I found a different one called "e810007b.pdf". Its 900K and has info on all the things mentioned in previous posts. I went to the japenese hitachi site at www.hitachi.co.jp and selected the english language pages then products / semiconductors. It was listed on the main section in a list of new items. I couldnt seem to get a connection to the US hitachi server. Anyone with the larger file care to tell what the differences are between the 2 (I have never done any smt so I would really like the most useful version) Phil col.priest@bigfoot.com
