DIY Christmas Tree 3D Xmas Soldering Practice Electronic Assemble Kit Project for Kids Teens 3 Colors Flashing LED PCB Solder
The small Christmas tree kit is composed of two light boards and a light board base to form a tree like shape. The LEDs on the two light boards flash alternately like water on the tree shaped board, which has a very beautiful effect. This kit can exercise the welding ability very well. It is a good choice to appreciate it and give it as a gift.
Features:
1. Working voltage: 4.5-5v (DC voltage)
2. Finished Dimensions: 60mm length x 60mm width x 136mm heightabout 12.5cm
3. The flash Christmas board need to solder by yourself.

Common problem
1. First of all, it's not the quality problem of the lamp if the lamp doesn't light after welding. You can test the LED with
button battery 2032 before welding. The test voltage is 3.0-3.5v, the current is about 20mA, and it should not be greater than 3.5V. You can't use dry battery, mobile phone battery, rechargeable battery, etc. After 50 sets of welding tests, the causes of lamp failure include static damage to led by electric soldering iron, welding damage to LED and bending pin damage to LED. Generally, if it is smooth, two more lamps do not light up, and we can replace them with two or three more lamps we give. Beginners can buy more spare in the store! thank you!
2. The recommended welding sequence is to weld the components of the base plate first, and then weld the resistance of a and B lamp plates - led - triode - electrolytic capacitor in turn. The LED on the top of board a shall be welded after assembly.
3. The resistance value shall correspond to that marked on the board one by one.
4. Pay attention to the positive and negative poles of the LED lamp. The long pin is the positive pole. The welding time of the LED lamp shall be as short as possible to avoid burning the LED.
5. Insert the triode according to the shape on the board.
6. Pay attention to the positive and negative poles of electrolytic capacitor, and the long pin is the positive pole.
7. After welding a lamp board, first connect the 5V power supply to the positive and negative electrodes under the board, test and check whether there is any lamp that does not light up. If a lamp does not light up, check the welding faulty welding and lamp damage, and then replace it. If the six lamps in parallel with the schematic diagram do not light up, check the welding short circuit of the six lamps. If they do not light up, check the welding short circuit of the whole circuit Faulty welding, poor power contact and other problems.
8. When assembling the lamp plate and the base plate, pay attention to the positive and negative poles of the lamp plate and the base plate one by one, which is difficult to remove if it is wrong.
