Our solutions – a quick overview
"Everything from a single source" –
from design to shipping
Lead time reduced by 80%
Rapid Prototyping
Everything from a single source: from PCB manufacturing through assembly and testing to shipping. This reduces interfaces and coordination efforts, improves quality, and shortens lead time by 80%. Even complex multilayer designs can be realized within just a few days, while individual evaluation boards ("eval-boards") can be produced within a few hours. Since manufacturing, assembly, and testing are carried out entirely in-house, there are no dependencies on external supply chains.
New design freedoms in electronics and mechatronics
Additively manufactured
electronics & mechatronics
Grüninger offers not only additively manufactured electronic components such as antennas, RF elements, and filters, but also complete mechatronic assemblies. Our technology enables higher signal integrity through reduced reflections and losses. Targeted EMC shielding and coaxial routing effectively prevent crosstalk. In addition, passive filter systems can be realized without complex manual tuning, and mechatronic functions can be directly integrated into electronic structures.
System sustainment
PCB sustainment solutions
Our technology enables spare parts and system sustainment beyond the original lifecycle. With printable interposers for obsolete components, legacy systems remain fully operational – even when original parts are no longer available. 1:1 reconstructions of legacy PCBs eliminate the need for costly redesigns of entire boards and extend the service life of safety-critical legacy solutions. The key advantages are independence from supply chain and security risks thanks to complete production in Germany.
Innovative security concepts
Hardware Security
Additively manufactured "Smart & Secure" enclosures are individualized through physical unclonable functions (PUFs), making them fully tamper-proof. 3D printing enables integrated EMC shielding that protects sensitive assemblies. By embedding components and utilizing chip-stacking technologies in system-in-package (SiP) approaches, we achieve a new dimension of functional and integration density.
