It sounds like 3D imaging is much better at fault detection for partially visible leads like SOJ packages. Can any of the 2D systems actually do a solderjoint inspection on the outer rows of BGAs or is the angle too acute to accurately look at these.

Hmmmmm........I am thinking!!!!! Cleaning is the final process in our situation. After cleaning we have no need for the fiducials. Is the haze causing fiducial recognition problems? Ideally what you are looking for is a contrast between fiducial and

Dave: You pose a very good question. We have been in the electronics x-ray inspection business for 18-1/2 years and, to date, we have not received a single report of damage associated with x-ray exposure. However... we do see signs of long term x-ra

We are experiencing 2%+ dropout on one particular SOT23 device. This seems to occur during the actual pickup phase. I have made sure that my pickup position and height are correct. If I single step through the forward feed of the component, viewing i

| In past PCB designs I have cleared all traces from all layers | (except pwr/gnd) from fiducial area. It has come to my attention that this is only necessary on the side where fud is placed. Which is the correct method of design using a fidicial?

I am currently sourcing equipment to mount CSP devices. I have looked at the GSM Flexjet & also the Siemens 80 F series. However these machines only look for ball presence not ball deformation. Panasonic are the only ones who have a 3-D camera capabl

Can anyone give me information about a NCC8 (?) head for the Universal GSM's. Thats the one w/ four spindles and onboard vision (not flex jet however). Are there any maintenance issues with this style head? Is the onboard camera system accurate? How

| Does anyone out there have any pictures (jpeg preferred) of solder paste prints - or know where some are available. It will be awhile before our 35mm camera for our 3D scope arrives and I need some for inspection criteria. I need the good, bad, and
