5G & Telecom PCB Assembly
High-frequency RF and microwave PCBA for 5G base stations, antenna modules, and telecom infrastructure. Rogers, PTFE, and hybrid materials. Precision assembly for signal-critical designs.
PCBA Manufacturing for 5G & Telecom
The global 5G rollout is driving unprecedented demand for high-frequency RF and microwave PCB assemblies. 5G base station equipment, small cells, and millimeter-wave (mmWave) antenna arrays require PCBAs built on specialized low-loss substrates (Rogers, PTFE, Taconic) with precision assembly processes that preserve signal integrity at frequencies from 6 GHz to 77 GHz and beyond.
Kingdta has extensive experience assembling high-frequency PCBAs on Rogers 4003C, Rogers 4350B, RT/Duroid 5880, and other specialty RF substrates. Our assembly processes are optimized for the thermal sensitivity of these materials, using controlled reflow profiles and nitrogen atmosphere to prevent substrate delamination and maintain dielectric properties.
Beyond base station hardware, we assemble PCBAs for the full telecom ecosystem: optical transport network (OTN) boards, network switches and routers, satellite communication terminals, and private LTE/5G enterprise systems. Our BGA assembly capability handles the high-density SoC and FPGA packages common in telecom applications.
