Engineering
Beyond Connectivity
At Qmax Systems, we view PCB Design Services not merely as an interconnect task, but as a complex multi-physics engineering challenge.
In modern electronics, the physical layout is a critical component of the circuit itself. Our engineering team specializes in first-time-right PCB design.
By prioritizing early risk identification and disciplined design methodology, we deliver production-ready PCB designs that bridge complex conceptual requirements and market-ready hardware. Whether your project involves a 30-layer HDI board or a high-power converter, our designs are optimized for reliability, compliance, and manufacturability from day one.
Signal & Power Integrity
EMI & Thermal Management
Our approach integrates Signal Integrity (SI), Power Integrity (PI), Electromagnetic Interference (EMI), and thermal management into a single, cohesive workflow. This ensures that high-speed signals maintain timing and quality while the Power Distribution Network (PDN) provides stable, noise-free energy to high-performance silicon. Failure to account for these variables often results in costly re-spins and delayed time-to-market.
Our PCB Design Specialisations
Qmax Systems provides specialized PCB design engineering across seven practice areas. Each discipline is staffed by engineers with experience, supported by well-documented component libraries built over three decades, and governed by defined processes and checklists at every design stage.
High-Speed Digital PCB Design
Modern high-speed digital designs — operating at multi-gigabit data rates — impose strict constraints on PCB trace geometry, layer stack-up, via topology, and return path continuity. Our engineers apply rigorous signal integrity discipline to DDR4/5 memory interfaces, PCIe Gen 4/5, USB 3.x, Ethernet (1G to 100G), FPGA I/O, and SoC-level designs. Controlled differential impedance, length matching, crosstalk mitigation, and via stub management are standard elements of every high-speed layout we deliver.
Learn MoreRF and Microwave PCB Design
RF and microwave PCB layout requires precision substrate material selection, microstrip and stripline impedance control, low-loss routing, and careful RF-to-digital isolation strategy. Qmax engineers are experienced in designs spanning sub-GHz ISM band through Ka-band frequencies, including antenna feed networks, LNA stages, PA matching networks, and mixed RF/digital architectures on single and multi-layer substrates including PTFE-based materials.
Learn MorePower Electronics PCB Design
Power electronics PCB layout demands precise current path management, thermal dissipation planning, and EMI containment. Our engineers are experienced in DC-DC converters, AC-DC power supplies, motor drive circuits, and high-density power modules. We apply copper weight optimization, current-carrying capacity analysis, thermal via arrays, and snubber placement discipline to ensure reliable operation under full thermal and electrical load.
Learn MoreAnalog and Mixed-Signal PCB Design
Analog and mixed-signal PCB layout is among the most demanding disciplines in electronics engineering. Noise coupling, ground plane partitioning, supply decoupling placement, shielding, and the careful physical separation of high-gain analog signal paths from switching noise sources require detailed engineering judgment at every placement and routing decision. Qmax engineers apply established analog layout principles to precision instrumentation, sensor interfaces, ADC/DAC signal chains, and mixed-signal SoC designs.
Learn MoreSI, PI Analysis
Pre- and post-layout SI/PI analysis allows design problems to be identified and corrected before a board is fabricated. Our engineers perform transmission line simulation, eye diagram analysis, IBIS-based driver/receiver modeling, power delivery network (PDN) impedance analysis, and decoupling capacitor optimization. SI/PI analysis is offered as a standalone service or as an integrated element of our PCB layout engagements.
Learn MorePCB Library Services
A PCB design is only as reliable as its component library. Over three decades of active design work, Qmax has developed a verified, well-documented component library covering schematic symbols, PCB footprints, and 3D STEP models. Library parts are validated against manufacturer datasheets and IPC-7351 land pattern standards. Our library management process ensures that footprint accuracy is maintained as component revisions occur, reducing the risk of manufacturing errors caused by incorrect or outdated pad geometries.
Learn MorePCB Design Review Services
An independent PCB design review — performed by Qmax engineers against your existing layout — is an efficient, cost-effective way to identify signal integrity risks, DFM issues, thermal concerns, and standard violations before releasing to fabrication. Our review process follows a structured checklist covering layer stack-up, placement, routing, silkscreen, drill and fabrication notes, and documentation completeness. Review findings are delivered as a formal technical report with prioritized recommendations.

Frequently asked questions.
Can you design from concept or do you need a complete schematic?
We can work at any stage. If you have a concept or block diagram, our team can help develop the schematic architecture. If you have a complete schematic, we'll review it thoroughly before layout. We also offer schematic design services for teams that need end-to-end support from concept to production files.
What PCB design tools do you use?
Our team is proficient in Altium Designer, Cadence Allegro, Mentor PADS, and OrCAD. We work with your preferred tool or can recommend the best option for your project. For SI/PI analysis, we use tools like HyperLynx, ANSYS SIwave, and Keysight ADS.
What is the typical timeline for a PCB design project?
Timeline depends on complexity. A simple 4-layer design might take 2-3 weeks, while a complex 12+ layer high-speed design could take 6-8 weeks. We provide detailed timeline estimates after our initial review and can accommodate expedited schedules when needed.
Do you sign NDAs and how do you protect our IP?
Absolutely. We sign NDAs as standard practice before any technical discussions. All project files are stored on encrypted servers with strict access controls. Your design files, schematics, and documentation remain your property throughout and after the engagement.
Do you support manufacturing and assembly?
Yes. We provide complete manufacturing support including fab-ready Gerber packages, assembly drawings, and bill of materials. We have relationships with qualified fabricators and can help you select the right manufacturing partner. We also offer design-for-manufacturing (DFM) review to catch issues before production.
What industries do you serve?
We work across industrial automation, IoT/connected devices, medical devices, telecommunications, automotive electronics, consumer products, and aerospace/defense. Our multi-domain experience means we bring relevant insights from adjacent industries to every project.
