Some people say that it should be kept. The reasons are probably: 1. Sometimes a large blank is not good-looking. 2. Increase the mechanical properties of the board to avoid uneven bending.
PCB design is a delicate balance of electrical and thermal considerations, with the relationship between current and line width being a cornerstone of reliable circuit functionality. While many empirical formulas, tables, and software tools exist online to guide this aspect of design, this article consolidates the most useful references to assist engineers in optimizing PCB layouts.
Solution Refinement and Layout: As the demand for smaller and more portable electronic devices continues to grow, the design of RF and microwave circuits is shifting towards more compact and efficient solutions. In high-frequency circuit design, the choice of PCB materials is crucial for determining circuit size, performance, and signal propagation characteristics. RT/duroid® 6010.2LM, a […]
Addressing signal integrity (SI) issues early in the PCB design process can streamline the design and eliminate the need for corrective termination devices later. Here, we outline critical steps to maintain signal integrity, from planning through testing.
Mastering these PCB design rules—like efficient grounding, proper trace sizing, and capacitor placement—significantly improves design quality and efficiency. By following these guidelines, you can reduce rework, save costs, and achieve more reliable, higher-quality PCB designs
Electromagnetic compatibility (EMC) refers to the ability of electronic devices to function harmoniously in their electromagnetic environment without causing or being affected by electromagnetic interference (EMI). The goal of EMC design is to enable electronic devices to resist external interference while minimizing the electromagnetic interference they emit to surrounding devices
PCB design involves two critical stages: component layout and circuit connection wiring. The layout is the arrangement of circuit components within the PCB’s wiring area. A well-thought-out layout directly affects the ease of subsequent wiring and significantly impacts the PCB’s overall performance. In addition to meeting circuit functionality and performance requirements, a good layout considers manufacturability, inspection, and maintenance. Components should be placed evenly, neatly, and compactly, ensuring that leads and connections are short, minimizing interference and signal transmission delays.
