This kit contains resistors and capacitors packaged in 0805, surface mount aluminum capacitors, surface mount resistors, surface mount crystal oscillators, surface mount LED lights, surface mount diodes, and surface mount chips packaged in SOP14, SOP20, TQFP44, etc. It has 12 surface mount test areas with soldering difficulty ranging from low to high, and each group can be independently tested. It has short-circuit and virtual soldering test functions, which can determine whether the soldering is successful based on the display of the LED light. There are 12 surface mount test areas, with a total of 300 surface mount soldered components. By soldering, the soldering ability, speed, and circuit maintenance ability of various surface mount components can be improved, meeting the difficulty of competitions. It also has a self checking function, and when powered on, the soldering results and the occurrence of soldering errors can be seen.

This kit is designed by our company's electronic engineers who have participated in competition judges for many years, specifically for vocational electronic product assembly and debugging competitions, electronic students, and electronic enthusiasts to improve the soldering of surface mount components.
