Yannick, If we leave the 201 issue aside; have you checked where those BGA pads are connected to? Could those be power/ground balls connected to large (difficult to heat up) planes by any chance? Erhan

All, What if BGA solder crack do exist after the shock test? Its happen at the corner of the BGA. Base on your experience, what are the potential root causes? Thanks, Sean

Does anyone know of a freely-available document which discusses the main considerations of BGA assembly and inspection (x-ray?). l need to know about pad sizes and inspection standards and when to underfill and when not to etc.. l am looking at ass

We've had much trouble with flex circuits. As previously mentioned, you must have local fids for the board or the BGA itself (if panelized). Other troubles we experience are drilled holes for pinned connectors. Unless the PCB manufactur has some w

I am to implement PBGA, and i am looking for PCB surface finish informations. A lot of technical reports are specifing NiAu finishing because of flatness property. Because of leads shape, I though that BGA doesn't need flat pads like QFP. Is it false
