HDI BGA breakouts and routing strategies

This abstract for the webinar on new HDI BGA breakouts and routing strategies was written by Happy Holden:

Although we have been using BGAs for 20 years now, the breakout and routing of them on PCBs has not changed a lot. High-density interconnects and now Ultra-HDI offers alternative strategies that can improve how we route large or fine-pitch BGAs to achieve lower costs, higher performance, or improved reliability. This talk will highlight some of the new techniques and strategies that have been developed for designers that you might not be familiar with.


What you will learn:

  • Four strategies developed in Europe and Asia
    • Vertical Conductive Structures (VeCS) – A true 3D structure to replace HDI (at lower costs) or with HDI to achieve higher performance
    • Integrated Mesh Power Systems (IMPS) – A novel routing structure for high-speed circuitry of only two-metal layers
    • Power Mesh for PCBs – An application of IMPS that requires four-layers but is faster and suitable for very high-speed applications
    • Channel routing – Taking advantage of chip pin assignments or pin allocations in FPGAs
  • Swing via breakouts only practical with HDI
  • General advice on routing strategies from Sierra
  • Appendix of useful tools
