Well I am sorry that you could not contact me directly but here is the
information on the video tapes, poster sets and all that good stuff. Also you
may be interested that I now have a Home Page which covers all the material plus
it provides new  FAQs on BGA, Reflow Soldeing and Temperature Profiling and
thats not all. If you need in-house training the standard courses are all
covered on the Home Page.
Finally i will be conducting two workshops and one PAC at Nepcon West so see you
at the show in the BIG ROOM.
