Patty "Micro sand blasting" refers to using a device related to a sand blaster, for the purpose of removing a coating. Typically used for removal of conformal coating, but it could be used for other things - say you want to take off some soldermask... Strictly speaking, not sand blasting as the media used is not sand - that would eat through a CCA pretty quick! If one was a lawyer one might say that it is another form of mechanical abrasion, but we won't get into that. And the author didn't mention the old "burn it off" method... There are several manufacturers of micro blasting equipment - check www.ccrco.com for one example. regards Graham Collins Process Engineer, Litton Systems Canada, Atlantic Facility (902) 873-2000 ext 6215 >>> [log in to unmask] 11/21/00 03:57PM >>> Technet colleagues, My boss came across the term "micro sand blasting" in an article in the April 2000 edition of SMT Magazine. He asked me what that was and of course I did not have an answer. Can someone give me a nice description of this operation or process? The article had to do with Conformal Coatings and the pertinent sentence was: "Rework on acrylics and urethanes can be handled using mechanical abrasion or micro sand blasting."
