Case study 1020 node board 310 beads - mostly on DDR lines Increased access by 30.4% ! Lead-free / no-clean Good contact : pin test 99.5% ICT overall yield : 93% Group/Presentation Title Agilent Restricted Month ##, 200X
Bead Probe Song ! “Just Bead It” - Credit: Brad Jolly (Apologies: Michael Jackson) They say that access will be going away We need a new technology to save the day So open up the trace and let solder flow away Just bead it Just bead it Bead it! Bead it! Put down solder paste and heat it! Make a big target – easy to hit Look at the increased coverage you’ll get Just bead it! Just bead it!
