Abstract

An electronic device comprises a flexible, printed circuit board having an electrically conductive layer (2) on one side of the flexible board, and a conductive metallic stiffener (8) which is attached to the flexible board. Said conductive layer (2) is conductively connected to the metallic stiffener (8) by means of solder. The flexible board is provided with a through-hole (10), the solder connecting the metallic stiffener (8) with the conductive layer (2) being present in said through-hole (10).
