On the bottom layer, there are 9 types of components, with a total of 90 components, 255 solder joints, and 14 test points, which can be used for initial component identification and soldering practice. On the top layer, there are 13 categories of components, with a total of 150 components, 348 solder joints, 21 test points, and 10 pads, which can be used for soldering examinations. The soldering quality can be directly reflected by the lighting conditions of 31 LEDs. The circuit is novel and highly interesting, with a complete range of component types. It uses a double - sided fiberglass tin - sprayed board. It is another masterpiece following the Juling 1801 SMT soldering practice board and can be used for SMT soldering practice, training, examinations, competitions, etc. A WORD - format mock test paper is provided, which is convenient for everyone to modify flexibly. This kit includes ultra - small components such as 0201 and 0402, as well as SOT323 anti - electrostatic field - effect transistors, greatly increasing the soldering difficulty.
