Define the right engineering scope
We assess whether a complete hardware project or a clearly defined work package best fits your current situation.

Entwicklungsprozess
Structured development process
We tailor the workflow to the project: from requirements and architecture through prototypes and reviews to documented handover.

PHASE 0
Requirements & Architecture
Requirements engineering and system conception.
In this phase, we define the system requirements and develop the fundamental concept. We select critical core components (BOM), define interfaces, and create an initial block diagram. The goal is a solid system architecture that minimizes technical and economic risks early on.

PHASE 1
EVT (Engineering Validation Test) & Firmware
First functional prototypes and parallel firmware development.
In the EVT phase, we combine 'looks-like' and 'works-like' into one form factor using production-intent materials for the first time. We identify design issues through rigorous functional, performance, and reliability testing. In parallel, we develop custom firmware to directly support hardware bring-up.

PHASE 2
DVT (Design Validation Test)
Verification of the production-ready design and tool qualification.
DVT verifies mass production yields with a single, production-worthy design. We qualify the first hard tools for every component. The goal is to ensure high reliability during assembly on the production line and to resolve any remaining sources of failure.

PHASE 3
PVT (Production Validation Test)
Verification of mass production under real manufacturing conditions.
PVT is the final step before scaling. Units built here are intended to be sold to customers (provided they pass all tests). We verify production yields at mass production speeds, train operators, and ensure all End-of-Line (EoL) test stations function smoothly.

PHASE 4
Handover & NPI Support
Handover of manufacturing data and New Product Introduction (NPI) support.
The final step of our development is the seamless transition to manufacturing. We provide you with the complete, verified data package (Gerber files, ODB++, BOM, Pick & Place, 3D CAD). Furthermore, we support your EMS provider during the New Product Introduction (NPI) process, clarify Design for Manufacturing (DFM) details, and assist in defining the End-of-Line (EoL) testing environment.
