Backed by responsive customer support, it’s a must-have for aspiring electronics pros and hobbyists alike. ## Description Working principle: Since the voltage across capacitors C1-C9 cannot change abruptly when powered on, the 2nd pin of NE555 is at a low level, and the 3rd pin of the output terminal is at a high level. The current is charged to C1-C9 through R61-R70 and RP1-PR5. When the voltage to 2/3 of power voltage, the level of pin 3 of the output terminal changes from high to low, the internal discharge of NE555 is turned on, and the capacitors C1-C9 are discharged through pin 7 of NE555, until the voltage across C1-C9 is lower than 1/3 of the power voltage, the level of pin 3 of NE555 changes from low level to high level, and C1-C9 is charged again, thus forming a circular oscillation. Changing the size of RP1-RP5 can change the output frequency of the oscillator. The NE555 clock oscillation signal is continuously added to the 14 pin of the 4017. There are 10 transistors connected to the output terminals of the 4017, which to drive the 10 LEDs. Under the action of the clock signal, a high level is generated in turn, then L1-L10 are lit in sequence, forming the effect of a running water lamp. After the SMD components are soldered, power on to form a running water lamp to detect the effect of the soldering Review: High qualitypractice - High quality pcb and plenty of different parts in different sizes. Start with the 20 1206 resistors after you sort and identify each part strip (see picture). Work your way from big to small. It takes just a TINY dab of solder paste! Tiny! Need flux and solder paste and heat gun. You can do it with a small solder iron with tiny tip. Magnification required. Update: like I said it is good practice! The lights did not work probably because of shorts caused by too much solder paste. It takes WAY LESS than I put on there! Review: Arrived quickly. Great customer service - You’re going to get exactly what you expect which is a great kit to learn to solder. There was an issue with one of the components in my package but they were quick to resolve the issue! ## Features - 【SMD/SMT Components Soldering Practice Board】: Input voltage: DC5V. The positive pole is connected to +, and the negative pole is connected to -. After the SMD components are soldered, power on to form a running water lamp to detect the effect of the soldering. - 【Before Soldering】: Some SMD components are relatively small, be careful not to lose them. The side of the diode with the green dot is the negative electrode. This electronic soldering kit is not a finished product, it need to be soldered by yourself. Please refer to the English instructions include in the package. If you have any questions, please contact us first for professional help. - 【Great Soldering Science Project】: This soldering DIY kit help you understand the basics of working with printed circuit boards and become familiar with a variety of electronic components, and practice soldering skills enjoyably for you and your kids, or students, or DIYers. - 【Easy to Assemble】: The connection that was clearly mapped and labeled on the board makes it easy to assemble. And you can refer the marks on PCB board to soldering each component. If it can't work after soldering, please contact us for support. - 【Perfect After-Sale Service】: Please read the User Manual before installing. Our policy is to make our customers happy. If you are not 100% satisfied, just contact our customer service, we will refund your money. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09YQDF942 | | Age Range Description | Kid | | Best Sellers Rank | #376,072 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #988 in Soldering Stations | | Brand Name | Ovenot | | Customer Reviews | 3.9 out of 5 stars 58 Reviews | | Educational Objective | Soldering Skills, Electronic Components Understanding | | Included Components | Soldering kit | | Item Dimensions | 4.75 x 2.75 x 1 inches | | Item Type Name | SMD Soldering Kit | | Item Weight | 0.03 Kilograms | | Manufacturer | Dingdong Store | | Manufacturer Maximum Age (MONTHS) | 1200.00 | | Manufacturer Minimum Age (MONTHS) | 144.00 | | Material Type | Metal, Plastic | | Theme | Electronics | ## Images ![SMD/SMT Components Soldering Practice Board Electronic Project Kits DIY Soldering Kit Skill Training Board Led Transistor SMD Soldering Kit SMD Soldering Kit - Image 1](https://m.media-amazon.com/images/I/71q4O39PZlL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ High qualitypractice *by K***N on June 10, 2024* High quality pcb and plenty of different parts in different sizes.

Great customer service *by B***H on October 16, 2022* You’re going to get exactly what you expect which is a great kit to learn to solder. There was an issue with one of the components in my package but they were quick to resolve the issue! ### ⭐ These Kits Are a Mess *by W***S on August 9, 2024* I purchased one of these and parts were missing. I ordered a replacement and it ALSO had wrong or missing parts. There are NO instructions. The images of the product are NO HELP identifying parts, as the photos are blurred and the part numbers cannot be read ! Yes, you can practice soldering, but do NOT expect a functioning product, as the parts seem to be thrown at random into a bag, and who KNOWS what you are putting on the board. I have a LOT of professional pcb experience and could NOT make sense of anything in this kit. I do NOT recommend purchase. Instead, drive down the road and throw your money out the car window. You are welcome. ## Frequently Bought Together - SMD/SMT Components Soldering Practice Board Electronic Project Kits DIY Soldering Kit Skill Training Board Led Transistor SMD Soldering Kit SMD Soldering Kit - Gikfun DIY SMD/SMT Components Practice Board Soldering Skill Training Kit AE1173 - Gikfun DIY SMD SMT Welding Practice Soldering Skill Training Board Ek7028 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/448029875-smd-smt-components-soldering-practice-board-electronic-project-kits-diy](https://www.desertcart.tn/products/448029875-smd-smt-components-soldering-practice-board-electronic-project-kits-diy) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-05-06*
