This is what I have come across with some of the gerber datas. Most CAD/Gerbers don't carry the fiducials because some of my customers don't have them as a standard but when the board house gets it they are the ones adding the fiducials. So send in a

I don't use the machines you have; I'm running a Siemens line. Regarding fiducials, this data should be provided by the design engineers through some kind of mechanical drawings. I usually get this with the CAD data. I don't know if there is a standa

Beats me. I thought you said "We are seeing a haze left behind on our current cleaners." I don't even know why you need to clean fids. [Are you scrubbing each fid to make it bright and shiney? What's on them? Why are you doing this?][I'm sorry I

How does a fiducial work? I am going to venture a guess as how it ralates to the parts you are trying to place... A PCB fiducial is a landmark. The fiducial tells the machine where the board is located in the machine. A single fid can only deter

What are some cleaning options? Or is it a camera issue? Not all our boards need the fiducials cleaned so it is hard to tell.

How well should the fiducial be centered in the teach mode? Consider that you see the fiducial with probably 40 times magnification on the monitor. If you see the cross-hair a bit off center, then this is most likely just by a few hundreds of a milli

To clean up other replys I will add that some most all machines have global correction. Most placements are an off sets from pcb 0,0 usually the lower left corner of the board. When the machine locates the fiduitals and these fids are not exactly whe
