Drones consume a significant amount of energy during flight, especially for small devices. To address this issue, drone PCBA is designed to be more compact, denser, and faster, enabling more functions in a smaller space. Signal Integrity Issues in Drone PCBA From aerial photography to package delivery, drones are changing the way we live and … Read more
0 Introduction As the core hub and interaction interface of the entire system, the reliability of embedded control systems directly affects the overall operational efficiency of the system. Once a failure occurs, it not only prevents operators from performing their tasks normally but can also lead to a complete functional paralysis of the entire system. … Read more
“ In the previous article (How to Control Common Impedance Interference on PCBA? – Reducing Common Impedance), we mainly discussed how to reduce interference from the perspective of lowering common impedance. However, in the design of PCBA, there are many limitations to reducing common impedance, such as the non-zero impedance characteristics of conductors. If we … Read more
Circuit boards are one of the fundamental components of modern electronic devices. Various electronic components on the circuit board are connected by metal wires, forming complex circuits. Grounding is crucial in these circuits. This article will introduce the basic knowledge related to grounding in circuit boards to help readers better understand the design and manufacturing … Read more
In a Profibus-DP network, the bus length is one of the key factors affecting system stability. As the bus length increases, signal attenuation, delay, and interference also increase, which changes the requirements for termination resistors. Today, we will discuss in detail how to correctly choose and install termination resistors for different lengths of Profibus-DP buses. … Read more
In order to adapt to the rapid update of electronic products, product design engineers tend to choose AC/DC adapters that are easy to procure in the market and directly install multiple DC power supplies on the system’s circuit board. Since the electromagnetic interference generated by switching power supplies can affect the normal operation of electronic … Read more
Layout In design, layout is an important aspect. The quality of the layout directly affects the wiring results, so it can be said that a reasonable layout is the first step to successful PCB design. Especially pre-layout, which is the process of considering the entire circuit board, signal flow, heat dissipation, structure, and other architectures. … Read more
Introduction The RS-485 bus is widely used in industrial communication, but harsh industrial environments can lead to external interference, such as Electrical Fast Transients (EFT), which affect its stability. This article explores how to test and mitigate the interference of EFT on the RS-485 bus. Sources of Pulse Group Interference In industrial control environments, disturbances … Read more
In the field environment of Profibus, we use a variety of systems, and the devices we face interference from are diverse, so the sources of interference are also varied. Many failures caused by interference are more difficult to troubleshoot than other faults. Before troubleshooting interference failures, we need to understand the types of interference. In … Read more
In the field environment of Profibus, the systems we use are diverse, and the devices we are interfered with are varied, so the sources of interference are also peculiar. Many failures caused by interference are more difficult to troubleshoot than other failures. Before eliminating interference faults, we need to understand the types of interference. To … Read more
