Electronic Product Design
One engineering partner from the first sketch to the production line — hardware, firmware, and the manufacturing to back it up.
What is electronic product design?
Electronic product design is the engineering process of turning a product idea into a manufacturable electronic device — covering requirements, system architecture, schematic and PCB design, firmware, prototyping, and validation. We handle every stage ourselves and carry the design through to production, so one team owns the result instead of three.
One team from concept to production
Most product ideas stall in the handoffs. A design firm draws the schematics, a separate fab builds the boards, an assembler populates them, and when something does not work, everyone points at someone else. We removed those seams. Engineering and manufacturing sit in the same building in Addison, Illinois, so the people who designed your product are the people who build it.
That changes how the work feels. Design-for-manufacturing feedback lands while the layout is still open. A prototype tweak is a walk down the hall, not a three-week vendor cycle. And when it is time to scale, we are not introducing a new manufacturer to your design — we already know it intimately.
Engineered to be built, not just to work
A clever circuit that cannot be assembled affordably is not a finished design. We design for the realities of production from the start: part availability and second sources, panelization, test access, thermal behavior, and the tolerances your assembly process can hold.
The result is a design package that moves to the production floor cleanly — manufacturing-ready files, a vetted BOM, and documentation complete enough that the build is predictable the first time.
Design firm vs. freelancer vs. hiring in-house: which is right?
There are three realistic ways to get an electronic product designed: engage a design firm, contract a freelance engineer, or build your own team. The right choice depends on how many disciplines the product touches, how fast it has to ship, and what happens after it ships.
| Design & engineering firm | Freelance engineer | In-house team | |
|---|---|---|---|
| Best for | Complete products that touch several disciplines — hardware, firmware, mechanical | Small, well-bounded tasks inside a single discipline | Companies with a continuous, multi-year pipeline of design work |
| Disciplines covered | A full bench: circuit design, PCB layout, firmware, mechanical | One person's specialty — the rest is yours to source and coordinate | Whatever you hire for — each discipline is a separate salary |
| Speed & continuity | A team absorbs workload spikes and specialist gaps mid-project | A single point of failure; the schedule follows one calendar | Months of recruiting before design work can even start |
| Cost structure | Scoped project pricing or T&M — no payroll between projects | Lowest hourly rate, but management and integration fall on you | Salaries and overhead continue whether or not there is design work |
| Path to production | At AEE, the design moves straight onto our own production floor | Ends at design files — fabrication and assembly are yours to arrange | Ends at design files — you still need a manufacturing partner |
What full product design covers
From first meeting to production release
- 01
Discover
We define requirements, constraints, and success criteria, then assess feasibility and risk before committing to an architecture.
- 02
Architect
We choose the technology — processor, connectivity, power, and sensing — and lay out a system architecture that balances cost, performance, and manufacturability.
- 03
Design
Schematic capture, PCB layout, and firmware proceed in step, with internal design reviews at each milestone.
- 04
Validate
We build prototypes, bring them up, and run engineering and design validation tests (EVT/DVT) against the original requirements.
- 05
Produce
We hand the design to our own production floor, qualify it for volume (PVT), and scale up — no new supplier to re-qualify.
What you own at the end
The engagement at a glance
How much does electronic product design cost?
Engineering cost scales with complexity — the number of boards, the difficulty of the firmware, and how much regulatory testing the product needs. The ranges below are typical engineering investments to reach a production-ready design; they exclude tooling and per-unit manufacturing.
| Type of product | Typical engineering investment | What drives the number |
|---|---|---|
| Single-board device, modest firmware | $15,000 – $50,000 | One PCB, standard interfaces, limited certification |
| Connected or multi-board product | $50,000 – $150,000 | Multiple boards, wireless, custom firmware, app or cloud links |
| Complex or regulated system | $150,000 – $500,000+ | Medical/industrial compliance, safety testing, multiple iterations |
Directional ranges for engineering only. We scope and quote each project precisely once requirements are defined, and recommend fixed-price or time-and-materials based on its risk profile.
Electronic Product Design FAQs
A typical project runs through six stages: (1) requirements and feasibility, (2) system architecture and technology selection, (3) hardware and PCB design, (4) firmware and integration, (5) prototyping and design validation testing (DVT), and (6) the transition to production. Each stage ends with a review so problems are caught when they are still cheap to fix.
It depends heavily on complexity. A simple single-board product might be tens of thousands of dollars in engineering, while a connected, multi-board system with custom firmware and regulatory testing can run into the hundreds of thousands. We scope each project up front and recommend the engagement model — fixed-price or time-and-materials — that fits its risk profile.
A clear problem statement is enough to start. Clients arrive with everything from a napkin sketch to a detailed specification — or a half-finished design from another team. The discovery stage exists to turn whatever you have into written requirements and success criteria, so gaps are found on paper instead of in prototype hardware.
Most full product designs take roughly four to twelve months from kickoff to production-ready, depending on complexity, certification requirements, and how many prototype iterations are needed. We define a milestone schedule at the start and keep you visible to progress throughout, rather than disappearing until a "big reveal."
You do. At the end of the engagement you own the schematics, PCB layout, firmware source, documentation, and prototypes. We design your product to be yours — including the freedom to manufacture it wherever you choose, although most clients keep building with us.
