Abstract:
Disclosed herein are a printed circuit board and a process of manufacturing the printed circuit board. The printed circuit board includes an insulating layer, and circuit layers disposed at both sides of the insulating layer, each of the circuit layers including a land part and a pattern part. The land parts formed on both sides of the insulating layer are coupled to each other using electrical resistance welding. There is no need for a separate interlayer connection structure such as vias or bumps and a process of forming the interlayer connection structure, thus simplifying the printed circuit board and the process.
Abstract:
The present invention relates to a high density printed circuit board and a method of manufacturing the same which enable a thin printed circuit board to be manufactured and can overcome problems occurring in a conventional method of manufacturing a printed circuit board because a conventional CCL is not used as a raw material. The high density printed circuit board includes a first insulating layer having a constant thickness, and a pair of first circuit layers embedded in two sides of the first insulating layer, respectively.
Abstract:
Disclosed are a printed circuit board for improving the tolerance of embedded capacitors and a method of manufacturing the same. The printed circuit board having embedded capacitors is manufactured by transferring and embedding a circuit layer having a lower electrode formed through an additive process into a resin insulating layer, and thereby is minimized in the circuit tolerance conventionally caused by an etching process to thus be applied to capacitors for RF matching.
Abstract:
Provided is a ball grid array substrate, a semiconductor chip package, and a method of manufacturing the same. The ball grid array substrate includes an insulating layer having a first surface providing a mounting region for a semiconductor chip, a second surface opposing the first surface, and an opening connecting the second surface with the mounting region of the semiconductor chip, and a circuit pattern buried in the second surface. Since the ball grid array substrate is manufactured by a method of stacking two insulating layers, existing devices can be used, and the ball grid array substrate can be manufactured as an ultra thin plate. In addition, since the circuit pattern is buried in the insulating layer, a high-density circuit pattern can be formed.
