When designing multi-layer PCBs, the stackup isn’t just about layers—it’s about signal integrity, EMC, heat dissipation, and even cost control. Here’s a practical, real-world guide to PCB stackup rules that actually matter in your daily work. 1. What Are PCB Stackup Rules? In simple terms, stackup rules define how each layer in a multi-layer PCB is arranged and what role it plays. ...

A Practical Breakdown for U.S. Manufacturers If you’re in electronics manufacturing—or planning to get into it—chances are you’ve heard of SMT (Surface Mount Technology). But how much does it actually cost to build a full SMT production line? And what equipment do you need? Whether you’re planning a small-scale operation for LED lighting modules, FPC assembly, or full LCD backlight bar production, here’s a straight-up, realistic look at what it takes to set up an SMT line in 2025—from equipment breakdown to budgeting, especially if you’re considering importing second-hand machines from Asia. ...
A Practical Guide to Surface Mount Technology (SMT) Covering Solder Paste, Reflow, Components, and Process Control 1. Standard SMT workshop temperature is 25°C ±3°C (77°F ±5.4°F). 2. Required tools for solder paste printing include: solder paste, stencil, squeegee, stencil wipes, lint-free cloth, cleaning solvent, and a paste spatula. 3. Common solder paste alloy: Sn/Ag/Cu 305 (96.5/3.0/0.5), melting point: 217°C (422.6°F). 4. Solder paste contains two main components: solder powder and flux. 5. The flux removes oxides, breaks surface tension, and prevents re-oxidation during soldering. 6. Typical volume ratio of solder powder to flux: 1:1; weight ratio: 9:1. 7. Always follow FIFO (first-in, first-out) when using solder paste. Two required steps before use: bring to room temperature and stir thoroughly. 8. For moisture-sensitive devices (MSDs), the humidity indicator card (HIC) must show blue to proceed with assembly. 9. Common stencil manufacturing methods: etching, laser cutting, electroforming, and nano-coating. Among them, laser-cut stencils are reworkable. 10. SMT stands for Surface Mount Technology – attaching electronic components directly onto the surface of PCBs. ...
