PCB component layout is not a matter of personal preference; it follows certain rules that must be adhered to. In addition to general requirements, some special components have different layout requirements. Layout Requirements for Crimping Components 1) For crimping components with bent male/female pins, there must not be any components higher than 3mm within 3mm … Read more
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
1 Component Placement When placing components, it is essential to follow the signal paths of the schematic and provide space for routing. Additionally, adhere to the following placement rules: Power components should be placed compactly together, with appropriate decoupling to ensure power integrity. Decoupling capacitors should be placed as close as possible to each component. … Read more
AC Wiring Section: The creepage distance and electrical clearance are related to altitude, surge voltage, working environment, insulation voltage, etc. Specific values can be referenced from standards. Below are practical experience values summarized based on standards: a. For AC-DC power supplies (taking those without PFC circuits and an input rated voltage range of 100-240V as … Read more
This article highlights The core of PCB layout is “signal flow” and “power flow”. Conventional manual dragging can easily lead to mistakes, making it difficult to find the right placement for components like capacitor R1 among a sea of wires; the quick layout function helps you place components with one click, following certain design rules. … Read more
Numerous application cases of Industrial, Scientific, and Medical Radio Frequency (ISM-RF) products indicate that the printed circuit board (PCB) layout of these products can easily exhibit various defects. It is often found that the same IC installed on two different circuit boards can show significant differences in performance metrics. Variations in operating conditions, harmonic radiation, … Read more
In Buck-type DC-DC power circuits, the PCB layout is crucial for the implementation of circuit functionality and achieving good performance metrics. Key Layout Considerations for Current Loops The two loops in the diagram act like antennas; the larger the loop area, the more severe the electromagnetic interference (EMI). Input Loop (Vin-Cin-IC-GND): The current in this … Read more
In a DC-DC power circuit, the layout of the PCB is crucial for the implementation of circuit functionality and achieving good performance metrics. Today, we will take the Buck circuit as an example to analyze how to perform a reasonable PCB layout and the considerations in the design. ↓ Click to watch the video explanation … Read more
In the PCB design process, layout is a key factor that determines circuit performance, manufacturability, and aesthetics. Mastering the layout operation commands and shortcuts in Altium Designer can significantly enhance work efficiency, allowing you to handle complex circuit boards with ease. 🛠️ 1.
