Rick,
Reference IPC-A-610C section 6.5.3.1 Figure 6-44 makes diameter
reference to maximum allowable solder ball.

Subject: [TN] Allowable solder balls on a component?
What is the largest solder ball I am allowed that would not violate
minimum electrical clearance?
I am working within class 3 requirements. The component in question has
9.6mm spacing from the edge of one pad to another. Eventually this
assembly will be conformally coated.
I've turned to A-610, section 12.4.10 but it presents me with this
"minimum electrical clearance" question, and it's appendix 1 doesn't
seem to be of much help.
Any thoughts would be truly appreciated.
