BGA's are not difficult, but should be inspected no matter how careful you are. Here we have been doing bga's forever and x-ray 100%. Without an x-ray there is no good way to ensure the BGA is placed properly, without bridging or insufficients. If yo

We have found a significant number of PBGA problems associated with physical deformation of the package. Deformations such as dishing (potatoe chipping) and delamination under the die (popcorning). These can be detected by x-ray by the variation patt

Dave; See my answer to "Alternate to X-ray" The combination of endoscope optical inspection with x-ray inspection provides the most effective means of BGA inspection. Transmission x-ray provides a very rapid means of qualifying then process control o

Greg, Check out Circuit Technology Center in Haverhill MA. We have 3 Air Vac BGA Rework systems and 1 Nicolet X-ray system. We offer either\or BGA rework services and X-Ray services. You can get a little more info at http://www.circuitnet.com/cat

There is no question but that x-radiation is an ionizing radiation and can effect components sensitive to ionization . The higher the power level of the x-ray source, the higher the amount of ionization taking place. At low levels of x-ray we have ne

Does anyone have an example of an electronics X-ray quality procedure? We are implementing a new X-ray machine and it is my responsibility to compose the quality procedure. I know that each state has it own set of regulations, I am just curious to se

Hi, We place BGA, but until now have not used X-Ray inspection, and it would be a good thing to have. Can anyone recommend a low cost X-Ray that would get us by. We don't need something fast, but it should be able to show us clearly voids etc. Reg

Get a demonstration, on most packages these systems can see down a row. You don't see solder flux residue with X-Ray. You don't see the intermettalic bond with x-ray. They are some what expensive but together with X-ray you have an excellent quality
