I am looking at the Pump application for several bottom side applications we have. They are heavy in through hole radial and dip content. The initial testing of the stencil was very good, but I am concerned with inspection of the glue. We do a sampli

Jason, In Transmission AXI the entire solder joint volume is imaged, not just a slice (no missing information) as with Cross-Section. Also, there is no signal loss from mechanical or digital image reconstruction (highest contrast and edge strength).

Is anyone out there using a "Opti-Check" system? I think it is distributed in the States by Mancorp. We are based in South Africa and have recently purchased this piece of equipment and would love to get into contact with others using it in order to

Pete, I have to disagree with your statement regarding 3D Xray not being a good source of determining solder volume. The Agilent 5DX is absolutely fantastic at determining volume. However, cost of the system makes it not very practical. Jason

Yes, there is a limitation with Transmission X-ray on double-side SMT boards, ie.: back-to-back solder joints, components on bttom side over a solder joint.

Yes, your "slice theory" is correct, but ask yourself "how many slices?" This is the trick. By adding "slice points", you increase the robustness of the image. At the same time, you add time to the scan. Not too much that it outweighs the benefits,

uV light inspection indicates the "completeness" of coverage, but provides no measurement of coating thickness.

Thanks for the suggestion, but on samsung's website, I only seem to see a paste inspection machine and not a post-reflow inspection machine. Does anyone have experience with the MVP or SAKI AOI machines?

I am looking for input on good blacklight to inspect silicon coating coverage on PCB's. This inspection is visual. Any advice or recommendations on lamps or bulbs?

| How are you inspecting pcbs post-reflow, are you inspecting all or sampling. The type of assembly involved would be mainly chip components with a mix of actives and a few 25mil and under pitch. | If you sample what are your fault rates looking lik
