Technology for selective metal deposition on free shaped dielectric materials
Electric circuit traces formation on 3D shaped dielectrics is one of the highest challenges in 3D Mechatronic Integrated Devices (3D-MID). The Selective Surface Activation Induced by a Laser (SSAIL) method is an advanced technology for solving emerged production issues for electric traces. SSAIL contains 3 main steps: laser modification of the dielectric surface, chemical activation of modified areas and electroless plating of activated parts.
The 3D-MID (Mechatronic Interconnect devices) is a modern solution for today and future devices. MID is an integration of mechanical and electrical functions in injection molded (in case of plastics) or milled three-dimensional bodies. A part with electronic circuits directly integrated into a dielectric component – it offers material, weight and cost savings, by the elimination of connectors between separate PCBs, shortening process chain and integration of contact surfaces, e.g. for switches, sensors and antennas. 3D-MID has a great potential in automotive, aviation, lighting, computing or even medicine sectors where emerging innovation demands to increase the number of the electronic component into a device.
Technology offers laser writing speeds of up to 5m/s with galvanometric scanners, and herewith spatial plating pitch is kept narrow at 25µm for polymer. Spatial plating pitch for glasses, ceramics and transparent polymer can be achieved down to 3 µm. The main advantages of the SSAIL process comparing with the alternative methods, is that SSAIL can form electric circuit on standard dielectric materials and does not require special additives inside bulk, unlike LDS (Laser direct structuring) does not use metalorganic additives. Therefore, SSAIL could open a broad area of application where current methods of electronics integration are still too expensive.
Another advantage is related with SSAIL capability to process transparent and flexible polymers, ceramics, glasses or even silicon.

Every touchscreen is a device of numerous layers including a transparent conductive electrode. The current transparent conductive film market is dominated by expensive and fragile Indium-tin oxide electrodes, also known as ITO. However, ITO made from rare metal Indium. It results in a high-cost and brittle technology. There is a huge demand for alternative technologies to the ITO transparent electrode. New materials like carbon nanotubes, silver nanowires are still on the research stage and expensive as well. Most promising alternative is metallic mesh with metal wires less than 5 micrometers in diameter to be invisible but still electro-conductive. Our innovation allows us to produce a transparent – metal mesh electrode by electroless copper micro-plating technology induced by a precision laser writing.
