At times, yes. We do high volume, fine pitch on flex panels and if we need a 8 mil width aperture, it can't be 9 or 7. It has to be 8 and we have seen times where the tolerance is +/- 1 mil. Additionally, we have received stencils with abnormally

Where you inspect depends on what you're looking for. X-Ray is a fairly specialized piece of gear and doesn't lend itself for example to paste registration or thickness measurement. A laser system is better suited. An X-Ray system would allow you to

Clearly you are above liquidus for too long so you can either increase conveyor speed or lower some zone settings. With your current recipe you don't mention the conveyor speed or the total profile length. Also ...are your max / min slopes really so

We have Mydata and you can print a report telling you the average placement time per part number. I monitored a few months of jobs, broke things into package type, grouped packages with similiar times (such as chip components up to 1206, SO-8,14,16
