At the beginning of design, engineers first need to work with the customer or project team to understand the project’s needs and technical specifications. They gather and analyze circuit functionality, performance requirements, and any special constraints to form the basis of the design process.

Based on the requirements analysis, the engineer begins to draw the schematic diagram of the circuit. They connect various electronic components according to their functions and conduct circuit analysis to ensure that the circuit design meets the expected performance indicators.

During the component selection stage, engineers select appropriate devices based on circuit requirements and the characteristics of available components. They then place these components on the PCB and optimize the layout to ensure signal integrity and electromagnetic compatibility.

Engineers perform signal integrity and electromagnetic interference (EMI) simulation analysis to verify that circuit layout and design meet expected performance requirements. They may use professional software to simulate the working status of the circuit and detect potential signal interference and timing problems.

After the circuit layout is determined, engineers begin routing design, that is, routing the wires connecting various electronic components. They need to consider signal path length, impedance matching and cross-talk between signals to ensure the layout meets design specifications.

Optimization of physical layout is a critical step in ensuring circuit performance and reliability. Engineers adjust component locations and routing paths to minimize signal transmission delays, cross-talk, and power losses.

After the design is completed, engineers will conduct integrity and reliability verification, including schematic review, design rule check (DRC), electrical inspection (ERC), etc. They may also perform prototyping and testing to ensure the design performs as expected.

Through the above rigorous design process, engineers can effectively design Advanced BT PCBs with excellent performance, reliability and stability, providing a solid foundation for the development and application of electronic equipment.

This choice is crucial because the quality and performance of the substrate directly affects the stability and reliability of the entire circuit board.

Next comes layering and preprocessing. In this step, multiple substrate layers are stacked together and undergo necessary pre-processing to ensure smooth interlayer bonding and surface preparation. The precision and accuracy of this process directly affects the smooth progress of subsequent steps and the quality of the interlayer connection of the final product.

Then comes copper foil preparation and patterning. Copper foil plays a key role in the conductive path in Advanced BT PCB, so the preparation process of copper foil is crucial. At this stage, engineers will cover the surface of the substrate with copper foil and use chemical methods to pattern the copper foil to form the required conductive paths and circuit structures.

Next comes drilling and plating. In this step, engineers use a drilling machine to drill holes in the prepared substrate for subsequent component installation. The drilled surface is then electroplated to enhance connectivity and corrosion resistance. This process is critical to the accuracy and reliability of the circuit board.

Finally comes the etching and final inspection. At this stage, engineers use chemical methods to etch away unwanted portions of the copper foil from the substrate, leaving behind the desired conductive paths and circuit structures. The board then undergoes final inspection to ensure that all process steps have been completed as designed and that no defects exist.
