We design and build the test and prototyping hardware your team needs.
From early prototypes to test fixtures to built-to-print modules rolled out across your teams. A few units or a few thousand.
Prototypes, test fixtures, and built-to-print modules for consumer, medical, defense, and communications programs — all designed and built in one building in Sunrise, Florida.
Small enough that the engineer who scopes your station is the engineer who builds it. Large enough to hold a 2,000-unit rollout to schedule.
Four disciplines. One building. No handoffs.
Our mechanical, electrical, and firmware engineers design the fixture, the interface board, the control software, and the harness, then hand it to a manufacturing and assembly team down the hall. When the DUT changes, the people who built it are the ones revising it.
A test station is an ME, EE, and software problem at once. Ours work in the same room.
Pogo alignment, mating force, interface board, harness, and instrument control are designed against each other from day one — not reconciled after the first fixture won’t close.
Mixed-signal boards are our deep end, not a task we farm out.
Analog front ends, precision measurement, power, and digital control on one high-density board — partitioned, grounded, and assembled to your requirements.
Low volume, high complexity is the whole business.
Machined, printed, and molded parts, cable and harness build, electro-mechanical integration, test and ship. Three stations is a normal job — so is two thousand test modules rolled out across a global engineering organization.
“Readix is my go-to supplier whenever we have a project that is complex, high-priority or multi-staged — over 70 projects to date. Projects are always well-planned, with risks identified and solutions presented.”
“Readix is the best engineering service company I have worked with. Best of all, they are a true partner working with you on a daily basis.”
“An excellent supplier that consistently delivers a quality product on time at a reasonable price — and instrumental in improving the design and reliability of circuit cards used in avionics test equipment for the US Navy.”
An extension of your team, not another vendor.
The clients we work best with treat Readix as capacity inside their own organization — the group that absorbs the non-core work so their engineers stay on the product, and that can flex both technically and administratively as priorities move.
Non-core work leaves your plate
Fixtures, stations, layout, and test software are essential and rarely why your engineers were hired. That work is our core.
Flexible on scope
We shift between mechanical, electronics, mixed-signal board design, firmware, and build without a new statement of work each time.
Flexible on paperwork
Fixed fee, milestone, or monthly block — under your PO structure, NDA, PLM, and revision control.
The same engineers next time
No re-onboarding on the next program. The team that learned your product keeps it.
Deep in test systems and mixed-signal electronics — with the floor that turns both into hardware.

Requirements get agreed before anything gets designed.
Most test programs go wrong in the first two weeks — a spec that was never written down, or a concept nobody outside the room reviewed. So we start by understanding your need and the gaps on your side, then analyze the requirements and walk them through with your engineers before a single part is drawn.
FOUNDER, LOCKHEED SKUNK WORKS
“Engineering shall always be within a stone’s throw of the airplane.” Ours sits beside the machines.
Understand
What you are building, what has to be tested, where the gaps are, and which work your own engineers should not be carrying.
Requirements analysis
Throughput, coverage, and interface requirements analyzed against your DUT — then reviewed with your team line by line until we agree.
Concept
A concept with cost and schedule, refined against your feedback until it is the system you actually want built.
Detailed design, documentation & implementation
Released design, then machining, harnessing, assembly, and functional test on our floor — hardware, not just a package.
The best builders have always put design next to the shop.
“If your hand is on a stove and it gets hot, you pull it right off, but if it’s someone else’s hand on the stove, it will take you longer to do something.”
VIA W. ISAACSON, ELON MUSK (2023)
The engineer who drew the part hears about it the moment it’s hard to machine.
“People in research, design, sales, and production must work as a team, to foresee problems of production and in use.”
OUT OF THE CRISIS, POINT 9
Requirements get reviewed by the people who will build and test the station.
“The design process is about designing and prototyping and making. When you separate those, I think the final result suffers.”
FORMER CHIEF DESIGN OFFICER, APPLE
WIDELY ATTRIBUTED — ORIGINAL SOURCE UNCONFIRMED
Design, prototype, and build stay under one roof, so nothing gets lost between them.
Development and factory test engineers
The test plan is written and the DUT exists. What’s missing is the hardware to run it — a fixture, a station, or an automated cell. We build it so your engineers stay on the product.
Hardware teams that need a custom mixed-signal board
Sensitive analog next to noisy digital and power, packed into a tight footprint. We engineer and assemble the board — or review yours before it goes to fab.
Labs and R&D groups with a setup that only works once
A bench of clip leads and a laptop proves the result. It doesn’t survive a second operator. We turn it into a repeatable, documented station somebody else can run.
Station types we have designed, built, and shipped.
Every one of these went out as working hardware — concept through managed manufacturing, deployed to factory floors and development labs.
Panel-level test systems
Multi-PCB panel testers with conducted RF test and active air cooling. Electronics, mechanics, and concept development in one scope.
Singulated board test

Flexible rack-mounted test and development platforms with application-specific software — deployed worldwide.
One module, or one for every engineer in the company.
A test module or jig that works on one bench usually has to exist on fifty. At large clients that number reaches the low thousands — every development team, every test lab, every site. Readix builds and ships the whole fleet: assembly, harnessing, integration, and functional test in-house; machining, PCB fabrication, and specialized processes through a vetted partner network.
Build to our design or build to your released print. Readix holds the quote, the schedule, and the quality record — one company from purchase order to hardware on your engineers’ benches.
Stations for one lab
First articles and pilot stations — assembled and documented like production work, so the rollout that follows is a repeat run and not a redesign.
Rollout across teams and sites
One module per development team, one jig per line. Too many to hand-build internally, too few for a contract manufacturer to quote — the gap where most of our build work sits.
Fleet programs for large organizations
Standard test hardware deployed org-wide and kept alive over years — repeat runs, ECOs, spares, and refurbishment handled as they come.
