An electronic component feeding apparatus comprises a feeding rotor having a recess for forming a parallel space with a plane orthogonal to the rotation axis. A method of manufacturing a service cart and a service cart kit are also provided. The pixel computation positions are selected to compensate for image distortions introduced by a display device andor display surface. A connection layer is applied at the backside of the carrier and in contact with the carrier. At least one of the layers offers improved resistance to high temperature stress relaxation.
