Abstract

A method of manufacturing a small electronic device includes intermittently feeding predetermined length of a base film, which forms a film strip; arranging electronic elements, e.g., a film-like liquid crystal display cell, a film-like solar cell and a printed circuit board, on a predetermined region of the film strip; arranging a frame on the film strip, so that the frame surrounds the electronic elements; depositing an adhesive onto the film strip; placing a panel on the film strip; moving press means on the panel from one end of the panel to the other end thereof, thereby pressing the panel and bonding the same to the film strip; and cutting the film, thereby forming a semifinished product. This method further includes detecting the position of the periphery of the semifinished product and trimming unfinished portions with a laser beam, thereby forming a finished product of a prescribed shape and size.
