Abstract:
There are provided a package board, a method for manufacturing the same, and a package on package having the same. The package board according to an exemplary embodiment of the present disclosure includes a first insulating layer formed with a cavity having a penetrating shape; and a first connection pad formed to penetrate through the first insulating layer and formed at one side of the cavity.
Abstract:
A printed circuit board including: a first insulating layer; a first wiring layer disposed on an upper surface of the first insulating layer, and including a first wiring portion and a second wiring portion; and a second insulating layer disposed on the upper surface of the first insulating layer, having a cavity exposing an upper surface of the second wiring portion, and including a first insulating portion covering the first wiring portion and a second insulating portion whose upper surface is exposed from the cavity, wherein one or more gaps are provided between the second wiring portion and the second insulating portion.
Abstract:
A printed circuit board connected to one surface of a substrate and a first electronic component is mounted on the one surface. The printed circuit board includes at least one insulating layer and the insulating layer has a cavity accommodating at least a portion of the first electronic component formed therein, and the cavity has an internal surface made of an insulating material.
Abstract:
Disclosed herein is a circuit board including a heat transfer structure formed of a highly thermal conductive material, wherein a part of the heat transfer structure excluding an air cooling unit exposed to outside of an insulation unit is inserted into an insulation unit, and the air cooling unit has a shape having a high non-surface area such as a wrinkled or uneven shape.
Abstract:
Disclosed herein is a circuit board. According to an exemplary embodiment of the present disclosure, a circuit board has a structure in which at least a portion of a first heat transfer structure in which a metal layer and an insulating layer are alternately stacked is inserted into an insulating part.
