What are The Technologies Required During PCB Processing?
Circuit Design Technology: This is the basis for making PCBs, including circuit schematic design and circuit board design. Circuit schematic design is the logic of the circuit relationship and circuit components connected to draw a diagram, in order to facilitate the subsequent circuit board design. Circuit board design is based on the circuit schematic diagram, the circuit components and connections drawn to the PCB board, and take into account the structure of the board, layout, wiring and other factors. Designers need to master circuit fundamentals, electronic components, signal integrity analysis and other related knowledge, as well as proficient use of circuit design software.
Computer-aided Manufacturing Technology: Through computer-aided manufacturing software, the PCB manufacturing process can be automated and intelligent. These software can carry out data management, production planning, process design and other operations to improve production efficiency and product quality. For example, CAM software can be based on circuit board design data, automatically generate the manufacturing process and processing parameters, and optimization and calibration to improve manufacturing accuracy and efficiency.
Mechanical Processing Technology: In the process of making PCBs, drilling, cutting, bending and other mechanical processing operations are required. Technicians need to master the use of relevant mechanical processing equipment and tools, as well as the processing process and precision control and other aspects of knowledge. For example, the drilling machine can drill the circuit board, the cutting machine can cut the circuit board, the bending machine can bend the circuit board. These machining operations are essential to ensure the quality and reliability of the PCB.
Surface Treatment Technology: In order to improve the conductivity and corrosion resistance of PCBs, surface treatment is required. This includes electroplating, chemical plating, impregnation and other surface treatment methods, as well as surface coating and insulation treatment. Technicians need to master the use of relevant surface treatment equipment and materials, as well as the surface treatment process and quality control and other aspects of knowledge. For example, electroplating can be plated on the metal surface to improve conductivity and corrosion resistance; insulation treatment can be achieved by coating insulating materials to achieve isolation between different areas of the circuit board.
Quality Testing Technology: In order to ensure the quality and reliability of PCBs, quality testing is required. This includes electrical performance testing, mechanical performance testing, appearance testing and other aspects of testing methods and techniques. Technicians need to master the use of relevant testing equipment and tools, as well as testing standards and quality control and other aspects of knowledge. For example, electrical performance testing can be tested through the test instrument to detect and evaluate the electrical performance of the circuit board; appearance testing can be visual inspection equipment to detect and categorize the appearance of circuit board defects.
Reliability Analysis Technology: In order to improve the reliability and stability of the PCB, reliability analysis is required. This includes environmental adaptability analysis, life prediction and other aspects of the analysis methods and techniques. Technicians need to master the use of relevant reliability analysis software and tools, as well as reliability standards and quality control and other aspects of knowledge. For example, environmental adaptability analysis can be simulated under different environmental conditions of the test data, to assess the performance of the circuit board in different environments and adaptability; life prediction can be accelerated aging test and other methods to predict the life of the circuit board.
These technologies are the production of high-quality, high-reliability PCB must master the key technologies. Technicians need to constantly learn and master new technologies and knowledge to continuously improve production levels and work efficiency.
