5X SMD Component Welding Practice Board DIY Kit Skill Training Board Led Transistor Set Practice

5X SMD Component Welding Practice Board DIY Kit Skill Training Board Led Transistor Set Practice Description

[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 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.
[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 the board makes it easy to assemble. And you can refer the marks PCB board to soldering each component.
Precautions for welding:SMD components are relatively small, be careful not to lose.

Different batches have different silk screen batch numbers, which does not affect use.
