Crossbow™ Matrix 8x8 Signal Trace Routing Guidelines For Backplane And Daughtercard Connectors
■1.1 Intent The intent of this technical bulletin is to outline the standard signal trace widths, minimum spacing requirements, and finish hole size requirements for the CrossbowTM Matrix 8x8 connector series (includes 8x8 and 8x9 configurations for Crossbow and Crossbow+) when used in differential signal applications and low speed applications. This document supercedes all other CrossbowTM Matrix 8x8 documents including customer use drawings when conflicts exist for the stated requirements outlined within this document.
■1.2 Efficient routing Efficient routing of signal traces between connector patterns improves yields and manufacturability. Spacing between trace/pad and trace/trace needs to be considered to allow for proper feature modifications needed for the inner layer fabrication process. Failure to allow for this will result in lower yields and higher PWB costs.
■1.3 Finished Hole Sizes All finish hole size requirements provided within this document are based on testing completed in FR-4 laminate.
