High-Speed USB Design on a Two-Layer PCB
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 [...]
Understanding Insertion Loss in High-Speed PCB Design
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 [...]
Key PCB Design Rules
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 [...]
High-Speed PCB Design: Impedance Matching Essentials
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 [...]
Series Resistors in PCB Design for USB Connections
In circuit design, it's common to see resistors in series with the data lines (D+ and D−) of USB interfaces on schematics. These resistors are often explained as being for [...]
What is the role of the PCB half-hole?
The PCB half hole is widely used in the PCB manufacture of modern circuit boards, which can make the connection between electronic circuit board components close, and also enhance the [...]
Experience Formulas in PCB Design
In PCB design rules, there are numerous empirical formulas for designers to reference. However, is there a simpler method to address practical issues? Even if a ground copper plane has [...]
PCB Design: Unveiling the Misconceptions of Right-Angle Routing
It is widely known that PCB routing should avoid right angles or acute angles. This rule is emphasized in textbooks and company technical specifications, and some even use it as [...]
