We have in our Co. an used My Data SMT (Version 2.5.4d) machine but we have a problem. After creating the file we import with a flash drive.We load and set the two fiducials and after everything is done we try to EXPORT the PCB file instead of being

Put anything over one of the fiducials being used in the circuit, and run the board. It will stop, and on the top right a window will pop up. Click "Skip Current Module" and it will X-out that circuit. If you are using the fiducials on the rail, rath

I don't think there is anything releated to IR light in your false calls rate rise on Post-reflow. Soldering Flux is most probably the reason. Indeed, more or less soldering flux residue condenses on the boards according to the oven extraction syst

I don't think that there is an industry standard on that. Each machine manufacturer will have to say what they mean. I think the first option looks at what you taught and then looks at what it sees when looking for the fiducial. The other method sou

I agree with this post about new and standard component names. Standard components should not be changed outside of perhaps widening the tolerance to accept poorly produced components. By purchasing poor quality/cheep components your purchasing depar

We don't use flex pcbs but have the same issue here. Most of our pcbs are HASL finish. I have looked at silver and gold immersion and both look really good under my color camera on my AOI. However, gold is more pricey. There is no additional cost

We used durastone pallets, where you mill out the profile of the panel or board and it sits flat for printing. We secured them using 3M spray mount (for singled sided) and Kapton tape. Obviously helps to have bottom side heating in the oven as you

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

John, contemporary machines provide their own software for programming - most you can do completely offline. There are several tricks here: 1. Design libraries correctly - you should have polarity convention that matches your P&P and your AOI machi

Our company has a process standard that requires a double person check at the beginning of every run (size of run is irrelevent, whether 20 panels or 500 panels). Every changeover that occurs a first piece inspection is made before reflow. If all is
