Method for applying an optical coupling medium

摘要

The intention of a method for applying an optical coupling medium for optical coupling of a light-emitting semiconductor chip (1) to a photodetector semiconductor chip (2), which chips are fitted on two mutually separated conductive tracks (3, 4) and are arranged mutually coplanar, in which a drop (5) of a transparent curable plastic is applied onto the coplanar chip arrangement (12), is to guarantee a defined and reproducible drop shape for the coupling medium. The sides of the conductive strips (3, 4) which are provided with the chips (1, 2) are turned downwards and the drop (5) is applied from above in a drop-formation process in such a way that the two chips (1, 2) on the bottom side of the conductive strips (3, 4) are uniformly encapsulated in a drop shape. Field of application: reflex optical coupler.
