We previously showed that microparts can be fed along an asymmetric fabricated surface using simple planar symmetric vibrations. Microparts move forward because they adhere to the saw-toothed surface asymmetrically. In this study, we assessed the feeding dynamics of 0402-type capacitors (size, 0.4×0.2×0.2mm; weight, 0.1mg) along an asymmetric surface microfabricated by the double-pulsed femtosecond laser irradiation. We evaluated asymmetry of the fabricated surface based on measurements using an atmic force microscope. Profile models of both the fabricated surface and a 0402-type capacitor were approximated by polynomials. We examined contacts between the two models and asymmetry of contact by calculating contact area that acts adhesion. We formulated feeding dynamics of a micropart including adhesion, and also we conducted feeding simulations using the derived dynamics. Finally, to evaluate the derived dynamics, we compared simulation results with experimental results.
