I assume that you are not that impressed with the platform then? From the lack information out there I assumed that either no one has one or there are no problems with them. Also anyone had experience with CLi feeders? Again, not much informatio

What is the real problem? No-solder can mean a variety of things. No-solder due to lack of paste? No wetting to the part? Co-planer part? Please specify......

IPC-6012 Table 3-2. States "Fused tin-lead or solder coat - Coverage and Solderable". The lack of any specific dimension criteria doesn't make this any less a requirement. There must be complete coverage of solder on the land, and it must be wettable

We do not have capabilities with our current PCB layout software to generate a pick and place file and/or centroid data. Consequently, we are teaching all centroids at the machine. Are there any software tools or utilities that can take a basic ger

Yes, but no guarantee of solderability. This just puts more paste on the pads. From my experience, unsoldered QFN parts are not due to lack of solder, but reflow.

I do not have the warm and fuzzy feel about these coatings due to the lack of supporting data. Aside from trying to save some money on wiper paper I do not see an advantage that would justify it.
