NEITHER AXI nor AOI are "stable" or "repeatable." If your false call rate is zero, then you've basically rendered the machine an expensive conveyor (ie it's passing everything 'cause you've opened the limits too much). You can *try* to do a Cpk or

You are correct. There is an option under Generate Program to Breakup program For Separate Central controllers. I choose this option and then it asks for a suffix to add to the program name. I am using Head as the suffix. After program generation I s

For lack of a better description, we'd say, "Yes, that could be corrosion." Regardless of what you call it, it looks nasty and should not be allowed on bare boards of any sort. Based on your picture, we can't tell you whether it's related to your con

Hi George, I would suggest you to re-look your process parameters, especially for the pre-heat temperatures and the amount of flux deposited. The mask properties and that of your flux also play a role, but you could zero down to the root cause after

Try: acrylic adhesive Klapton tape [google for a source] It too is more expensive than the silicone adhesive tape. So, your buyer will keep trying to sneak the cheapo stuff in on you. We had to write a procurement specification and they still wont q

I think you are too hot out of the gate as well as too slow on conveyor. I think settings similar to 130, 140, 150, 160, 230, 240, 260 and conveyor speed at about 28 or 29 IPM would be more realistic but it depends on your paste and oven config/zone

According to 5.2.6.1, it states that defected if Solder balls are not entrapped in no-clean residue or conformal coating. How do you define entrapment or how do you assess if the balls won't dislodge under normal product service environment? The sold

I have noticed this on some of our large multi-circuit panels. It's such a slight rise in our false call rate that I haven't really explored it. I'm just guessing that it has something to do with the fiducials calculating the twist/shrink of the boar

We have recently installed a selective solder machine that is running SN100C alloy. Based on the fact that the pot maintenance is done inside the equipment where adequate ventilation is present and we aren't dealing with lead, I don't see the need f
