Thanks Roberto, I have sent out about 100 copies of this presentation so far and its funny, there is such an outcry for information on this subject I expect we will have visitors from outside the San Diego area coming to listen to Tony Shoot talk about this subject of HDI and BGA routing strategies... I think he would be wise to present a longer presentation at one of the major events like PCB EAST or WEST or even one the Designers Symposiums... we are time limited at our DC meeting and can only have about an hour of presentation. I can recommend, if you are looking for more info on HDI, that the IPC publishes a very good design guide on the subject, IPC/JPCA-2315 Design Guide for High Density Interconnects (HDI) and Microvias. I recently purchased a copy after attending Mike Fitts class at PCB West on HDI and the benefits from the use of those guidelines... I found it very informative and eye opening and I can't wait to use the design rules on a potential board design in the near future... there are great cost advantages and space savings to the design technique....
