Is there any info, guidelines or spec's on how many time you can rework a bga location?

First, this is a very interesting question. Second, there is no specification. Third, companies develop guidelines for rework based on their expectations for their product reliability. Things to consider are: * Motorola allows no product shipments

Hi PeteB... I dont think you will find any Specs...but that I do not know. What I do know is it depends on the make up of your PCB and Components. Obvious haveing components that may be sensitive to heat the less you want to run or pass through. Re

Greetings, Is there a Mil Spec or IPC spec on how many times you can wave solder a PCB? I did a search on this forum with no results. Common sense says two or three times. I need documentation.Thanks for any info.

Hi PeteB Do you know PeteC? Anyway, it all depends on your most sensitive part. Look up the spec sheets to determine. Most general parts can take 3 or 4 heat cycles easily.

How many times can a populated board been reworked? What can go wrong (reliability) if the populated board is reworked more than 4 times?

We do not have any electrolytic capacitors on this board.

I'd be more concerned with the pcb itself then I would be with standard SMT components. Are you using a PCB with a high Tg? (170 degrees C or greater)

Also consider electroltyics as some brands can only cope with one pass through reflow, 2 max. In Vapor phase 1 pass max is typical. Although depends on makers specs and what they say the device can withstand. main issue is Dielectrics get damaged , c
