TJ-56-617 SMD component welding practice board kit is a special welding practice board for the new electronic product assembly skills competition, which is powerful and practical. The PCB board is made of high-quality glass fiber board, and the whole process of the large factory is sprayed with tin. The quality is excellent, and the design is optimized for practical training. This practice board refers to the package type of SMD components in the National Vocational College Electronic Product Assembly and Debug Skills Competition. It is used to improve the welding skills of students majoring in electronics and electronics enthusiasts.

Features:

Training - There are 132 components and 530 solder joints, which is convenient for training speed.

Comprehensiveness - The circuit has 19 types of commonly used SMD components and can be familiar with using more components.

Savings - Can be used repeatedly after desoldering to increase the utilization rate.

Flexibility - Each component has a number and no parameters, so the parameters can be adjusted flexibly.
