## Overview

This DIY SMD/SMT soldering practice board kit from Dingdong Store offers a compact, 12x7 cm platform to develop precision soldering skills using real electronic components. Powered by DC 5V, it features a running water lamp that visually confirms successful soldering. Perfect for professionals, hobbyists, and educators, it includes a clearly labeled PCB and comprehensive instructions, supported by dedicated customer service to ensure a smooth learning experience.

## 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: About Went Blind - Great little kit for practicing SMD soldering. Be ready with tweezers and jewelers loop headset. Flux and a small paintbrush are your friend. Not for first-time solder'ers.
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!

## 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.

### ⭐⭐⭐⭐⭐ About Went Blind
*by R***T on 5 March 2026*

### ⭐⭐⭐⭐⭐ High qualitypractice
*by K***N on 10 June 2024*

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.

### ⭐⭐ Instructions are a joke
*by J***H on 7 June 2023*

The instructions don't make an ounce of sense. I'm not even convinced the manual I got is for this kit...but I can't decipher enough to know it isn't.
