1. printed circuit board (PCB)
Printed circuit board is a common circuit board manufacturing process, which uses printing technology to laminate conductive layers and insulating layers. Printed circuit board manufacturing process mainly includes the following links:
1. Preparation of raw materials: including the preparation of raw materials such as substrates, conductive layers, insulating layers and copper-clad layers.
2. Drawing design: according to the circuit design requirements, draw the circuit board drawings, including circuit layout, component layout and pad layout.
3. Printing: The conductive layer and the insulating layer are superimposed together by printing technology to form the basic structure of the circuit board.
4. Etching: By chemical etching, the unnecessary conductive layer is etched away to form the required wiring.
5. Drilling: Drilling holes on the circuit board for installing components and connecting lines.
6. Plug-in: Insert the components into the pads on the circuit board to complete the installation of the components.
7. Welding: Through welding technology, the components and the circuit board are welded together to form a circuit connection.
8. Test: Test the manufactured circuit board to ensure that its quality and performance meet the requirements.
2. Rigid PCB
Rigid circuit board is a common circuit board manufacturing process, which uses rigid materials as the base material, with high mechanical strength and stability. Rigid circuit board manufacturing process mainly includes the following links:
1. Manufacturing of multi-layer boards: Multiple single-layer circuit boards are stacked together through lamination technology to form a multi-layer board structure.
2. The production of the inner layer line: in the interior of the multilayer board, the required line is produced by etching or electroplating.
3. The production of the outer line: in the outside of the multilayer board, the required line is produced by printing or electroplating.
4. Drilling: drilling holes in the multilayer board for installing components and connecting lines.
5. Plug-in: Insert the components into the pads on the multilayer board to complete the installation of the components.
6. Welding: Through welding technology, the components and multilayer board are welded together to form a circuit connection.
7. Test: Test the manufactured circuit board to ensure that its quality and performance meet the requirements.
PCB circuit board manufacturing process is an indispensable part of electronic product manufacturing. With the continuous development of science and technology, PCB circuit board manufacturing process is also constantly innovating and improving. In the future, with the increasing demand for miniaturization, high performance and multi-functionality of electronic products, PCB manufacturing processes will pay more attention to the requirements of high precision, high reliability and high efficiency. At the same time, the application of new materials, new processes and new technologies will also promote the development of PCB manufacturing processes.
