We have previously shown that a saw-tooth surface with only horizontal vibration, simple planar and symmetric, can feed along microparts. The microparts move forward because they adhere to the saw-tooth surface more in the backward direction than in the forward direction. We studied the movement of smaller 0603-type capacitors (size: 0.6×0.3×0.3 mm, weight: 0.3 mg). The capactors rotated on the saw-tooth surface because the pitch was relatively large for the 0603-type capacitors. We examined the decrease of feeding velocity caused by the rotational motion of the smaller capacitors.
