Hi There, Could someone please point me in the right direction in the subject of baking 'metal' packaged BGAs before rework. What are recommended baking temp. & time. Much appreciated. Jack

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

Much of the ability to survive rework or thermal excursions is dependent upon the fabrication materials. The board qualification criteria under the 55110 was designed around 5 thermal heat cycles. Consider reworking a BGA in this context. BGA i

Dear SMTneter, I am loonkig for some information about how to rework a BGA. Some technical info explaing how to put solder past manualy, soldering manualy, tips and so on. Where can I find something about? Thanks in advance Marcos

Hi Marcos, If you need more information, I have a couple of books introducing and reworking BGA's. Details can be found at:- www.abtech-europe.com/smt/publications/prrsfpb. Barry

Hi Barry, didn�t get very useful information regarding the problem of BGA rework with your link. Are you sure you gave adequate technical advice ? Hope you�re not only trying to sell books. Wolfgang

Gentlmen, Thanks for the information. I am sure that I have some sources to star to study now!. Acctualy the volume of rework is not so much, but as we perform repairing in electronic baords, we try to work properly even in few repairing. Thanks aga

Can I then say that in general boards are not encourage to rework more than 3 times since the boards will be subjected to Top and Bottom reflow? What is 55110?

That's what we do [no more than three reworks or mods]. Your "four reworks permissable" was probably based on the 55110 five thermal cycles, counting wave soldering as the first cycle. How do you plan to keep track of each of those rework actions?
