  • Welding skills:When soldering the IC chip, carefully place the chip on the PCB with tweezers to align it with the pad, and ensure that the chip is placed in the correct direction. Hold the chip with a tool, dip the tip of the soldering iron with a small amount of solder, and solder the pins at two diagonal positions to fix the chip and not move it.
  • Product parameters:PCB size:60x25mm. input voltage:3-6v.
  • Great School Science Project: It is widely used in schools to help students learn basic mechanical and electronic skills.
