When designing PCBs, there are many small details to pay attention to. Let’s see if you are a detail-oriented person. 1. When calculating the routing length, include the length of the vias and pads that the signal passes through. 2. During routing, avoid right angles and sharp angles that can cause signal reflections. Preferably use … Read more
Abstract: The layout of switch power supply PCBs is an important process in the development of power products. In many cases, a power supply that is perfectly designed on paper may not work properly during initial debugging due to various issues in the PCB layout. This article discusses the basic points of switch power supply … Read more
Silkscreen design is an essential factor in PCB design. The silkscreen on a PCB typically includes: component silkscreen and designators, board name, version number, anti-static symbols, barcode silkscreen, company logo, and other identifiers. Next, let’s take a look at the requirements for silkscreen design in PCB design. 1. Silkscreen Design Requirements The height-to-width ratio of … Read more
PCB Circuit Advanced Schematic Design The advanced design of PCB schematics requires integration of engineering practices, signal integrity, design specifications, and advanced tool functionalities. 1.Modular and Hierarchical Design Modular Segmentation: Divide complex circuits into independent modules based on functionality (such as power supply, MCU, communication interfaces) for easier reuse and maintenance. Hierarchical Schematics: Use hierarchical … Read more
Recently, a long-time friend reached out to me on social media, expressing a hint of helplessness: “Do you have any PCB design work available? I want to take on some side jobs on weekends to supplement my household income.” This friend has been in the electronics industry for many years. Although he is in a … Read more
In the wave of precision and miniaturization of modern electronic devices, printed circuit boards (PCBs) serve as the core carriers of electronic systems, and their performance directly affects the success or failure of products. Solder mask design, as a key part of PCB design and manufacturing, acts like an “invisible guardian” hidden beneath the circuits. … Read more
