Method for manufacturing trim panels for vehicles having an electronic function

Method for manufacturing trim panels (10) for vehicles having an electronic function comprising the following steps:

• a) providing a first sheet (1) comprising a flexible flat plastic film having a first area (1.1) being flat,
• b) printing an electrical conductive track (2.1) on the first sheet (1) with a first electrical conductive material (6) by screen-printing, inkjet printing, flexographic, gravure or offset lithographic printing,
• c) forming the first sheet (1) comprising the electrical conductive track (2.1) according to a three-dimensional shape in such a way that the first area (1.1) has a three-dimensional shape,
• d) printing an electrical conductive pad (2.2) connected to the electrical conductive track (2.1) on the first area (1.1) with a second electrical conductive ink (7) by fluid dispensing or pad printing,
• e) attaching an electronic component (3) to the electrical conductive pad (2.2) in order to said electronic component (3) can be electrically powered by said electrical conductive pad (2.2),
• f) injecting a plastic material on the first sheet (1) forming a carrier sheet (4) covering the electronic component (3), wherein the carrier sheet (4) comprises a second side (4.2) facing the first sheet (1) and a first side (4.1) opposite to the second side (4.2),
• g) providing a decorative covering (5) configured to be at the first side (4.1) of the carrier sheet (4) comprising a pictogram (5.1) configured for cooperating with the electronic component (3).
