Abstract:
Multichannel RF Feedthroughs. In some examples, a multichannel RF feedthrough includes an internal portion and an external portion. The internal portion includes a top surface on which first and second sets of traces are formed. Each set of traces is configured as an electrical communication channel to carry electrical data signals. The external portion includes a bottom surface on which the first set of traces is formed and a top surface on which the second set of traces is formed. A set of vias connects the first set of traces between the top surface of the internal portion and the bottom surface of the external portion.

Abstract:
Enlarged spacing is provided between rows of vias in a ball grid array (BGA) multilayered printed wiring board land pattern in which the lands in the pattern are connected to the vias by a link connector by rotating, elongating, and/or truncating selected consecutive link connectors and rotating their respective corresponding vias in a row or column or selected consecutive rows or columns to achieve the enlarged spacing between rows or columns of vias in the BGA land pattern. Enhanced spacing between selected grid columns or rows of vias is provided such that some of the grid pitches for the vias are equal to that of the standard BGA and at least some are of a greater grid pitch.
