I would also "nice to have" because of your process. Inspecting solder paste from a 2D point of view manually would not assure you quality if the paste is 75% off pad. Plus hand placing onto solder paste causes it's own set of problems which will c

The 5 thou standoff of your SOIC is probably the minimum. We wouldn't be surprised to see 10 thou. With this, you could have maybe a 6 thou gap between printed solder paste and the bottom of the heat slug. So, you're expecting the rabbit ears of p

Thanks for the info. In a past life I ran everything WS and washed in a batch wash using saponifier. I'm surprised I never saw anything then as we would regularly wash boards assembled on only one side. Unless it's specifically washing in DI only.

Has anyone heard of an AOI manufacturer by the name of SVS? They may concentrate on solder paste inspection and not 'true' AOI. Any information would be helpful.

On a related note...... I'm wondering if anyone has any experience with 3D inline solder paste inspection systems. I've read about all the features and what they are "supposed" to do. What are the real-world capabilities of these machines?

We are considering the CyberOptics SE300 for solder paste inspection at post-stencil print. Does anyone have experience with this AOI machine? How it works with small apertures like 0201's and uBGA's? Comments are welcome. Thanks

Thanks for your input. Where do I get information about fiducial dimension? Also is there any IPC standard for SMT process?

Try: * IPC-2221, 5.4.3 Datum Features * http://www-ese.fnal.gov/ese-dfe/SMEMA%20fiducial%20mark%20standard.pdf

JJB, Which machine are you using? How involved is the programming? Is it a 3D system? Many questions. Thanks Chris

We have an Agilent SP50 system. It is a 3-D system. The programming is pretty simple relative to some of the other machines we evaluated.
