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
▼ Follow the public account below for more information ▼ In high-voltage PCB design, attention must be paid to electrical clearance and creepage distance in switch mode power supply PCB design; insufficient distance can lead to leakage. General standards (varying by industry, such as lighting, electric vehicles, etc.) require certified products: design according to standard … Read more

▲ Click the public account card above to follow for more information ▲ A packaging library mainly consists of two parts: pads and graphics. The position and size of the pads determine the soldering conditions, while the graphics serve to visually represent the component status, assisting in design and guiding component assembly. We have discussed … Read more
[Click on the public account above] ▲Get a free collection of learning tools▲ In PCB design, pads are a very important concept, and PCB engineers are certainly familiar with them. However, despite their familiarity, many engineers have only a partial understanding of pads. Today, let’s explore the types of pads and the design standards for … Read more
Many people have experienced making mistakes in PCB packaging—either making it too large or too small, or even having components obstructed, which leads to issues when soldering components after the PCB is manufactured, sometimes requiring manual wire connections; in severe cases, it may even result in the entire board being scrapped. For example, the U8 … Read more
Recently, a friend asked me if I knew any PCB design masters who take apprentices. I replied that I do, and asked if he wanted a recommendation. “Is there a fee?” he asked, which caught me a bit off guard. “Yes, the specific fee needs to be discussed with the master,” I answered. He countered, … Read more
