Abstract

The present invention includes an aluminum board, an electromagnet core, and a coil. The aluminum board includes a first surface, a second surface opposite to the first surface, and multiple through vias in communication with the first surface and the second surface. The electromagnet core is mounted on the first surface, and the through vias are located on two opposite sides of the electromagnet core. The coil is mounted through the through vias to wrap around the electromagnet core. An inside wall of each of the through vias forms an anodic aluminum oxide (AAO) by an anodizing process. The present invention is able to decrease via size of a conductive through via of a vertically embedded inductor. This allows through vias to be more densely formed on a board, and thus increases an amount of the coil wrapped around the electromagnetic core and increases inductance of the inductor.

Abstract

A packaging method includes steps of: forming first and second wiring layers electrically connected to each other on two opposite surfaces of a substrate; then configuring mother substrate interconnecting bumps on the first wiring layer and along perimeter of a daughter substrate unit, and then cutting along the perimeter of the daughter substrate unit to expose lateral faces of the mother substrate interconnecting bumps and configuring solder materials thereon; then configuring first and second chips on the first and the second wiring layers to form electrical interconnection between the two chips. A package structure enables interconnecting two chips through one single daughter substrate unit with its wiring layers directly connecting with lateral face contacts of the mother carrier substrate through the mother substrate interconnecting bumps. Hence, area of the daughter substrate unit is reduced; lengths of the interconnection paths are shortened, and qualities of communication and space utilization are enhanced.

Each of the protuberant parts has a convex curved surface, in which the distance between the convex curved surface and the axis of the through hole is less than the radius of the through hole.

Abstract

A circuit board structure includes a redistribution structure layer, a build-up circuit structure layer, and a connection structure layer. The redistribution structure layer has a first and second surface, and includes an inner and outer dielectric layer, first connecting pads, and chip pads. A bottom surface of each first connecting pad is aligned with the first surface, and the chip pads are protruded from and located on the second surface. The build-up circuit structure layer includes second connecting pads. The connection structure layer is disposed between the redistribution structure layer and the build-up circuit structure layer and includes a substrate and conductive paste pillars penetrating the substrate. The first connecting pads are electrically connected to the second connecting pads via the conductive paste pillars, respectively. A top surface of each conductive paste pillar is aligned with the first surface of the redistribution structure layer.
