The objective of this article is to demonstrate the possibility of using a stitching element as an alternative to the point-to-point connections that are used with traditional via technology. Point-to-point connections have the best performance in terms of signal integrity (one via less in the connection that distorts the signal). A via is mainly a capacitive element that causes signal loss/ dispersion.

ODB++: Transforming Ideas Into Products
The ODB format originated with the objective of delivering on this need. The format was originally introduced for use by PCB fabricators, eliminating the need for a collection of CAM files in multiple formats—such as Gerber, Excellon, IPC-356, or even IPC-350, which was an early attempt to simplify this process. The key to the success of ODB was that it obtained industry acceptance.
Standards: Why We Have Them and Live by Them
Have you ever designed a board but received feedback that it couldn’t be manufactured unless changes were made? Or maybe you’ve designed a complex board and sent it to the factory only to find out that the manufacturer didn’t build the board to your expectations? PCBs are becoming more complex, factory options are growing, and expectations for product life cycles are becoming longer.
