LARGE FORMAT • 112G READY
Extra-large backplanes up to 1100 × 500 mm with 24–50 layers, low-loss laminates, ±5% impedance, and CNC backdrill keep data center and telecom fabrics reliable at 112G.
APTPCB specializes in backplane PCB manufacturing for high-layer-count, high-speed interconnect systems where registration accuracy, impedance consistency, and mechanical stability are critical. We support large-format structures and complex stackups designed for predictable signal performance and dependable connector interfaces—helping customers build scalable backplane architectures for servers, telecom, and modular systems.
Backplane assembly and testing at APTPCB includes connector integration workflows, inspection, and validation aligned to system-level reliability. By managing fabrication and assembly as a unified deliverable, we help customers reduce integration risk, improve deployment stability, and maintain consistent performance across production runs.

Innovation Roadmap
Emerging technologies shaping the future of manufacturing, signal integrity, and system integration.
01
Short-reach optical engines move onto the backplane, demanding hybrid fiber and low-loss routing in the same laminate stack.
02
Semi-additive copper builds unlock finer stripline density so 224G+ lanes fit without growing the panel outline.
03
Embedded cold plates and dielectric liquid loops migrate onto the backplane frame to dissipate accelerator heat directly.
04
Real-time digital twins pair AI analytics with channel telemetry to predict SI drift and retune fabrics before hardware ships.
Low-loss materials, backdrill, and large panels add cost—apply premium features only where needed. Reuse stackups, drill sets, and panel sizes across chassis to minimize NRE. Provide insertion loss, connector types, and panel constraints so we can scope the leanest solution.
