Abstract in different language:	A new 3-D laser micromachining method of 3-D flexible structures has been introduced to enhance the current micromachining technology. The machining is carried out with a simple 2D movement of the laser beam on the work piece. This method can be applied for machining 3-D geometries or bending edges in various materials. The purpose is to extract the material by an ablation of matter in order to achieve “V” shape for multi-bend structure. The process is well controlled and only selective polyimide material removing on bending edges was used. Two-layered polyimide-copper assembly was considered. This is a practical case for multilayer structures such as layered composites and coatings. The mechanical bending analysis of the system with residual stress was carried out with COMSOL Multiphysics. Variations in strain and stress of the structure are demonstrated. Dynamic bending features were also measured and compared to a non laser cut and bended substrate. It’s mechanical reliability is improved.
