A motor assembly, comprising a brushless DC motor with control electronics which comprises at least two magnetic field sensors adapted to measure magnetic flux from magnetic poles on a rotor in the brushless DC motor. The lens unit includes an objective lens for collimating the output radiation and a filtering film for filtering the output radiation. The method and system further include exposing the mask layer to provide a mask. The cover tape may be then removed from the surface of the panel in order to produce a panel unit having the molded article disposed along the periphery of the panel.
