Do the dendritic growths not require moisture? Effect of radiation on the
performance of the circuit should be a concern in space.

        Dear Experts:

        I've been asked to investigate this concern, so here goes:

        When someone in my company mentioning using BGAs for a space
application, one
        of our customers raised a concern about dendrite growth.
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.
