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…
