What Is Box Build
Assembly?
Box build assembly is the complete integration of electronics, mechanical parts, wiring and enclosures into one finished product.
We bring together PCBAs, custom mechanical parts, cables, connectors, interfaces and other components, then assemble, test and finish the complete system.
CHOOSING THE RIGHT FIT
When Box Build Assembly Makes Sense
Box build is the right process when several components and manufacturing processes need to come together into one working, tested product.
WHEN TO CHOOSE
01
Finished design
PCBs, mechanical parts and drawings are ready for complete assembly.
02
Multiple components
Electronics, mechanical parts, wiring and enclosures need to work together.
03
Prototype or small batch
You need a prototype, pilot build or flexible short production run.
04
Testing and QC
Every unit requires functional testing, inspection and documented QC.
WHEN IT MAY NOT BE NECESSARY
01
Single manufacturing process
You only need a PCB, machined part, molded component or similar individual process.
02
Early-stage concept
The product still needs engineering, prototyping or DFM development.
03
Very high automated volume
Large-scale automated production may require a dedicated production setup.

OUR STRONGEST GUARANTEE
No MOQ.
From 1 Unit to Production Volumes.
We don't impose a fixed minimum order quantity. Whether you need a single prototype, a small batch, a pilot run, or larger production quantities, we can support the requirement without asking you to commit to a volume you don't need yet.

QUALITY & TRANSPARENCY
Quality You Can See, Not Just Take Our Word For It
Every project follows defined quality checkpoints, with production updates that keep you informed from assembly through final inspection.
01
QC Transparency
Every project follows a structured QC checklist. If you have your own inspection checkpoints, we follow those instead and report against them.
- Customer-specific QC checklist
- Assembly & process-wise inspection
- Functional testing & final inspection
- Detailed QC report, pass/fail per checkpoint
- Traceable production documentation
02
Production Visibility
Know what's happening on your production floor. We send regular updates, including photos and videos during assembly, so you can follow your product's progress as it happens.
- Photo updates at key assembly stages
- Video walkthroughs on request
- Direct line to the engineer building your product
- No surprises at final delivery

WHO THIS IS FOR
Built for Products That Need More Than One Manufacturing Step.
When your product combines custom parts, electronics, mechanical assemblies, wiring, integration and testing, coordinating everything through separate vendors can become complicated. Our box build service brings those requirements together into one coordinated manufacturing workflow.
01
You Have a Finished Product Design
Your product is already designed and you need a manufacturing partner to turn the design into a finished, assembled product.
03
Your Product Combines Mechanical + Electronics
Your product requires mechanical components, electronics, cables, connectors, displays, switches or other elements to work together as one finished system.
05
You Need Multiple Manufacturing Processes
Your product requires custom parts such as injection molded components, CNC parts, die-cast components, sheet metal, PCB assemblies or wiring to come together in one build.

02
Your PCB Needs a Product Around It
You already have the PCB or PCBA, but still need the enclosure, mechanical parts, wiring, assembly and integration.
04
You Need Prototypes or Small Batches
You need a small number of complete units for validation, pilot production, testing or early market requirements before larger production.
06
You Want One Partner From Build to Testing
You want one manufacturing partner to manage assembly, integration, firmware loading where required, functional testing and final QC.
FAQ
Questions We Hear Before Every Project
What is box build assembly?
Box build assembly is the complete integration of electronics, PCBAs, mechanical parts, enclosures, cables, connectors, displays, switches and other components into one finished, tested product.
What products can you assemble?
Anything from a single-board device in a simple enclosure to multi-component electromechanical systems, across medical, industrial, consumer electronics, IoT, defense and agritech products.
Do you have a minimum order quantity?
No. We support single prototypes, small batches, pilot runs and full production quantities, without a fixed MOQ.
Can you handle small-batch or prototype assembly?
Yes, this is one of our core strengths. Many projects start as a single prototype before scaling into a production run.
