Abstract: A package structure includes a substrate, a plurality of conductive pads, a light-emitting diode, a photo imageable dielectric material, and a black matrix. The substrate includes a top surface. The conductive pads are located on the top surface of the substrate. The light-emitting diode is located on the conductive pads. The photo imageable dielectric material is located between the light-emitting diode and the top surface of the substrate and between the conductive pads. An orthogonal projection of the light-emitting diode on the substrate is overlapped with an orthogonal projection of the photo imageable dielectric material on the substrate. The black matrix is located on the top surface of the substrate and the conductive pads.

Abstract: A stacked structure includes a circuit board, an electronic component, metallic cores, and insulating cladding layers. The circuit board includes first bonding pads. The electronic component includes second bonding pads that are opposite to the first bonding pads. Each metallic core is connected to a corresponding first bonding pad and a corresponding second bonding pad. The metallic cores have a curved surface interposed between the corresponding first bonding pad and the corresponding second bonding pad. The insulating cladding layers are separated from each other and cover the curved surfaces of the metallic cores.

Abstract: A manufacturing method of a circuit board structure includes the following steps. A first sub-circuit board having an upper surface and a lower surface opposite to each other and including at least one conductive through hole is provided. A second sub-circuit board including at least one conductive through hole is provided on the upper surface of the first sub-circuit board. A third sub-circuit board including at least one conductive through hole is provided on the lower surface of the first sub-circuit board. The first sub-circuit board, the second sub-circuit board, and the third sub-circuit board are laminated so that at least two of their conductive through holes are alternately arranged in an axial direction perpendicular to an extending direction of the first sub-circuit board. The first sub-circuit board, the second sub-circuit board, and the third sub-circuit board are electrically connected to one another.

Abstract: A package structure includes a redistribution structure, a chip, one or more structural reinforcing elements, and a protective layer. The redistribution structure includes a first circuit layer and a second circuit layer disposed over the first circuit layer. The first circuit layer is electrically connected to the second circuit layer. The chip is disposed over the redistribution structure and electrically connected to the second circuit layer. The one or more structural reinforcing elements are disposed over the redistribution structure. The structural reinforcing element has a Young's modulus in a range of 30 to 200 GPa. The protective layer overlays the chip and a sidewall of the structural reinforcing element.
