You've followed the schematic provided by the chip manufacturer, but your PCB still has issues. It may be unstable, not hitting performance targets, or failing EMC tests. Is it human [...]
What is Dead Copper on a PCB? Dead copper refers to areas on a copper layer of a printed circuit board (PCB) that are unable to conduct electrical current. These [...]
PCB Design Requirements for 5G Applications In 5G applications, the key PCB design requirements include high-frequency, high-speed materials, high-density interconnects (HDI), impedance matching, layer stack-up planning, signal integrity for trace [...]
LEDs are increasingly used in areas like indicators and displays due to their long lifespan and low energy consumption. When replacing traditional lighting sources with LED technology, factors such as [...]
 Importance of Sufficient Separation in High-Frequency Signal Routing Signal routing on a PCB, especially for high-frequency digital signals, requires sufficient separation to minimize crosstalk. When the center-to-center spacing between traces [...]
As the PCB industry develops, the demand for precise control over trace impedance has increased, necessitating stricter control over trace width. PCBs are becoming more reliable and widely used in [...]
Each PCB design should aim to minimize total costs and the potential for DFM issues (mostly a requirement from management, but whether engineers follow through varies by individual). Generally, this [...]
In our previous article, "Experience Formulas in PCB Design" we introduced some practical formulas. Now, let’s dive into a real-world application by focusing on high-speed USB design on a [...]
In electronic systems, the power supply is a critical module responsible for powering other functions. A well-designed PCB layout can optimize power efficiency, reduce heat dissipation issues, and minimize noise, [...]
Can Signal Attenuation Occur Even in PCB Traces with Near-Zero Resistance? When designing high-speed PCBs, signal integrity is a key concern. Signal integrity refers to the ability of a [...]
3W Rule To reduce crosstalk between traces, the spacing between them should be sufficiently large. When the center-to-center distance between traces is at least three times the trace width, approximately [...]
When you learn to design high-speed PCBs, it signifies that you can move beyond simple single-chip circuits and tackle more complex embedded systems. While learning high-speed PCB design involves numerous [...]
