There are many factors that engineers need to consider. This article organizes some detailed issues that need attention in PCB layout. Let’s see if you are aware of all of them! 01Layout of Special Components Heat-generating components should be placed in positions favorable for heat dissipation, such as the edges of the PCB, and away … Read more
Brothers, what is the biggest fear when designing a PCB? It’s not about routing issues, but rather when the board comes back and you power it on—there’s a “bang” or it simply doesn’t work! Those who understand know the feeling. Today, I will summarize the major pitfalls in PCB layout that I have encountered, seen, … Read more
In the field of embedded hardware design, the DDR power circuit serves as the core power supply unit, and its design quality directly affects chip performance and long-term device stability. The RK3588, as a high-performance processor, has stringent requirements for the layout, routing, and component selection of the VCC_DDR power circuit. This article combines official … Read more
The application of AI technology has increased the requirements for product computing power, speed, bandwidth, low latency, and low power consumption. Due to the increased switching frequency of transistors, parasitic inductance exists in power lines and PCB traces, which can easily cause delays, leading to voltage fluctuations and noise. The decoupling capacitors in chips can … Read more
