Has anyone had any success in finding open circuits (i.e. ball present but not soldered to PCB) under collapsible BGA's using an Agilent HP5DX x-ray tester and the BGA2 algorithm? Can anyone recommend an elongated pad design which produces the neces

The 5DX weighs 8000 pounds. Can your product bear the overhead? We use acoustic microscopy to find BGA opens. We have not had good luck finding opens with other inspection technology. Has Agilent told you that you can detect BGA opens? How is th

Hi - I'm looking at 5DX as a method for inspecting BGA joints and would like to hear from anyone with knowledge of this system . Can you tell me how reliable you have found it to be in catching BGA opens ? ...... also any other comments you may have

Allow me a contrary viewpoint. I've had these things on my floor and had customers get outsourced evaluations done with them. Most expensive boat anchors I've run across. First the good points: The automated scanning and pattern recognition is go

Looks like an improvement to the spinning stuff, but gads, I wish these people would stop using the term slice. The Teradyne still does not create a slice. It infers things from different sized shadows. It still cannot actually image a slice thoug

Purely from a technical interchange perspective, how thick is a slice? That is, what is the Z axis resolution of the machine? This isn't listed on the web link. There are pictures that imply separate of a BGA on the top and discretes on the bottom

I would recommend looking at SAKI/MacroScience. http://www.xraytechnology.eu/index.php?option=com_content&task=view&id=34&Itemid=42 I have seen the images created by MSX3000 from MacroScience which is now under SAKI and can tell you with certainty

I think alot of those X-Ray machines out there "over-emphasize" BGA analysis. It'll measure every aspect of the BGA, like size of voids, percent voids, how many voids, cumulative sum of the voids, shape and geometry of voids, statistical distributio
