Ian, wasn't he also adamant that flip-chip is the future a couple of years ago? But he may have learned since then. :) 
  From the K&S flip chip web site description you wouldn't think they're trying to sell it. kns.com
  The Flip Chip Revolution
  According to TechSearch International Inc., the market for solder bump devices, including wafer level packages, will approach 10 billion units in 2005. The accelerating growth of flip chip technology, coupled with the growth of chip size packages, drives the need for increased contract bumping services.
