Here are links to the web sites for three instruments specifcally designed to monitor wave solder process. Some have SPC logging capabilities: http://www.ecd.com/emfg/instruments/waverider/ http://www.swpc.co.il/wso.htm http://www.solderstar.com/w

Sorry to nitpick, but counting and responding to the number of defects isn't process control. It's done all the time, but it doesn't really fit the definition and that's what I think DB is trying to investigate.

HHmmmm!! looks like i'm getting it way wrong by wanting to chart the quality of product coming from my wave solder machine. could some of you let me know whats the best way to monitor quality on this process.

Thanks to all for the input. It has helped change our standard SPC program around. (To davef: Dad handled most of it, but Vegas got the rest)

It depends on how much paste you put on the pads. Assuming your stencil is 1:1 to the pad and the solderability protection on the board is something other than HASL, we'd guess that your solder height is approximately 50% of your stencil thickness,

If the users could change any thing on the MPM printers what would it be and why. thanks Harry

I would put the tactile sensor back in the Vacuum nest so operators won't drop it in the paste. my biggest wish, pr

Harry- Why don't you figure out a way to take the top tactile out and convert it to work in the nest....so people won't have to buy another one.

Here's an easy one. Make a camera that looks up at the board a non-mirror image. You could keep the mirror image toward the stencil since stencils rarely have any legend on em.

Ah...but if MPM didn't mark up their parts like they do then you would be still working for them as a field service guy....instead of remarketing parts and machines.
