Astrolight holds a unique technology that enables cost-effective electroless metal plating on 3D surfaces – Selective Surface Activation Induced by Laser (SSAIL). SAIL is a patented technology for additive metallization directly onto the dielectric material by modifying surface properties with a laser. It has been developed in Center for Physical Sciences and Technology, Lithuania and licensed to Astrolight. Lasers can write the circuits directly by modifying the surface of polymers followed by an electroless metal plating.
SSAIL is a three-step process: surface modification by laser, chemical activation and electroless metal plating. Compared with other metallization processes, SSAIL requires no special additives and circuits can even be printed on transparent and flexible substrates. The new technology offers laser writing speeds of up to 4 m/s, and spatial plating pitch as small as 25µm.
The project of Smart IoT antennas – “DAIKTENA” was funded by the Agency for Science, Innovation and Technology of Lithuania.
