3V-12V PCB Circuit Board SMD Components for Welding Machine
Feature:
l The PCB board has a reasonable design and can be put in a pocket.
l The left and right 3 columns of components are used to practice soldering, and each column has test points.
l There is a ruler on the back of the circuit for easy measurement of components. There are examples of PCB wires to facilitate PCB design and use.
l All commonly used SMD components are used.
l The circular circuit in the middle is the water lamp circuit, which is composed of 4017, NE555, and light-emitting diodes. It can work after the welding is correct.
