An integrated approach for a seamless transition between prototyping and production
Since 2005, our rapid prototyping units, located directly within our production sites, have enabled us to quickly meet the functional validation needs of electronic boards before their transition to mass production. By integrating design, manufacturability, and testing, we help reduce time-to-market and optimize product reliability.
With simplified processes and a dedicated organization, we ensure responsiveness and technical expertise. 100% of serial (and pre-series) products go through a prototyping phase, a critical step before design freeze Nouvelle fenêtre. Moreover, our rapid prototyping lines, equipped like serial production lines, guarantee a smooth transition to industrial manufacturing.

A state-of-the-art industrial environment for high-performance prototypes
Our prototyping units are equipped with high-value industrial tools:
- Screen printing and SMT placement machines: Providing optimal precision for component assembly,
- Reflow oven and vapor phase (ASSCOM QUICKY800): Ensuring assembly quality for the most demanding components,
- Mobile probe tester TAKAYA APT9400: Rigorous control of printed circuit boards,
- Soldering and repair equipment: Maximum flexibility for quick adjustments.
This infrastructure enables the production of functional prototypes in record time while maintaining optimal quality.
