For 29 years Qmax Systems has designed the digital hardware at the center of AI compute, enterprise servers, telecom infrastructure and high-bandwidth networking. Our engineers take a system from requirements and architecture through schematic design, signal and power integrity simulation, multi-layer PCB layout, thermal and mechanical co-design, board bring-up and compliance, to a production-ready release package.
We work where signaling physics decides whether a board functions at all — DDR5 and LPDDR5X memory subsystems, PCIe Gen5 and Gen6, 112G SerDes channels, and PCIe carried over an optical fabric. On those interfaces, routing rules are derived from simulation before the first net is placed, not corrected after the board comes back.
Every program is owned by senior engineers from architecture through to manufacturing handover, so there is one accountable team rather than a chain of vendors. You own 100% of the resulting intellectual property at every milestone.
System architecture, silicon selection, power tree and target BoM
Capture, library work and component lifecycle engineering
Pre- and post-layout analysis that sets the routing constraints
Multi-layer and HDI layout to controlled impedance targets
Air, conduction and liquid-cooled paths designed with the board
Power sequencing, debug, link characterization and DVT
EMI/EMC and safety addressed during design, not after it
DFM, DFA and DFT release package and test jig development
Disaggregated PCIe resource chassis, GPU pooling platforms, and the optical fabric hardware that connects them across the rack.
Multi-socket x86 and ARM server motherboards, single-board computers, and the platform management hardware around them.
Carrier-grade line cards, switch fabrics, network interface cards and Open RAN distributed units for operator and hyperscale networks.
Custom FPGA platforms and accelerator cards where the workload needs deterministic latency or hardware offload.
NVMe backplanes and composable storage hardware sitting on the same fabric as the compute that consumes it.
Compact, power-constrained compute platforms running inference and control outside the data center.

The Rugged Android Digital Signage Player is a fanless, wall-mountable media appliance powered by the Rockchip RK3566 SoC. It renders live HDMI video alongside managed signage content in picture-in-picture on 4K displays. Housed in an IP54-rated aluminum enclosure, it supports PoE and fully operational OTA updates.
View case studyThe Industrial I/O Controller is a high-density digital I/O card supporting 240 discrete DIO channels, built around five synchronized automotive-grade microcontrollers. Each channel is CAN FD-configurable from a PC without reprogramming firmware. It integrates analog and pressure/switch inputs, status indicators, and cascading capability to scale I/O count for larger assemblies.
View case studyThe OBD-II Diagnostics Device is a rugged, handheld tool for automotive service environments. It reads VIN, mileage, and Diagnostic Trouble Codes in real time via embedded Linux, Wi-Fi, BLE, LTE and GPS. It auto-detects vehicle protocols using the STN2120 IC and meets FCC, RoHS, and CP65 compliance.
View case studyA GNSS and 1PPS-synchronized single board computer serving as a data base station's compute core, built around an Ampere Altra Q64-26 processor with an ASPEED AST2600 BMC. A Broadcom BCM57504 network processor drives four 25G SFP28 links, while onboard GNSS/OCXO timing synchronizes the radio network across a 16-layer, 4,200-component board.
Qmax Systems has been designing digital hardware since 1997, pairing engineers with decades of system-level insight against current high-frequency practice across PCIe Gen6, CXL and 112G PAM4. Our digital hardware engineers average 12+ years across AI infrastructure, telecom and O-RAN, embedded edge computing and industrial systems.
Fragmented delivery models create handoffs where signal integrity and thermal problems hide. Qmax houses hardware architects, PCB layout designers, SI/PI analysts, mechanical engineers and firmware developers in one delivery center, working the same program in real time rather than passing files between vendors.
Pre- and post-layout signal and power integrity analysis in Cadence Sigrity and Ansys SIwave and HFSS, followed by physical validation in our own lab on high-bandwidth oscilloscopes, spectrum analyzers, thermal cameras and temperature cycling chambers.
Complex digital hardware punishes trial and error. Qmax works to an internal framework of more than 100 schematic verification checks, component derating rules and power-sequencing gates, refined across 29 years of production programs and applied before a netlist is locked.
We carry engineering practice across industries. Low-noise techniques from medical instrumentation protect sensitive buses on dense digital boards; environmental and reliability discipline from aerospace and industrial programs hardens compute hardware; and DFM practice from volume production keeps yields predictable at scale.
EMI/EMC, safety and environmental requirements enter the design as architecture constraints - isolation, clearances, filtering, return paths and shielding - so that certification confirms what the design already achieves. Qmax operates ISO 9001 and ISO 13485 certified quality systems.
