SMT SMD Electronic Component Welding Practice Board PCB Soldering DIY

SMT SMD Electronic Component Welding Practice Board PCB Soldering DIY Kit Skill Training Both Sides - Board size: 48 * 60mm - Board thickness: 1.6mm - Material of the board: international standard plates, the pads all are tinned, have a high-intensity to Fireproof and Support beat. It can be disassembled repeatedly. - Weight: 15g - PCB board design is reasonable, no flash, size 48 * 60MM, fits in your pocket. - All the are patch element are commonly used. - The 3 lines on the left and the right are used to practice welding, each column have test points. - The circuit in the center is a circular lamp circuit, linked with the CD4017, NE555, light-emitting diodes, power can work after welding is correct. - The back side of the board can be used, too. we also provide the back components. - The double-sided SMT practice, the board occupancy rate is more cost-effective. - The circuit voltage is 3-12V - The element list shows that there are 10 major categories, a total of 102 pieces element. and there is provided with corresponding test points. More details you can refer to instructions.
