Firstly, circuit board production usually starts from the design phase. Based on the circuit diagram and requirements provided by the customer, design the circuit board using computer-aided design software. The designer will determine the layout and interconnection of various components on the circuit board based on its functionality and size requirements.

Next, the designer will transfer the designed circuit board files to the plate making engineer. The plate making engineer will use techniques such as photolithography and etching to transfer the designed circuit diagram pattern onto a copper foil covered substrate. This process requires precise operation and high-quality equipment to ensure the accuracy and quality of the circuit board.
