Abstract

The present invention provides printed circuit boards having circuit layers laminated with stacked (or staggered) micro via(s) and methods of manufacturing the same. Aspects of embodiments of the present invention are directed to a printed circuit board with Z-axis interconnect(s) or micro via(s) that can eliminate a need for plating micro vias and / or eliminate a need for planarizing plated bumps of a surface, that can be fabricated with one or two lamination cycles, and / or that can have carrier-to-carrier (or substrate-to-substrate) attachments with conductive vias, each filled with a conductive material (e.g., with a conductive paste) in the Z-axis. In one embodiment, a printed circuit board having a plurality of circuit layers with at least one z-axis interconnect can be fabricated using a single lamination cycle.

Description

[0001] Cross-Referenced Related Applications [0002] This application claims priority from US Patent Application No. 11 / 706,473, filed February 14, 2007, and US Provisional Application No. 60 / 793,370, filed April 19, 2006. field of invention [0003] The present invention relates generally to printed circuit boards and methods of making the same, and more particularly to printed circuit boards having laminated circuit layers with stacked (staggered) microvias and methods of making the same. Background technique [0004] Most electronic systems include printed circuit boards with high density electrical interconnections. A printed circuit board includes one or more circuit cores, a substrate, or a carrier. In a fabrication scheme for printed circuit boards having one or more circuit carriers, electronic circuits (i.e., pads, electrical interconnections, etc.) are formed on opposite sides of a circuit carrier to form a pair of circuit layer. The resulting circuit board str...
