Author | Danner Dan During the process of performing signal integrity (SI) and power integrity (PI) simulations in CST PCB Studio, it may be necessary to modify the imported PCB. Modifications to signal traces, nets, stackups, vias, and padstacks can be made using the CST PCB Studio’s Edit ribbon, as shown in the figure below. … Read more
PCB Modular Layout Approach In the face of increasingly integrated hardware platforms and complex electronic products, PCB layout should adopt a modular mindset, requiring modular and structured design methods in both hardware schematic design and PCB routing.As a hardware engineer, under the premise of understanding the overall system architecture, one should consciously integrate modular design … Read more
The ground plane and power plane are large conductive areas in PCB design with various purposes. The ground plane provides a common reference point for electrical signals and serves as a return path for current. The power plane transmits power voltage to various components on the circuit board, helping to evenly distribute power across the … Read more

Is it possible not to place silkscreen position numbers on a PCB? The silkscreen position number is mainly for convenience during manual soldering or prototype debugging stages, as it visually indicates the component positions, facilitating assembly, maintenance, and testing, primarily used in the prototype phase. It is indeed possible to manage without position numbers when … Read more
1. Determine the Scheme and Purpose Hello everyone, today I will introduce the LHA7668 chip from the F4 series development board, which is a domestic, 24-bit, 8-channel differential, and 16-channel single-ended high-precision low-power ADC chip. The goal is to design a circuit board to meet the requirements for 16-channel single-ended acquisition or 8-channel differential acquisition.The … Read more
