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

I agree with PR. We run down to 12 mil pitch with out local fids. We run with 2 global fids for a panel of up to 40 boards. This has worked very well for us. Jerry

It depends on whether the Fiducials are Circuit Fiducials (located on the PCB) or Block Fiducials (located on the Panel) His way would be for Block Fiducials.

My steps are different in that case: 1- Check mounts. Try to adjust origin point until get the pretty good mount positions. 2- Teach fiducials ( Board fids, not panel fids) 3- Use fids, check mount again. 4- If OK, then teach Block Repeat. This alwas

I rarely use blk fiducials. But when I do, they are always programmed after the fids. It's the fids that sets your general alignment of the panel. I only use blk fidus for thin pcbs (30 mil) that tend to warp when on the conveyor.

You would be better off setting a new fiducial using a pad or other feature that would serve that purpose. If the board has not etched correctly, it is better to bad mark it and not use that board on a panel. Safer in the long run as it may have othe

We just got our used Fuji IP-1 working well. Sometimes during testing of a new program/pcb we like to stop the run and re-start with a clean board. When we make the IP-1 eject the unfinished pcb and start with a new pcb the IP-1 does not scan the f

Is it good practice to use a PCB mechanical drill hole as local fiducial? Would it increase my placement accuracy? Or should I stick to my panel fiducials? We're using a panel with 4 boards and we're trying to reach a 50 microns accuracy.

you can copy board at the panelize option and put the value of width of the first board at y of the second board. use panel fiducial at the mark coordinates

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
