Hi Jim, I'm no BGA expert, but I would think you would tend to experience dendrite growth on anything that doesn't get cleaned properly. Some people may have equated this to BGA's since it may be harder to clean thoroughly under some of them. I would thank that if you get the cleaning down pat, the dendrite thing would go away. Good luck in your new role. ; > ) Charlie B.

Unfortunately, this is the only information I have. I don't know any specifics regarding the assembly or the application (or the customer, for that matter) or where or what kind of dendrites. All I know is that I'm now deemed the "company expert" on BGAs, so I got the task. Has anyone heard of a dendrite growth problem associated with BGAs? Thanks for your help.
