In PCB design, wiring is an important step in completing product design. It can be said that the previous preparations are all done for it. In the entire PCB, the wiring design process has the highest limits, the most detailed skills, and the largest workload. PCB wiring includes single-sided wiring, double-sided wiring and multi-layer wiring….
The complete PCB we envision is usually a regular rectangular shape. While most designs are indeed rectangular, many require irregularly shaped boards, which are often not easy to design for. This article explains how to design irregularly shaped PCBs. Today, PCBs continue to shrink in size, and as more and more functions are packed into…
Latency is frustrating, both in our daily lives and in the devices we conveniently use. Propagation delay/time delay inhibits the intended functionality of the device. I say “I am responsible for your product” when I am responsible for the basic functionality of your product. These components are arranged in a specific pattern based on the…
1. Common ground processing of digital circuits and analog circuits Nowadays, many PCBs are no longer single-functional circuits (digital or analog circuits), but are composed of a mixture of digital and analog circuits. Therefore, it is necessary to consider the mutual interference between them when wiring, especially the noise interference on the ground line. The…
The immersion gold board is a PCB board made by the immersion gold process. Most of these immersion gold boards are multi-layer PCB boards. The immersion gold process deposits on the surface of printed circuits a stable color, good brightness, smooth coating, and good solderability. With the nickel-gold plating, the PCB can be used for a long…
What is an HDI stackup? HDI stands for High Density Interconnect. An HDI printed circuit board is characterized by a high density of components and routed interconnections. HDI design is inherently a high-performance design. It features fine lines and spaces (≤100µm), small vias (<150µm), small capture pads (<400µm) and high connection pad density (>20 pads/cm2). The small…
How to Reduce Signal Attenuation in High-Speed PCBs As a signal travels from the source to the load through PCB conductors, the signal is attenuated due to trace resistance and dielectric losses, resulting in energy loss. Signal attenuation is the most common term used when high-speed signals travel across a circuit board. It is one…
