M.L. Feather- You may be better off using a square (rectangle) SMT pad instead of a Router hole. Since all the placement data will be referenced off the "fid" you use - placement problems could happen if Router holes are used as the router path can v

It's obvious the problem is in the software. Because they tried to make it user friendly, you can't use the vision system at all. You only choose the type and everything else is done internal. that's why they missed some possibilites.I know mashines

I don't know how your printer could match the board's alignment to the stencil if they aren't. If you don't have fids on both board and stencil that match you'd have to use pads, but then you've got apertures thrown in to the mix. If that's the sit

Thanks for your help. I have resorted to using pads as the PCB doesn't have fids particularly close to the stencils fids. All previous jobs have had fids in the same place on the stencil as the PCB. The printer has a wiper paper which I have set to e

We've done many fine pitch parts using only global board fids with good results. However, if you're working with flex or flex/rigid designs, I would never use global or panel fids for fome pitch placement. We always request addition of local fids u

Does the board appear to be in the right possition on the conveyor when the camera comes to look at it?

Does anyone know why my MPM AP-27 machine would forget its fiducials? I make the program, save it, and then when I run the program it says it doesn't recognise the board even though I just taught it! Has anyone else had this type of problem or have a

I fear your files are not stored in the default directory or your hard drive is full. Boot with a DOS boot disc and check your C drive for program and fiducial information. Try an older program to check if the program structure and vision informatio

After the machine stops for any reason when restarted the z table goes to loader position comes up then goes back down and re-reads the fiducials, only one machine does this but we are losing valuable cycle time after every part change. We have Fuji

| Okay here is the deal. I am fairly new to the company here, but one thing I have noticed is that we read way to many fiducials, in my opinon anyway. One for example is this. One assembly was reading 17 fids. Smallest pitch was .25mil I say you
