My Quad IVc checks fiducials on the board, but only on the first board of the run. all subsequent boards are not checked. How do i change this so all boards are checked / aligned to their fiducials? The first board always comes out a bit better th

In the teach menu of Central controller and under Teach Board Fiducials there should be 6 options. Turn on Global Fiducial Correction by putting a Y in the box. Make sure all others including "Fiducial Data from Autoprogram" have an N in the box. Use

Can anyone tell me if they are aware of any pick and place machines that can use 'randomly placed' local fiducials? Now, let me explain... Our machines (Contact 3S, and 3AV machines) can use local fiducials in several ways. We can use a single center

We have a Quad QSV-1 and have had some trouble with it reading 0.040" fiducials. Our work is very low volume so we just manually spot the ones it can't read. We do not clean the fiducials. Instead we increased the fiducial size to 0.060" and it has b

You want your machine to spot the fiducials automatically. A 40mil round copper pad is the absolute minimum fiducial to use, but we found in practice that our Quad equipment won't spot them reliably. I am now using a 60mil round fiducial and it picks

Mikej, I'm only running a single image, just want to correct for the slight variations in how the board seats in the transport. It's not more than a few mils off, but enough to cause an issue on fine pitch parts. I don't have any image fiducial

The global or image fiducials is set under teach fiducials screen. You will get the option to turn on the one you want. You should choose one or the other depending on what you are building. You are correct for what tep hold,pass and tep vision does.
