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 [...]
What is PCB Warping and How to Resolve It
To ensure accurate placement of SMT components, the PCB must be completely flat. The placement machine must release SMT components at the same height above the PCB for all components. [...]
Do You Really Know All About PCB Via Holes?
When routing needs to switch layers, vias must be added. Vias should be placed whenever ground planes are stitched, high-frequency lines are protected, or the shortest return path is established. [...]
The Role of Bypass and Decoupling Capacitors in PCB Design
In electronics, capacitors are crucial for ensuring the stability and reliability of PCBs. You might frequently see 0.1uF and 0.01uF capacitors used around chips as bypass and decoupling capacitors. Why [...]
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 [...]
