PCB assembly and box build production at CADLETE Designs

Our Box Build Manufacturing Process

The same PCB assembly to finished product workflow whether it is your first production run or your fifth.

01

Design Review & DFM

Your PCB and mechanical files are reviewed for manufacturability before tooling or fabrication starts, so problems get caught on screen, not on the line.

02

PCB Fabrication & Assembly

Bare boards are fabricated and populated, with automated optical inspection on every panel before it moves to the next stage.

03

Firmware & Functional Test

Firmware is flashed and every unit runs through a functional test jig, confirming the board actually works before it goes into an enclosure.

04

Enclosure & Sub-Assembly Integration

The tested PCBA is integrated into its enclosure, with cables, connectors, and any mechanical sub-assemblies fitted and secured.

05

Final QC & Packaging

A full visual and functional inspection pass, then the unit is packed and ready to ship, whether that is to you or straight to your customer.

Where Box Builds Matter Most

Box build needs vary by product category, but the underlying process, assemble, flash, test, ship, stays the same.

IoT Products

Connected devices and sensor systems shipped ready to pair.

Consumer Electronics

Smart devices and embedded interfaces built to retail quality.

Industrial Systems

Monitoring and automation hardware built for continuous duty.

Medical Devices

Embedded control and sensing systems, built to a documented process.

Mobility & Automotive

Embedded monitoring and communication hardware for vehicles and fleets.

Smart Infrastructure

Connected control and sensing platforms for buildings and sites.

What Founders Ask Before Their First Box Build Run

What is included in a "box build" versus just PCB assembly?

A box build takes the finished, tested printed circuit board and integrates it into its enclosure, connects cables and sub-assemblies, flashes and verifies firmware, and packs the unit ready to ship. PCB assembly alone stops at the populated board; a box build is the complete, sellable product.

Can you box build from a design that is not fully finished yet?

Yes. If your PCB or enclosure design still needs work, our engineering team reviews it for manufacturability first, so tooling and fabrication do not start on a design that will need rework later.

What is the minimum order quantity for a box build run?

We work with founders on their first production run, not only repeat large volume orders, so batch sizes are set to what a small or first time run actually needs, rather than a high volume minimum.

How do you handle IP protection on a box build project?

A non disclosure agreement is signed before any design file, schematic, or firmware is shared with our team, and it stays in place for the life of the engagement.

Working with Cadlete Designs has been a real pleasure. They helped with so many design aspects I hadn't considered and offered many suggestions that I would have never thought of. Professional, prompt, and always willing to go the extra mile. I was extremely lucky to have found them! (Patent Pending)
