Whether it is a star concert, indoor 3D special effects, or some office buildings above the advertising screen, the more clear and brilliant screen, the more stringent the requirements of the PCB. Lighting PCB production process is not very complex, but in some processes above but also very difficult, especially some HDI type of light board, the production difficulty is greater than the general PCB difficulty.

LED display with PCB inner and outer wiring density is extremely high, generally the minimum line width line spacing for the inner and outer lines of 4mil, some of the ultra-dense spacing LED display inner and outer minimum line width line spacing of 3.5mil. COB LED display design features determine the minimum line width line spacing requirements of 2.5mil, corresponding to the outer layer of copper thickness of the recommended 10Z, in order to ensure that the yield of the dense line. This requires precise control of line width and spacing in the production process to ensure the normal function of the display and high quality display.
Sanxis Tech has invested a lot of time and resources in the research and production of PCB for LED screen light boards, constantly optimising the production process and improving the process capability of the light boards.
