Do BGA packages absorb moisture to a great extent if kept exposed to an atmosphere of 300C and 60% relative humidity overnight? Should they be backed before reuse. How long can they be kept exposed without the requirement of baking. Are there any spe

Trying to come up with a way to repair or replace damaged or missing balls on BGA's. Has anyone done or tried to do this?

Does anyone have any data about the dangers of reflowing BGA's twice? I have a customer that is concearned about cracking in the intermetallic layer after the second pass. Thanks in advance.

Aperture size should vary with the component [pitch]. That size should be the same a the pad size. So, generally pinching is not required. Indium discusses BGA apertures on their site [ http://www.indium.com ]
