Global Compliance

Pre-designed for EMI/EMC, CE, FCC, and UL - reducing certification rework and accelerating time to global market.

Lifecycle Support

End-to-end engagement from concept and proof-of-concept through volume production, ECO management, and long-term supply continuity.

Why Choose Qmax for Digital Hardware Design?

Transparent & Supervised Process

You see every milestone, design review, and risk register as it happens. Qmax Systems program managers run a weekly cadence with traceable deliverables, on-time builds, and zero hidden surprises at handover.

Digital Platforms Built from Scratch

Every digital hardware program starts with R&D and a proof-of-concept build to retire architectural risk early. We confirm feasibility, lock the BoM, validate stackup and high-speed channel margin, and prove critical assumptions before a single production layer is committed.

Smooth Hardware-Software Integration

We select SoCs, FPGAs, memories, and toolchains that fit your existing platform rather than forcing a re-platform. The result is firmware that brings up cleanly, board support packages that drop into your OS, and lower long-term maintenance cost.

Expert Digital Hardware Engineers

Qmax Systems digital hardware engineers average 12+ years across AI infrastructure, telecom and O-RAN, embedded edge computing, defense electronics, and industrial IoT. Only senior engineers touch your design - no junior hand-offs, no learning on your timeline.

Frequently Asked Questions

What high-speed design standards does Qmax Systems support?
Qmax Systems specializes in the latest high-speed communication standards, including PCIe Gen 5/6, DDR5, and 112G SerDes. The Qmax Systems engineering team utilizes advanced simulation tools - full-wave EM, IBIS-AMI channel modeling, and target-impedance methodologies - to ensure signal integrity (SI) and power integrity (PI) for data rates exceeding 100 Gbps.
Can Qmax Systems design custom hardware for AI and Deep Learning?
Yes. Qmax Systems develops High-Density AI GPU Compute Servers tailored for massive parallel processing workloads. Our designs focus on robust Power Delivery Networks (PDN) and advanced thermal management strategies required to sustain the performance of high-TDP NVIDIA and AMD GPU clusters used in AI training and inference.
Does Qmax Systems provide O-RAN and 5G infrastructure hardware?
Absolutely. Qmax Systems is active in the O-RAN ecosystem, designing Distributed Units (DU) and specialized Network Interface Cards (NIC). We help telecom providers and private network operators deploy scalable, open-architecture hardware for 4G and 5G rollouts.
What processor architectures does Qmax Systems work with for server motherboards?
Qmax Systems' expertise spans the leading x86 and ARM-based enterprise architectures, including Intel Xeon, AMD EPYC, and Ampere Altra CPUs. We design custom server motherboards and Single Board Computers (SBCs) in OCP-compliant, 1U/2U rackmount, and rugged industrial form factors that meet specific environmental and compliance requirements.
Does Qmax Systems handle complex, high-layer count PCB designs?
Yes. Qmax Systems engineers are experienced in high-density interconnect (HDI) technology, regularly managing 20+ layer PCB stacks with blind and buried microvias for DDR5, PCIe Gen6, and 112G SerDes routing. We ensure every design is optimized for DFM (Design for Manufacturing) and DFT (Design for Test) to streamline the transition to mass production.
What is included in the 1-hour complimentary consulting session?
During this session, you will speak directly with a Senior Hardware Architect from Qmax Systems. We can review your block diagrams, discuss thermal or signal integrity challenges, provide high-level architecture validation, or help refine your hardware roadmap to reduce time-to-market. We can sign an NDA if required.
How does Qmax Systems protect customer design data and intellectual property?
Qmax Systems treats every engagement under strict IP protection: NDAs signed before any technical discussion, dedicated secure project workspaces, role-based access control to design files, and customer-owned IP at every milestone - schematics, layouts, BoMs, and firmware. Qmax Systems engineers never reuse or repurpose customer IP across other client engagements.
How does Qmax Systems ensure signal integrity and power integrity in high-speed digital designs?
Qmax Systems' SI/PI methodology combines full-wave 3D electromagnetic simulation, IBIS-AMI channel modeling for DDR5 and SerDes interfaces, and target-impedance PDN design backed by simulation-driven decoupling. Every high-speed design - DDR5, PCIe Gen5/Gen6, 100GbE, 112G SerDes - is validated against compliance margin before fabrication, eliminating costly re-spins.
