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

What do you mean the bga removal process can be manipulated by the operator?

AF, Buddy: I know someone "set you up" to ask this question, but: 1 What kind of "thermal excursions" are you interested in? Solder cycles, rework cycles, thermal shock, thermal cycling ... 2 What are you talking about boards, components, assembl

Does anyone have any experience with regards to reworking thru-hole ceramic capacitor D.I.L , taking into acount thermal considerations associated with these packages. The reason we are having to rework is because the device is wavesoldered on a th

In general, no. If you've got the right BGA rework equipment, you should be able to locally heat the part area that you're reworking. Though, if you're finding defects related to thermal stress, it might not be a bad idea to pre-heat the rest of th

| Does anyone have any experiences with bga reballing. | When I had reworked failed bga part with new part It was good. | So I tried to reball bga detached but failed . | I guess the cause of fail is thermal shock. | IS IT OK TO REBALL BGA PARTS
