How to buy LED unit board? Shenzhen Liansen Optoelectronics LED display manufacturers share the knowledge points of LED unit board purchase!
Knowledge points of LED unit board purchase:
First: Choose according to the lamp beads of the module
The material selection and packaging technology level of the lamp bead of the LED unit board is particularly important, which directly determines the quality of the LED unit board product. In addition, due to the differences in various materials at present, the expansion coefficient of the LED unit board lamp beads is different from the external environmental factors. It is easy to break the gold wire connection, but the result will lead to dead lights and flashing lights. Therefore, The lamp beads of the LED unit board module are particularly critical.
Second: 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. Nowadays, the PCB board of the stable LED unit board module is generally composed of a substrate and a metal coating to form an integrated circuit. However, in the application process, the external environment has many factors that affect the quality of the module PC board, such as the size of the through hole, the thickness of the coating, and the material of the substrate. Therefore, the user should consider the application environment of the module's PCB board when selecting the LED unit board.
Third: Refer to the kit according to the module
The LED unit board module kit is the core structure of the outdoor surface mount module, which can protect the key elements of the lamp beads, unit board and splicing the entire screen. 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.
Not only that, the potting glue of the LED unit board module is also a very important link that affects the performance of the display module. The potting glue has a degree of adhesion, corrosion, UV resistance, resistance to aging, and strong airtightness. And other characteristics can affect the application performance of the LED unit board module. It can be seen that users should pay attention to the above-mentioned selection method when purchasing a reliable LED unit board.
When you find yourself in need of About Us led pcb module, you may not know where to begin. And that's OK! Search out Demo Photoelectric Technology (Wuxi) Co., Ltd. to handle your About Us needs.
Demo Photoelectric Technology (Wuxi) Co., Ltd. will continue to bring our industry nuances of style and approaches to About Us which are consistent with our evolving aspirations.
The first machine to produce dob led pcb, the ac led modules About Us was invented in led light engine in led light engine module by led pcb board and was subsequently improved.
