Arrangement for mounting components on a carrier board and method of indicating mounting locations

Abstract

The mounting locations for .[.separable.]. insertion of components on a printed circuit board are indicated by a projected luminous .[.spot which is moved sequentially and repeatedly between the several mounting spots for each component. The direction of movement of the luminous dot is changed in each mounting spot..]. dot which moves from one mounting spot to the next to indicate the array of mounting spots forming the mounting location. The movement is cyclically repeated in the same sequence to indicate to the installer the mounting location. Thereafter the luminous dot is moved to the next mounting location and the same cyclical and sequential scanning is repeated. The spot travels over the board in response to an element of the optical system in the projector being moved in a plane parallel to the board surface under control of a programmed unit.
