Soldering Practice Kit SMD/SMT Training for beginners

SMD/SMT Soldering Practice Kit — CD4017 Rotating LED Trainer Sharpen your surface-mount soldering skills with this hands-on DIY practice board, built around the classic CD4017 decade counter and NE555 timer IC. Once assembled, the board drives a rotating LED light pattern — giving you a working circuit that demonstrates your soldering came together correctly. Technical specifications: Operating voltage: 3–12V DC PCB dimensions: 86 × 54 mm Components included: 125 pieces across 274 solder joints IC package: standard SOIC and discrete SMD passives (0805 resistors, capacitors, LEDs) Estimated build time: ~35 minutes for experienced builders What you’ll practice: The kit walks you through real-world SMT techniques — pad tinning, component placement, drag soldering, and inspecting joints under magnification. The mix of 0805 passives, LEDs, and SOIC-packaged ICs covers the most common footprints you’ll encounter in modern electronics repair and prototyping. Build quality: The PCB is manufactured to international standard sheet specifications, with strong thermal resistance against fire drop and repeated rework attempts — useful while you’re still dialling in your iron temperature and flux technique. (Not Included)Powered by 3–12V via standard battery pack or bench supply, it’s a self-contained project that doubles as a desk ornament once finished. Ideal for makers transitioning from through-hole to SMD work.
