16-Layer 3.6mm Thick PCB

A 16-layer thick-board PCB built on S1000-2M FR-4 substrate at 3.6±0.36mm finished thickness, designed for high-current and high-voltage carrier boards. The thick stackup provides enhanced mechanical rigidity and improved dielectric strength between power planes, allowing the board to handle high inrush currents and sustained thermal loads. Sequential lamination across 16 copper layers supports complex power distribution networks alongside dense signal routing in backplane and motherboard applications. Typical use cases include high-power industrial drives, base-station power supplies, telecom rectifier shelves, and energy-storage management boards. The substantial board thickness also provides better connector retention force and reduces warpage during reflow of large heavy-pin assemblies. Manufacturing requires extended drilling cycles, controlled lamination pressure, and careful copper balance to prevent bow and twist on the finished panel.
