Notes on PCB software and hardware design

The design of a Printed Circuit Board is a complex and meticulous process that requires consideration of multiple factors to ensure the effectiveness, reliability, and performance of the design. Choose appropriate materials for the combination of soft and hard boards according to the application requirements. Consider the electrical, mechanical, thermal, and processing properties of the materials to ensure that the selected materials meet the design requirements. Layer planning requires a reasonable planning of Multi Layer PCB based on circuit complexity and signal transmission requirements. Ensure reliable electrical connections between layers, while also considering heat dissipation and wiring space. When wiring, try to minimize the length and intersection of the wiring to reduce noise and interference. Pay attention to the rationality of wiring width and spacing to meet the requirements of electrical performance and mechanical strength. Reasonable grounding design is crucial for suppressing electromagnetic interference and improving signal quality. Ensure that the grounding wire width is sufficient, the grounding path is short and direct, and avoid forming a loop. Consider the heat generated during the operation of the Printed Circuit Board Assembly, and ensure that the components work within the allowable temperature range through reasonable thermal design and heat dissipation layout.
