Abstract: A flexible printed circuit board including a terminal includes a flexible printed circuit board that includes an electrically conductive line and the terminal soldered to the flexible printed circuit board. The flexible printed circuit board includes a land and a soldering restricting section. The land is electrically connected to the electrically conductive line and has a metal surface and is soldered to the terminal. The soldering restricting section has a non-metal surface and is not soldered to the terminal. The terminal includes an overlapping section and a protrusion section. The overlapping section overlaps the land and is soldered to the land and includes a removed section that is formed in such a manner that a portion is partially removed in a predefined area. The protruding section is continuous from the overlapping section and protrudes to an area that does not overlap the flexible printed circuit board.

Abstract: A method of forming a multi-layer circuit on a curved substrate includes forming, by a laser direct structuring process, a first layer of the multi-layer circuit on a first surface of the curved substrate. The method includes applying a first layer of paint to the first layer of the multi-layer circuit. The method includes forming, by the laser direct structuring process, a second layer of the multi-layer circuit on the first layer of the paint and electrically coupled to the first layer of the multi-layer circuit. The method includes applying a second layer of paint over the second layer of the multi-layer circuit and forming, by the laser direct structuring process, a third layer of the multi-layer circuit on the second layer of the paint and electrically coupled to the second layer of the multi-layer circuit.

Abstract: A component carrier includes a layer stack formed of an electrically insulating structure and an electrically conductive structure. Furthermore, a bore extends into the layer stack and has a first bore section with a first diameter (D1) and a connected second bore section with a second diameter (D2) differing from the first diameter (D1). A thermally conductive material fills substantially the entire bore. The bore is in particular formed by laser drilling.

Abstract: A glass substrate includes a plurality of through holes that penetrate from a first surface to a second surface of the glass substrate. Each through hole has an upper aperture with a first diameter on the first surface and a lower aperture with a second diameter on the second surface. For each of ten through holes selected from the plurality of through holes, a side wall length is obtained from the first and second diameters and the thickness of the glass substrate, and an R value is obtained by dividing the side wall length by the thickness of the glass substrate. The R values fall within a range of 1 to 1.1. A B value, obtained from dividing a difference between the greatest R value and the smallest R value by an average of the R values followed by multiplication with 100, is 5% or less.
