Abstract

The invention provides a printed circuit board and a method of manufacturing the same. The printed circuit board includes an insulating layer and a circuit layer disposed on the insulating layer. The circuit layer includes a first circuit pattern and a second circuit pattern. Each of the first circuit pattern and the second circuit pattern has a first side surface, a second side surface opposite to the first side surface, and a top surface connected to an end of the first side surface and an end of the second side surface when viewed from a cross section. The first side surface of the first circuit pattern and the first side surface of the second circuit pattern face each other. A height of the first side surface of the first circuit pattern is greater than a height of the second side surface of the first circuit pattern, and a height of the first side surface of the second circuit pattern is greater than a height of the second side surface of the second circuit pattern.

Description

[0001] This application claims the benefit of priority of Korean Patent Application No. 10-2020-0133219 filed on October 15, 2020 at the Korean Intellectual Property Office, the entire disclosure of which is hereby incorporated by reference. technical field [0002] The present disclosure relates to a printed circuit board and a method of manufacturing the printed circuit board. Background technique [0003] Recently, high-density printed circuit boards (PCBs) are required in the electronic component industry to support 5G high-speed communications and artificial intelligence (AI). Microcircuit technology is important for high-density PCBs, and research and development are currently underway to reduce line widths and spaces of circuit patterns. [0004] Common circuit formation methods implemented in the field of PCB design are semi-additive process (SAP), modified SAP (MSAP), sealing holes (TT), and the like. However, such a plating process is limited in reducing the line ...
