SEMINAR LEADER
Dr Kashmiri Mittal was associated wtih IBM Corporation from 1972 to 1994. He received his Ph D in Colloid Chemistry in 1970 from the University of Southern California. Prior to joining IBM in San Jose in 1972, he was with the Electrochemistry Laboratory of the University of Pennsylvania.

Dr Mittal has initiated, organised and chaired a number of very successful international symposia. He has edited 45 books and has published about 60 papers in the areas of surface and colloid chemistry, adhesion and polymers.

Dr Mittal has given many invited talks on the multifarious facets of surface science, particularly adhesion, on the invitation of various societies and organisations in many countries all over the world. He has taught short courses on adhesion in the United States as well as countries like Brazil, Sweden and The Netherlands

The seminar is targetted at engineers and technologists from the following industries:
o PCB /PCBA
o Ceramics
o Metal Fabrication
o Plastics
o Disk Drive

Cleaning Methods - Found Interesing Article

Cleaning Carbon Dioxide is a problem - but there are some solutions:

Whichever process is used, cleaning depends on either the liquid carbon dioxide solvent properties, the energy and momentum transfer by the impacting solid phase, or a combination of solvent properties and momentum or energy transfer. Pellet systems rely upon the thermo-mechanical impact stresses related to the high impact velocity of macroscopic pellets for contamination removal - a momentum and energy transfer process. Snow sprays rely upon a combination of solvent action of liquid CO2 and the momentum transfer of high velocity microscopic snow particles. The liquid based CO2 washing systems rely upon the liquid phase solvent properties. Finally, the SFC systems rely exclusively upon carbon dioxide's unique supercritical fluid properties.
