Hi, you can do it using Cadence and it's subprograms or you could find someone with ownmade convertor(there are a lot of people who work om the problem last years.I know 2-3 and if I find some of them I'll give you their coordinates.

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

Can someone who has experience with the above share his knowledge in programming the X-Y coordinates, is it in text format, .csv etc? What's the structure of the program in columns(e.g Description, Part No., X,Y,R)? Is the "FlexProg.exe" program com

Bent nozzle can result in vaccum leakage resulting in parts falling during part pick up. Correct this. However, if your machine has laser/vision alignment, you should not be having a problem since these come in to picture after pick up. If you have a

Check flux penetration and type of flux. How much is solid contents. The solder filling is better under Nitrogen. Check the time (speed) of the nozzle whether is correct. Usually For SAC305 the temperature of bath is 320C/degrees, but only for sel

there is manual method of doing it you download GC prevue which you will able to open up the gerber once you have imported your gerber you can select a reference point and press Z on your keyboard and then you can go to each of the component and wr

Maybe I'm missing something here (we don't use locals and have never found them to be helpful, Panasonic and Fuji) but the fid coordinates don't necessarily have to be the same position in relation to the part placed. If you can use global fids. (whi

I know that on Philips Topaz equipment you can define the XY locations of the individual local fids relative to the mount-center of the component that they apply to. So if they are not symmetrical w.r.t. to the QFP's center there's no harm done. You

If your boards are not totally rectangular part of the board can stick out past the stopper. If the fiducial is there then you can't use it. Also make sure you are not using panel fiducial co-ordinates and then expanding those out with panelization

If the machine or machines couldn't recognize the fiducials, you can grind it with a fiberglass eraser. If the fiducial are missing you can use tooling holes, and/or via holes. You can verify the hole size and tolerance on the PCB assembly drawing.
