CRM Group is at the forefront of innovation, leveraging advanced technologies to develop printed electronics solutions tailored to 3D objects operating in extreme environments. With applications spanning automotive, aerospace, steelmaking, and more, our cutting-edge research is redefining possibilities for smart, connected systems.

Originally, the development of Printed Electronics was rooted in the manufacturing of OLEDs (Organic Light Emitting Diodes) on steel for ArcelorMittal. In this context, CRM showcased exceptional OLED lighting performance on large stainless steel panels and even on low-carbon steel surfaces.

Comprehensive Pilot Lines for Printed Electronics

At the core of our expertise are our state-of-the-art pilot lines, which bridge the gap between laboratory research and industrial-scale production. These facilities enable high-precision processes, including wet coating, vacuum deposition, and thermal spray technologies, designed to handle a wide range of materials and configurations.

• 2D Pilot Line: Operating in an ISO 7 cleanroom environment, this line supports techniques like slot die coating and roll-to-roll processing, ensuring uniformity and scalability for electronic applications.
• 3D Pilot Line: Featuring advanced robotic systems and thermal spray technologies, this line enables the creation of complex electronic structures on 3D objects, with applications in sensors, conductive layers, and more.

These pilot lines are pivotal in ensuring reproducibility, performance, and compatibility with industrial requirements, particularly in environments that demand durability and precision.

Advancing Metal and shapeable  Printed Circuit Boards

One of CRM Group’s key innovations lies in the development of Metal Printed Circuit Boards (MPCBs), designed for applications in extreme environments. Using advanced metal substrates as a flexible yet robust support, these circuit boards offer:

• Superior heat dissipation capabilities.
• Compatibility with high-pressure and high-temperature environments.
• Integration of Surface-Mounted Device (SMD) components, enabling lightweight and efficient designs.
• Sheapable and conformable substrates  

In the automotive sector, these solutions replace traditional wiring harnesses, reducing vehicle weight and assembly time while supporting the transition to energy-efficient and autonomous vehicles.
