Solutions · Engineering & Design

From schematic to fabrication-ready files.

Schematic capture, multi-layer PCB layout, high-speed digital design, thermal and power management, and DFM review. A full engineering extension of your team — or a standalone layout service when your schematic is ready and you just need the layout.

PCB design and engineering covers schematic capture, multi-layer layout, signal and power integrity, thermal work, and DFM review. RLX Solutions provides engineering from concept to fabrication-ready files, with UL and CSA certification requirements built into the design from the start.

01 — Overview

Engineering at any stage.

Some customers come with a concept and a requirements doc. Others arrive with a mature schematic and a stackup target. We meet the program wherever it is — from requirements capture and architecture through final fabrication package release — and hand off with build-ready files.

Every PCB we design is fabrication-aware. We know what the process allows, what it doesn't, and what pushes cost without improving the product. Our DFM feedback happens while the layout is in progress, not after the quote. Same for DFA — component placement decisions consider the pick-and-place envelope, stencil aperture, and test access from the first revision.

When the design is finished, it flows directly into RLX fabrication and assembly — or we release the files to your preferred manufacturer. Either way, you own the IP and the full design database.

02 — Services

Engineering capabilities.

01

Schematic Capture

Complete schematic design from requirements or block diagrams. Component selection, reference design adaptation, power-supply sizing, and interface definition.

02

Multi-Layer Layout

2-layer through 24+ layer designs. Engineered stackups, controlled impedance routing, BGA fanout, escape-routing strategy.

03

High-Speed Digital

DDR memory, SerDes, PCIe, USB 3.x, HDMI, Ethernet. Length matching, differential routing, via optimization, return-path management.

04

Power Integrity

PDN design and analysis — plane capacitance, decoupling strategy, power plane layout for low impedance across frequency.

05

Thermal Analysis

Component thermal budget, heat-spreading plane design, thermal via placement, heat sink interface. MCPCB stackup when thermal limits demand it.

06

RF & Analog

Impedance-controlled RF traces, guard banding, shielding strategy, mixed-signal layout with proper ground and return-path separation.

07

EMI / EMC Review

Pre-compliance design review — common-mode chokes, filter placement, return-path continuity, shielding strategy. Often cheaper than re-spinning after test failure.

08

Flex & Rigid-Flex

Flex geometry, bend radius design, coverlay management, stiffener placement, rigid-to-flex transition. Tested and verified before fabrication release.

09

Design Audit

Review of an existing design — DFM issues, signal integrity concerns, thermal risks, and BOM optimization. Delivered as a written report.

03 — Regulatory compliance

UL & CSA certification built into the design.

Design work that ends with a certified product — not a design-in-hand that still needs a compliance sprint.

Getting a product to market means getting it through UL or CSA. We design for compliance from the first schematic revision — creepage and clearance, component selection aligned with recognized component programs, insulation system choice, and PCB layout that conforms to the certification body's requirements for the target standard.

Our experience spans UL 508A industrial control panels, UL/CSA 60950 and 62368 information technology and audio/video equipment, UL/CSA 61010 laboratory and test equipment, UL 8750 LED equipment, and UL 1310 Class 2 power units. For each program we identify the applicable standard early, design to it, assemble the certification file alongside the product, and work directly with your chosen NRTL (UL, CSA, Intertek, TÜV) through the evaluation.

When the work is done, you have a product ready for the field. Not a schematic that surprises you at submission.

05 — How engagements work

Flexible engagement models.

Fixed-scope
Agreed-on deliverables at a fixed price — common for layout-only engagements where the schematic is complete
Time & materials
For open-ended programs where requirements evolve · weekly progress reports and controlled-scope change management
Retainer
Reserved engineering hours each month for ongoing product programs · rapid response, dedicated engineer continuity
Turnkey program
Engineering bundled with fabrication and assembly · single quote, single PO, one program manager from schematic to shipment
IP ownership
Customer owns all design files and IP · NDA signed at program start · source files delivered at every milestone
Review cadence
Weekly design review with shared display · all placement and routing decisions traceable to a requirement

Tell us what you're building.

Send requirements, a reference design, or a schematic-in-progress. We'll scope the engagement and come back with a proposal — fixed scope, T&M, or turnkey.

Frequently asked questions

What engineering services do you offer?
Schematic capture, multi-layer PCB layout, high-speed digital design, power integrity, thermal analysis, RF and analog design, EMI and EMC review, flex and rigid-flex design, DFM review, and fabrication-package release.
Which design tools do you work in?
Altium, KiCad, Eagle, OrCAD and Allegro, DipTrace, EasyEDA, and Mentor PADS, with output in Gerber and ODB++.
Can you design for UL and CSA certification?
Yes. RLX has experience with UL 508A, UL and CSA 62368, 61010, and 60950, UL 8750 for LED, and UL 1310 Class 2 power units, including recognized-component selection, creepage and clearance, and NRTL liaison.
Can I engage you for just a DFM review?
Yes. A one-off DFM, DFA, or design audit is a fixed-scope engagement. You can also engage RLX for a single layout task or a full end-to-end program.
