Welcome to SMTnet. The previous poster is correct. For more, look in the �Terms & Definitions� in the SMTnet Library. Also, search the archives for some sources of information [eg, magazines, organizations, booiks, training, etc] to help in unders

You mentioned a few specific machines that this technology is working with now. Which have had the best results? Which have experienced problems and what were they? What changes are planned for the ones in current use if any? Thanks

Search the fine SMTnet Archives, for instance � square and aperture � [http://www.smtnet.com/Forums/index.cfm?fuseaction=search_results&CFApp=1] will get you started on various pitches of uBGA [wid a cuppla CSP thrown in for yucks].

Multitronics machines, in their lastest incarnation, previously were Dynapert machines. A largely UK phenomenon. It's unclear that Multitromics made much US market penitration since their acquistion of Dynapert a couple of years ago.

It's amazing the eclectic applications that Silly Putty works for, what the heck, give it a shot! One question, seriously, what are the QFP dimensions? x, y, z? can you stand for the injected material to flow past the leads?

The material has to be injected from beneath the component, it's a 240 pin QFP, ideally I wouldn't want the material gong past teh leads as I have to have the option to rework the thing if, perish the thought, it fail's and need's fixed.....
