --PCB structure design --PCB layout -- wiring -- wiring optimization and screen printing -- network and DRC inspection and structure inspection -- plate making.
