It was successful 5 minutes into the project as I opened the package and started looking at the miniscule bits and figuring out how to determine where they went on the board. The package included instructions, but they were in Chinese for the most part. That being said, the PCB is marked with identifiers that can be referenced against the parts list and you can figure out what needs to go where. The only part I was confused by was the fact that you are supplied with some extra parts for practice. I recommend using a portable device and Google Lens/Google translate to translate the Chinese instructions. I did get a pretty good laugh out of the translation for the second row of components that were included JUST for practice and were not necessary for actually making the LED circuit work: "The following components are the combat equipment for practice." Overall this is a really good kit for the price, the quality is great and robust, it's not going to be something that falls apart while you're trying to put it together. I'd say this is more intermediate level than beginner though. Understanding how to apply small amounts of solder and control your iron or heat gun is going to be vital for preparing the PCB for populating. If you aren't there yet, watch some youtube videos and practice just putting solder on pads and using flux to make things go smoothly. I would even buy these as gifts for electronics geeks that are curious about getting into electronics as a hobby or just want to put together a kit for fun! Review: Great For Practicing and Will Advance Your Soldering Skills - This board kit is extremely beneficial for enhancing your surface mount component soldering skills, but sadly, upon completion and a careful double-checking, the board did not function. I believe it was a resistor issue, as the components in the kit I received where not the same as the others I'v seen on YouTube. The company reached out to me offering a full refund/replacement which I found extremely honorable and greatly appreciated. My personal soldering skills have definitely improved with the use of these kits, this is my second kit. I also find these somewhat relaxing and therapeutic to build, as they require concentration. ## Features - PCB blank board Size: 80mm x 60mm - The circular circuit is the running water lamp circuit, which is composed of CD4017, NE555 and leds, which can be used to work after being welded. - Add 2pcs of QFP44 chip, double sided component layout, double welding. - High quality PCB, has clearly marked the electronics components, even beginners can easily solder successfully. - Please make sure all components in right direction and right place; and check whether pseudo and float welding, this is very important in practicing and testing. ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.1 out of 5 stars 200 Reviews | ## Product Details - **Brand:** Gikfun - **Graphics Card Description:** Dedicated - **Specific Uses For Product:** Education - **Personal computer design type:** Barebone - **Model Name:** DIY SMD SMT Welding Practice Soldering Skill Training Board NE555 CD4017 Water Flowing Led DIY Kit - **Included Components:** PCB Board, CD4017, NE555, LEDs, 2 x QFP44 Chips - **Special Feature:** Waterproof - **Connectivity Technology:** USB - **RAM Memory Technology:** DDR4 - **Display Type:** LED ## Images ![- DIY SMD SMT Welding Practice Soldering Skill Training Board NE555 CD4017 Water Flowing Led DIY Kit EK1885 - Image 1](https://m.media-amazon.com/images/I/71+ENRHVAjL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ You will learn from this kit! *by R***M on September 20, 2022* I bought this for its intended purpose: Learning how, but more importantly, practicing soldering a variety of SMD components.

Most project kits are almost (or entirely) through-hole, which is fine, but doesn't suit my purpose. Searching Amazon, I found a very small number of SMD practice boards, but only one or two let you assemble a board that actually does something - most just have dozens or hundreds of pads for attaching components, but nothing more. This Gikfun board has the best of both worlds. About half of the board consists of pads for practicing on a variety of different kinds of components and the other half forms a "water clock" where a timer and counter circuit make LEDs animate in a pattern that resembles a clock face. Using advice from many YouTube channels on how to hand solder SMD parts, I was able to assemble the functional part of the kit in about four hours. There are additional components for the non-functional part of the board that I have yet to assemble - I'll probably do them at a later time. The kit does not include anything resembling a power supply. Just two pads labeled +/- 5V. I used a 4-AA battery holder that I had lying around to send 6V into those pads, which made the entire clock come to life. Which is important because it demonstrates that I successfully assembled the kit, even though this is far from the best quality soldering job (it is, after all, my first practical SMD project!) My only complaint is that the instructions are minimal. There is one piece of paper. On one side is the schematic of the functional part of the board. On the other is a few paragraphs of Chinese (which I can't read) and a parts list, where the text is Chinese but there's enough non-Chinese text (numbers, part numbers, component ratings, etc.) that I was able to properly match up the supplied components with the parts list, the schematic and the markings on the board. I have sent a copy of this paper to a friend who reads Chinese so he can translate it. After I hear back from him, I plan on sharing that translation on my personal blog and will share a link here, if Amazon allows it. ## Frequently Bought Together - Gikfun DIY SMD SMT Welding Practice Soldering Skill Training Board NE555 CD4017 Water Flowing Led DIY Kit EK1885 - 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.tw/products/76195817-diy-smd-smt-welding-practice-soldering-skill-training-board-ne555](https://www.desertcart.tw/products/76195817-diy-smd-smt-welding-practice-soldering-skill-training-board-ne555) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-11-05*
