Features:

This kit is used to practice soldering patch components and has the function of a water light. The practice areas on the left and right sides can be used to practice hands and master the method of welding the chip components. The acceptance area in the middle part is used to test the proficiency of the welding. It can be observed whether the welding is finished and complete, and whether the welding has complete water flow. The light shows the effect, or there are individual problems to score and understand the ability to solder the patch components yourself.

Module features:

1, PCB board design is reasonable, the size is the same as the size of the ID card, can be installed in the pocket.

2, the use of commonly used patch components.

3, the left and right two columns of components are used to practice welding, each column with test points.

4. The middle circular circuit is a water light circuit, which is composed of 4017, NE555 and light-emitting diodes.

Welding tips :

1. It is best to use a pointed or cutter head for the soldering iron. The solder is selected to be thinner, about 0.3-0.6mm. Bring your own or buy a tweezers to facilitate the welding of the clip components.

2, first weld the part of the practice area on both sides, used to practice hands, from large to small welding, 0402 is too small, you can choose to give up welding. Then in the middle of the acceptance zone welding, the components of the acceptance zone should correspond to the identification on the board, the resistance value, the LED positive and negative, and the chip direction. The mark 102=1K, the mark 104=100K, the LED faces up, the side with the green dot is the negative pole, the corner of the chip has a dot or the side with the horizontal line corresponds to the side with the notch on the board.

3, the general method of soldering chip components is to first put solder on a pad, and then clamp the component with tweezers, for the positive and negative electrodes, while melting the solder of the pad while placing the component, so that the pin contacts Solder the solder and place it in the position. You can remove the soldering iron, cool it, remove the dice, and then solder another pin. The same is true for chips.

Package include:

1 * CD4017 patch component soldering practice board
