A circuit board having a removing area is provided. The circuit board includes a first dielectric layer, a first laser resistant structure disposed on the first dielectric layer and located at the periphery of the removing area, a second dielectric layer disposed on the first dielectric layer, a circuit layer disposed on the second dielectric layer, a second laser resistant structure disposed on the second dielectric layer and located at the periphery of the removing area, and a third dielectric layer disposed on the second dielectric layer. The second laser resistant structure is insulated from the circuit layer. There is a gap between the second laser resistant structure and the circuit layer, and the vertical projection of the gap on a first surface overlaps the first laser resistant structure. The third dielectric layer exposes the portion of the circuit layer within the removing area.

The method includes the steps of: providing a substrate, wherein the substrate includes a metal layer, an insulation layer, and a first conductive layer, of which the insulation layer is positioned between the metal layer and the first conductive layer, and the metal layer is thicker than the first conductive layer; removing the partial metal layer for forming a metal bulk; providing an adhesive layer, wherein the adhesive layer includes an opening, and the opening is corresponding to the metal bulk; providing a second conductive layer; laminating the second conductive layer, the adhesive layer and the substrate; forming a hole in the insulation layer and the first conductive layer, wherein the hole is positioned under the metal bulk; forming a third conductive layer in the hole.
摘要:
A system has a processor coupled to access a document database that indexes keywords and instances of entities having entity types in a plurality of documents. The processor is programmed to receive an input query including one or more keywords and one or more entity types, and search the database for documents having the keywords and entities with the entity types of the input query. The processor is programmed for aggregating a respective score for each of a plurality of entity tuples across the plurality of documents. The aggregated scores are normalized. Each respective normalized score provides a ranking of a respective entity tuple, relative to other entity tuples, as an answer to the input query. The processor has an interface to a storage or display device or network for outputting a list including a subset of the entity tuples having the highest normalized scores among the plurality of entity tuples.
