— Two Months — I Turned a ‘Draft’ into A Flying Homemade Drone A Mechanical Sophomore’s ‘Flight Test Journal’ Introduction “Can you believe it? Two months ago, I couldn’t even hold a soldering iron steadily, and now I can make my own drawings ‘fly’.” As a sophomore in the School of Mechanical and Automotive Engineering, … Read more
Some unknown models of ferrite cores in hand should indeed be screened. At the very least, it is necessary to determine whether they can be used in the shortwave band. (Some were salvaged from broken computer power supplies.) Prepare the components. Arrange the layout of several components on the perfboard. Soldering. Take out two unknown … Read more
4. PCB Prototyping and Soldering JLCPCB EDA not only supports one-click ordering for PCB prototyping at JLCPCB Group’s factories but also allows users to export commonly used PCB processing files such as Bill of Materials (BOM), Gerber files, coordinate files, etc., for production at any other PCB manufacturer. 1. PCB Prototyping Click on the main … Read more
For DIY enthusiasts, a soldering iron is an essential tool. Manually applying solder really tests your skills; I can’t manage it well, always feeling like I don’t have enough hands—holding the wire, gripping the soldering iron, and trying to apply solder all at once is a terrible experience. That’s why I discovered this project that … Read more
Professional Terminology in the PCB Industry (A-C) DDate Code Production DateRefers to the production date of the product, usually expressed in a 4-digit format (YY+WW), presented on the board through etching or printing, and typically displayed alongside the company logo and UL certification for identification or subsequent traceability.DES (Development–Etching–Stripping) is an abbreviation for development-etching-stripping, a … Read more
Click the blue text to follow us Today, let’s discuss an important topic in professional PCBA processing: why all reliable factories insist on “soldering before separation”? This question sounds quite technical, but it actually relates to product quality, efficiency, and cost. Whether you are a newly entered engineer or a purchasing manager looking for PCBA … Read more

Today, while in production, I suddenly thought of an interesting topic that might spark controversy and complaints among many production engineers! However, I would still like to hear everyone’s opinions! Do you “cut the pins”? This means, do you cut the long pins of the component? Everyone will surely say, aren’t you stating the obvious? … Read more
In complex PCB design, there is a seemingly insignificant yet crucial “small role”—the jumper. It acts as a “bridge” in the circuit, silently connecting various components and solving layout challenges. But did you know? Improper use of jumpers can lead to the collapse of the entire circuit! Today, we will unveil the classification, functions, and … Read more
