A PRINTED BOARD ASSEMBLY AND A METHOD |
摘要 |
<p>The present invention relates to a method and a printed board assembly for use in a MicroTCA system, wherein backplane pin connectors of the printed board assembly are arranged to be received in receiving connectors of a backplane interconnect, characterized in that it comprises at least one switch unit which is arranged with physical output/input ports that have physical port numbers that can be overridden by logical port numbers, an optimal routing of a number of sets of conductive threads in the printed board assembly arranged so that none of the conductive threads cross over each other while connecting physical output/input ports of the switch units with the backplane pin connectors, and printed circuit board layers ar- ranged to shield signals travelling in the conductive threads in conductive layers of the printed circuit board layers from any significant crosstalk.</p> |
