We manufacture PCBs from single-layer to 56 layers, supporting everything from simple consumer electronics to ultra-dense AI server backplanes.
| Layer Count | Typical Applications |
|---|---|
| 1–4 layers | Consumer electronics, IoT sensors, simple control boards |
| 6–12 layers | Industrial controllers, automotive sub-systems, communication modules |
| 14–24 layers | AI inference cards, ADAS ECUs, high-speed networking |
| 26–56 layers | AI server mainboards, data center switching, high-density computing |
Our manufacturing capabilities go well beyond standard specs:
Not every application can use FR-4. Our manufacturing service covers a comprehensive range of PCB materials:
Our integrated 5 IPI smart manufacturing bases and 100+ factory cloud alliance ensure consistent quality at every step.
Before a single drill hits the material, our engineering team runs a thorough Design for Manufacturability (DFM) check:
Every board passes through our multi-stage quality gate before shipping:
| Test | Standard |
|---|---|
| Automated Optical Inspection (AOI) | IPC-A-600 Class 2/3 |
| Electrical Testing (Flying probe / E-Test) | IPC-9252 |
| Impedance Test (TDR) | ±5% tolerance |
| Cross-section analysis | IPC-6012 |
| Final visual inspection | IPC-A-600 |
Our 98.5% EMC pass rate and CMA/CNAS laboratory certifications back this up with independent verification.
Need boards fast? Our quick-turn service delivers:
We maintain dedicated prototype lines with independent tooling and scheduling — so rush orders don't get caught behind production queues.
Our PCB manufacturing service powers critical applications across multiple industries:
AI & Edge Computing High-density multilayer boards for GPU compute cards, edge inference modules, AI server backplanes, and data center networking equipment. We understand the signal integrity and thermal demands of today's AI hardware — including 112Gbps SerDes routing and back-drilling.
Automotive Electronics AEC-Q100 qualified manufacturing for ADAS systems, EV battery management, electric drive control units, and in-vehicle infotainment. We meet IATF 16949 quality management requirements for automotive-grade reliability.
Medical Devices ISO 13485 certified PCB manufacturing for patient-facing medical equipment, imaging systems, and diagnostic devices. We comply with IEC 60601 and FDA QSR 820 standards, with full traceability and controlled documentation.
Industrial Control & Automation Ruggedized PCBs for PLCs, motor drives, industrial IoT gateways, and robotic controllers. Rated for wide temperature ranges and harsh electromagnetic environments.
Energy & Power Electronics Heavy copper PCBs (up to 20oz) for power converters, energy storage inverters, smart grid controllers, and solar/wind power management systems.
We were building HDI, Rogers, and rigid-flex boards before most of today's competitors existed. That depth of experience means fewer surprises and faster solutions when your design pushes the limits.
Our design engineers and manufacturing teams work under the same roof. When DFM issues arise, they're resolved in hours — not weeks of back-and-forth email.
Flexible capacity for prototype runs, small batches, and high-volume production. Scale up without switching suppliers.
21,800+ customers across North America, Europe, and Asia trust us with their most demanding PCB requirements. From startups to Fortune 500 companies, we deliver to the same uncompromising standard.
