Electronic product design in Illinois
A full electronics engineering bench with its own production floor — based in Addison, working with product companies across the state.
Absolute Electronics Engineering is an Illinois electronic product design firm based in Addison, in DuPage County. We provide hardware, PCB, firmware, and complete product engineering with production in the same facility, and support clients across the state with on-site engineering where the work demands it.
One bench, the whole state
Illinois makes physical products — and nearly all of them now have electronics inside. The design capacity to support that sits mostly in one corner of the state. We run engagements statewide, structured so distance stays an inconvenience rather than a risk.
Chicago metro
The state’s industrial core: medical devices, automation, machine builders, and transportation. Close enough for same-day visits and courier runs — see the dedicated Chicago page.
Rockford region
A historic aerospace and precision-manufacturing cluster. Electronics for high-reliability applications, sustaining engineering for long-lived programs, and test equipment fit naturally here.
Peoria & the I-74 corridor
Heavy equipment and agricultural machinery country. Rugged controllers, sensor interfaces, harness design, and electronics that survive vibration, weather, and long service lives.
Champaign-Urbana & downstate
Research institutions and the startups they produce. Proof-of-concept builds, prototype engineering, and the path from a lab bench result to a manufacturable product.
How a statewide engagement works
Electronics design travels well: schematics, layouts, and firmware move over a video call as easily as over a conference table. What does not travel is hardware, so we structure statewide projects around the moments that need hands on metal. Kickoff and requirements happen at your site, where the product's real environment is visible. Design and reviews run remotely on a fixed cadence. Prototypes ship overnight, or you visit Addison for bring-up. Integration and line support put our engineers back on your floor.
The full engineering scope is available statewide — from complete product design and sustaining engineering to reverse engineering of products whose documentation is gone. Chicago-metro clients may want the Chicago page — proximity buys a few extra advantages there.
Questions about statewide work
Yes. Project kickoffs, requirements workshops, integration support, and production-line troubleshooting all happen at client sites across the state. Day-to-day engineering runs remotely with scheduled reviews, so travel is spent where being physically present matters.
We do. Illinois produces a steady stream of hardware startups, particularly out of the Champaign-Urbana and Chicago research communities, and early-stage teams are often exactly who needs a full engineering bench without hiring one. A first engagement can be as small as a feasibility study or a proof-of-concept prototype.
Often, yes. We are an Illinois business with engineering and production in Addison, which keeps both the design work and the manufacturing domestic — relevant for procurement policies that favor in-state or US-based suppliers, and for products where IP control matters. Documentation of where the work happens is straightforward, because it all happens in one place.
Any company whose product contains a circuit board. In practice that spans the state: aerospace suppliers around Rockford, heavy-equipment and agricultural manufacturers along the I-74 corridor, medical device and automation companies in the Chicago metro, and food-processing equipment makers throughout. The industries differ; the electronics discipline underneath them is the same.
