1. Design: The design of the circuit board is the starting point of the entire production process. The designer draws the wiring diagram and size requirements of the circuit board based on the circuit schematic and product requirements.

2. Plate making: According to the design drawings, the wiring diagram is formed into transparent film, and then the pattern is transferred to the copper clad plate through darkroom exposure.

3. Etching: Place the copper-clad board into the etching machine and remove the unwanted copper layer through chemical etching, exposing the parts that require wiring.

4. Perforation: After etching is completed, use a drilling machine to puncture the components that need to be welded, and enable the components in the circuit to be connected to the other side of the circuit board through a rod shape.

5. Assembly: By welding technology, the components are pasted onto the circuit board. Proficiency in welding process is required to ensure the quality of welding points and the reliability of connections.

1. Accuracy of circuit diagram: Designers must ensure the accuracy of the circuit diagram, consistency between dimensions and wiring diagrams when making circuit boards, to ensure the normal operation of circuit functions.

2. Selection of PCB materials: Select suitable PCB materials based on product requirements, including considerations of insulation performance, thermal performance, mechanical strength, etc.

3. The anti-interference ability of the circuit board: In order to ensure the stable operation of the circuit, the circuit board needs to have a certain level of anti-interference ability. During the production process, appropriate protective measures should be taken to prevent external interference such as electromagnetic waves and static electricity from affecting the circuit.

4. Requirements for welding process: Welding is one of the most important processes in the production of circuit boards. The welding quality directly affects the reliability and stability of the circuit. Therefore, it is required that the welding process is proficient and reliable, the welding temperature and time are appropriate, and the welding points are good.

can produce high-quality and highly reliable circuit boards, providing assurance for the normal operation of electronic products.
