What is an Automotive PCB?
PCB (Printed Circuit Board) is the abbreviation for printed circuit board, serving as the carrier of electronic components and an essential part of electronic devices. An automotive PCB is 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 [...]
The Advantages and Disadvantages of ICT and FCT in PCBA Testing
Stringent Testing Required Before PCBA Delivery Before delivering a PCBA (Printed Circuit Board Assembly) to customers, it must undergo rigorous electrical and performance testing. FCT (Functional Circuit Testing) and [...]
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 [...]
