Custom 4-Layer DIP LED Display PCB High-TG FR-4 & ENIG Surface Finish:
Crafted by Xingqiang PCB—a leading manufacturer since 1995 with ISO 9001 & IATF 16949 certifications—this highly customizable LED display PCB is specially engineered for DIP outdoor full-color screens and billboards. Built with 4-layer high-TG FR-4 and UL 94 V-0 flame-retardant materials, it delivers excellent thermal stability, low warpage, and long-term outdoor reliability. With precision ENIG surface treatment from automated production, it offers outstanding solderability, oxidation resistance, and stable electrical performance. Optimized for LED driving, signal transmission and power distribution, it reduces interference and ensures uniform brightness. Fully RoHS, Reach and IPC Class 2 compliant, this board supports fully tailored layer stack-up, impedance control, pad design, thickness and copper weight. Backed by strict quality control and professional OEM/ODM service, Xingqiang provides flexible custom solutions to meet diverse requirements for stage, stadium, traffic guidance and industrial display projects.

RReliable moisture barrier bags used. Even with the long ocean freight, the boards arrived in pristine condition.

ABlack boards typically absorb heat, but this multilayer board's heat resistance exceeded expectations. During localized high-temperature soldering with a hot air gun, the surrounding black solder paste did not change color or bubble, and the boundary between the solder pads and the black solder paste remained neat with no solder paste creeping.

OAppreciate the interleaving tissue paper between each matte black board. It effectively prevented friction scratches on the delicate surface during international transit.
