Additional Capabilities

More Ways We Support Your Engineering Needs

Along with our core services, we offer hands-on capabilities that help move projects from early concept to working prototypes. These skills allow us to test ideas quickly, refine designs, and solve problems that surface during development.

PCB Modifications
We update, repair, or adjust existing circuit boards to support new components, fix errors, or improve performance.
Firmware Debugging
We analyze and troubleshoot firmware issues to resolve crashes, timing problems, communication failures, and unexpected behavior
Hardware Debugging
We test, measure, and diagnose electrical issues on physical boards to identify faults, damaged components, or design weaknesses.
Soldering & Rework
We handle fine-pitch soldering, board repair, and component replacement for prototypes and small-batch builds.
Prototyping & Bench Testing
We build and refine early-stage prototypes to validate concepts and ensure hardware and firmware work together correctly.
3D Printing for Housings & Fixtures
We create custom enclosures, test fixtures, and functional parts to support product development and hands-on testing.
