HDI Light Board

/in /by

In today’s digital age, LED displays have become an indispensable element in the fields of information display, advertising, and event hosting. One of the key technologies that supports this visual feast is high-quality PCB boards. PCB is the “skeleton” of electronic products, while the PCB of LED displays is its “soul”.

In indoor and outdoor display screens, 2-layer or 4-layer applications are the most common. Small pitch LED display screens use more layers of circuit boards to meet the requirements of high-density signal transmission. In transparent LED display screens, technology research and development continues to advance to reduce costs and improve efficiency.

The wiring density of the inner and outer layers of the PCB for LED display screens is extremely high. Generally, the minimum line width and line spacing of the inner and outer layers is 3.5mil. The design characteristics of COB-type LED display screens determine that the minimum line width and line spacing are required to be 2.5mil, and the corresponding outer copper thickness is recommended to be 1OZ to ensure the yield of dense lines. This requires precise control of the line width and spacing during the production process to ensure the normal function and high-quality display of the display screen.

SHENZHEN BEST PCBA CO., LIMITED has invested a lot of time and energy in the research and development and production of LED screen light board PCB, continuously optimizing the production process and improving the process capability of the light board!

For some conventional transparent screens and large-pitch lamp bead PCBs, our yield rate can now reach over 90%. For small-pitch through-hole lamp boards, we can guarantee that all orders with a pitch of P1.95 or above will be delivered in one go. For HDI lamp boards, the minimum lamp bead pitch we can produce is P0.98!

Our company currently has very good leadership in all kinds of straight screens, special-shaped screens, first-order and second-order HDI light boards, with an overall yield rate of over 75%!
