This 4-layer FR4 printed circuit board is specially engineered for 5G base station and communication server equipment. Constructed with 3mm thick high TG FR4 substrate, 2OZ heavy copper foil and minimum 0.3mm finished hole size, the PCB delivers excellent current carrying capacity, mechanical rigidity and stable electrical performance for long-term continuous operation of outdoor and indoor 5G communication hardware.
Thick 2OZ copper design satisfies high-power circuit transmission demand; the 0.3mm minimum drill hole meets dense component layout requirements. We support customized impedance control, anti-tarnish surface treatments including ENIG, OSP and immersion silver. All production follows strict IPC-A-600 & IPC-2221 standards, compliant with RoHS and UL certification requirements. Widely adopted in 5G remote radio units (RRU), baseband processing boards, power amplifier modules and communication server control boards. Prototype sampling and mass volume orders are both acceptable.
