Box-Build Assembly

From assembled boards to finished products ready to ship. We handle the final integration, programming, testing, and packaging so you get complete devices, not loose components.

What We Build

Complete System Integration:

• PCB assembly into enclosures and housings
• Cable assembly and internal wiring
• Display and user interface integration
• Sensor mounting and calibration

Device Programming:

• Microcontroller and FPGA programming
• Firmware loading and verification
• Device configuration and parameter setting
• Serial number and calibration data entry

Protection and Finishing:

• Conformal coating application (manual process)
• Environmental sealing and gaskets
• Label application and product marking
• Custom packaging and documentation

We turn your designed electronics into finished products ready for testing, certification, or immediate deployment.

Our Assembly Process

Component Integration

Your assembled PCBs arrive and we integrate them into enclosures with all mechanical components, displays, and interfaces.

Internal Wiring

Cable assemblies, connectors, and internal wiring completed according to your specifications and drawings

Programming and Configuration

Devices programmed with your firmware, configured with specific parameters, and verified for correct operation.

Protective Coating

Conformal coating applied by hand to protect circuits from moisture, dust, and environmental conditions.

Final Testing

Complete system testing according to your test procedures. Functional verification before packaging.

Packaging and Documentation

Products packed according to your requirements with documentation, certificates, or user materials included.
