Student Laser surface modification by an angle for electroless copper deposition on polymers.Thursday (25.06.2020) 17:00 - 17:20 Room 3
Advanced process for electric circuit traces formation on 3D shaped polymers is presented. The Selective Surface Activation Induced by a Laser (SSAIL) method is a promising technology , consists of 3 main steps: 1. Laser modification of the surface. 2. Chemical activation of modified area. 3. Electroless copper deposition on the modified area. The process can be exceptionally applied to standard commercial dielectric materials such as PC-ABS, LCP, PEEK plastics, ceramics, glasses, and polymeric films.
The aim of research was to apply laser writing technique by differet angles of incidence and find best parameters and techniques for high-quality electric circuit traces formation on 3D surfaces. Sheet resistance, optical, and scanning electron microscopy measurements were applied for investigate the optimal processing parameters. In the experiment high repetition rate picosecond pulsed laser and a galvanometric scanner for fast and precise pulse delivery on surface were used.
