After the delivery of a previous design project, due to an operational error by the on-site debugging personnel, the exposed wire ends touched the circuit board (which was coated with a conformal coating) when the rear panel of the device was opened, ultimately causing a short circuit. The feedback from the site indicated that the … Read more
In the process of developing and producing electronic products, one may encounter the scenario of needing to disassemble an existing PCB circuit board to analyze the circuit layout, component selection, and signal routing. Below, we will discuss an efficient process for disassembling a PCB circuit board, which we hope will be helpful to everyone. 1. … Read more
The basic task of interference immunity design is to ensure that the system or device does not malfunction or lose functionality due to external electromagnetic interference, and does not emit excessive noise interference to avoid affecting the normal operation of other systems or devices. Therefore, improving the system’s interference immunity is also an important aspect … Read more
RK3588 Baseboard Design： Last night around 11:00 PM, a client contacted me: 2 Ethernet ports, 1 PCIe hard drive, MIPI camera, TF card, USB, HDMI, asking for a schematic and PCB design to help evaluate the price. After sending this request, this person did not read the message anymore? They have disappeared～
In PCB (Printed Circuit Board) design, factors such as signal transmission stability and impedance matching are typically considered. Choosing the appropriate stacking scheme is crucial to meet design requirements. In certain cases, especially when designing six-layer boards, a special design scheme known as ‘pseudo eight-layer’ may be adopted. The ‘pseudo eight-layer’ actually refers to a … Read more
Capacitors play a crucial role in high-speed PCB design and are typically the most used components on a PCB. In PCBs, capacitors are generally categorized into filtering capacitors, decoupling capacitors, and energy storage capacitors. 1. Power Output Capacitors, Filtering Capacitors We usually refer to the capacitors in the input and output circuits of the power … Read more

Scope … Read more
Previously, I wrote an article on my blog titled “Why Convert PCB Files to GERBER Files and Drill Data for PCB Manufacturers”. That article simply explained why this is necessary. In this article, I will discuss how to convert PCB design files into the corresponding Gerber files and some common pitfalls to avoid. Many engineers … Read more
