Hi Paul, If you have the option than choose the package which your process can handle best. Handling a component in a process doesn't stop at SMA. Think of Inspection & Repair. You should be able to inspect and repair a board with a 0.5mm pitch BGA before allowing it on any design. Implementing BGA's in your process is a bit scary in the beginning, but the components are less susceptible to "handling-damage". Once the process is setup right you'll see less defects than with fine pitch QFP's. Hope this helps a little in making up your mind.

Now, for a new design, Engineering is giving me an option of a 64 pin BGA or QFP. Both have a pitch of 0.5mm; is the consensus to stick with the BGA? Are there any potential gotcha's?
