Abstract (en)
[origin: WO2021122428A1] The invention relates to a circuit board (10), comprising at least one electronic component (20) mounted on an exterior (11) of the circuit board (10). A plastic film (30), which has a film thickness (31) and a plurality of openings (32), is arranged between the at least one electronic component (20) and the exterior (11) of the circuit board (10) that is allocated to the component (20). The plastic film (30) is fastened to the exterior (11) of the circuit board (10). The openings (32) in the plastic film (30) are at least partially filled with conductive adhesive (50), and said openings (32) are positioned at the placement position (29) of the component (x) such that a conducting track portion (12) on the exterior (11) of the circuit board (10) is conductively connected to a contact pad (25) on the bottom (21) of the at least one component (20) by means of the conductive adhesive (50) within an opening (32). The invention further relates to a method for producing a circuit board (10) of this type.
