Has anyone in the industry had even a fair amount of success inspecting reflowed solder joints to IPC class 3 standards? I am not interested in hearing from system reps or people who work for an AOI manufacturer. Thanks,

90% of the assemblies our company produces are class 3 and we have no problem at all inspecting or getting class 3 quality through reflow. Rarely do we have touch up because of insufficient or poorly reflowed solder joints. What are the problems you

What does "maintain it really good" entail? For reference, this is our maintenance procedure for the FX-D: - At the end of an 8hr shift, the solder paste path is purged start-to-finish using Nordson's ValvePurge. The machine's then powered down and

Here's what I do: - Test Surface Insulation Resistance (we're in the high reliability market and use a test significantly harder than IPC's). I also test SIR in combination with other assembly materials like conformal coatings and wave solder flux
