Re: Extremely long subject line | 8 April, 1999

Bob,

Thank you for posting an extremely relevant technical question to the Forum. However, the entire message was posted in the subject line and the body was left blank. In the future, please use the subject line to summarize your message, and type as much as you need to in the body of the message. Extremely long subject lines only make the Forum harder to read and less useful. The Forum has plenty of traffic, so your message will most likely receive responses without posting the entire message in the subject.

Thanks again,

| I'm not sure about limits but perhaps underfilling the BGA might easy your mind. Treat the BGA as something similar to a flip chip and dispense underfill around the part. The rigidity gained by the cured underfill may be enough to alleviate some of the stresses.
