Abstract: A plate (such as a printed circuit board) is mounted and immobilized on a base (such as a chassis of a television receiver) by performing the following sequential steps: affixing mounting plugs on the base; positioning an apertured plate on the mounting plugs such that the head of each mounting plug projects through an opening of the plate and the plate rests on a support face of each plug; sliding the plate in its plane in a predetermined direction into a position in which an underside of each mounting plug head is situated immediately above a surface portion of the plate and edge portions defining the plate openings are in an abutting relationship with the respective mounting plugs; and bringing a component into an abutting relationship with a trailing edge of the plate subsequent to completion of the sliding step for preventing the plate from being shifted opposite the predetermined direction, whereby the plate is immobilized.
