This BGA could have gone through the reflow cycle two times as we understand from the BGA manufacturer, during the BGA ball attachment process. (If any ball is found missing, they replace the missed ball manually after applying flux manually and refl

I need to know the advantages or disavantages of a plastic or FR4/Flex based BGA over the ceramic based BGA. We have a BGA package we are going to have produced. Some want to have it made out of ceramic because they feel a ceramic package will be a

We are not into BGA Tech (yet !), but I was discussing other issues with a knowledgable individual, who said that they do not reball BGA's. What they do, is to have a piece of glass, apply some flux to the glass and then drag the BGA across the glas

I am beginer in BGA assembly and am confused in selection of pick and place option. As per book on 'implementation of BGA Technology-by 1995 aeic inc. states that BGAs reflow is quite forgiving and you need only Mechanical centering of PBGAs. The IPC
