High-speed PCB layout governed by signal-integrity and timing margins.
Qmax Systems engineers high-speed digital boards where signal integrity, timing margin, and power delivery decide whether the board boots. DDR4/DDR5 routing, PCIe Gen3/Gen4 channel design, and 10/25G SerDes lanes are validated through pre- and post-layout SI/PI simulation in Cadence Sigrity and Ansys SIwave. Typical applications: server compute, networking line cards, and FPGA data-acquisition boards.

- Resonant, LLC, CLLC, and Class-D topologies.
High Power & Reliability
- Battery systems (BMS), chargers, inverters, HV/HC PCB design.
- Thermal simulation, derating, and reliability analysis.
Pre- and post-layout signal & power integrity analysis before a single board is fabricated.
Qmax Systems performs pre- and post-layout signal and power integrity analysis before a single board is fabricated, using Cadence Sigrity and Ansys SIwave. Transmission-line simulation, eye-diagram analysis, IBIS-based driver/receiver modeling, and PDN impedance analysis are offered standalone or integrated into any PCB layout engagement. Typical applications: DDR5, PCIe Gen4/5, and high-speed SerDes channels.
Simulation & Modeling
- Transmission line simulation, eye diagram, and IBIS-based driver/receiver modeling.
PDN & Decoupling
- Power delivery network impedance analysis and decoupling capacitor optimization.
A PCB design is only as reliable as its component library.
Over three decades, Qmax Systems has built a verified, well-documented library of schematic symbols, PCB footprints, and 3D STEP models across 30,000+ components. Every part is validated against manufacturer datasheets and IPC-7351 land-pattern standards. Typical applications: new component creation, library migration, and footprint qualification for high-density designs.
Library Standards
- Schematic symbols, PCB footprints, and 3D STEP models validated to IPC-7351.
Lifecycle Management
- Footprint accuracy maintained through component revisions, reducing manufacturing errors.
An independent PCB design review - identifying risks before you release to fabrication.
Qmax Systems delivers an independent PCB design review that identifies risks before release to fabrication. The review audits your existing layout against a structured checklist covering layer stack-up, placement, routing, silkscreen, drill notes, and documentation, then delivers a formal technical report with prioritized SI, DFM, thermal, and compliance findings. Typical applications: pre-fab sign-off, second-opinion reviews, and inherited-design risk assessment.
Review Coverage
- Stack-up, placement, routing, silkscreen, drill notes, and documentation completeness.
Deliverable
- Formal technical report with prioritized SI, DFM, thermal, and compliance findings.
PCB Design Across Industries
Medical & Healthcare
Qmax Systems designs PCBs for medical devices, diagnostics, imaging, and life-critical patient systems. From wearable monitors to surgical and implantable equipment, these layouts meet IPC-6012 Class 3, ISO 13485 design controls, and strict isolation, creepage, and clearance rules of regulated healthcare environments.
Qmax Systems builds leakage-current-safe routing, reinforced isolation barriers, and long-life stack-ups for sterilization and clinical reliability.

Why Choose Qmax for PCB Design?
First-Time-Right Philosophy
Before Gerbers leave the building, Qmax Systems runs DRC, SI/PI, and thermal simulation, setting routing constraints up front so the first fabricated board behaves as designed - no costly re-spins.
30,000+ Verified Component Libraries
Qmax Systems validates every symbol, footprint, and 3D model against manufacturer datasheets across 30,000+ verified components — eliminating pad mismatches and assembly surprises.
Global Compliance Expertise
CE, FCC, UL, IPC, and MIL-STD-461 are designed in at the layout stage, because Qmax Systems treats compliance as a confirmation, not a gamble - via an EMC-by-design approach.
Production & Documentation Readiness
Every design ships with 100% DFM-verified files to IPC-2221/2226; Qmax Systems delivers complete IPC-2581/ODB++ packages, controlled-impedance drill tables, and worst-case tolerance analysis.
Fabrication Partner Network
Qmax Systems works with qualified fabs and assembly houses with traceable sourcing, plus direct liaison to lock stackup and materials (FR-4, Megtron 6, Rogers 4350B) and flag single-source parts early.
Strict IP Protection
A mutual NDA is signed from day one, and Qmax Systems stores all design files in an access-controlled vault, never on shared drives: Customers own all IP at every milestone.
