The LED unit board kit mainly includes a mask, bottom case, positioning holes and mounting screws, etc. However, the LED unit board kit must be moisture-proof, waterproof and UV-proof, and the quality of the kit affects the flatness, contrast and use of the display. life. So how to choose a good LED unit board, let's let you know about it.


First: choose according to the PCB board of the module


The technical requirements of the LED unit board module on the PCB board are much higher than other parts.


Not only that, the potting glue of the LED unit board module is also a very important link that affects the function of the display module. It can affect the application performance of the LED unit board module. However, in the application process, there are many factors that affect the quality of the module PC board by the external environment, such as the size of the through hole, the thickness of the coating, and the material of the substrate. Now, the PCB board of the LED unit board module is generally composed of a base material and a metal coating to form an integrated circuit.

Second: refer to the kit of the module


The LED unit board module kit is the core structural component of the outdoor surface mount module, which can protect the lamp beads, the unit board and the core elements of the entire screen. Therefore, the user should consider the application environment of the PCB board of the module in the process of selecting the LED unit board. In addition, due to the difference of various materials at present, the expansion coefficient of the LED unit board lamp beads is different from the external environmental factors, and the gold wire connection is easily broken, but the result will lead to dead lights and flashing lights. Therefore, The lamp beads of the LED unit board module are especially important.


Third: choose according to the lamp beads of the module


The selection of raw materials and packaging technology of the LED unit board is particularly important, which directly determines the quality of the LED unit board product quality. It can be seen that users should pay attention to the above selection methods in the process of purchasing a reliable LED unit board.
