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

Does your machine have pattern recognition, so you can program a corner of a trace, or some other unique feature of the board?

| In past PCB designs I have cleared all traces from all layers | (except pwr/gnd) from fiducial area. It has come to my attention that this is only necessary on the side where fud is placed. Which is the correct method of design using a fidicial?

I am not completely sure why it would tell you "board will not be populated" and then build it anyway, but if the only difference between the two programs (working one, not working one) is the fiducials are smaller, did you try reducing the search ar

We've been using fids as badmarks on panelized boards, with reverse recognition so that an uncovered fiducial is a good mark. It's worked fine with 1.5mm fiducials but now we've run into problems with a board with 1mm fids and we can NOT get it to wo

I am using a search area of 2.5mm and I use a Red dot sticker to cover up board fids to not be built. I have it set to reflect. threshold is around 100 but that could be different depending on what you are using to cover up your fiducials with. I w

Local fiducials will help component placement but will have no effect on part recognition. Local fiducials help you compensate for board skew or streatch by looking at a small area of the board vs. the board fiducials that cover placement over the e

Looking for any insight into whether the use of local fiducials will help or eliminate component recognition issues.

8" ). For calculation of the theta angle, the global fiducials should be placed over the diagonal. Component recognition can be improved if your vision system has different light zones. The steep light should be turned off and the flat light turned

Greg, Need to give more to get more! What are the details? What are the problems you are seeing exactly? What type of part are you trying to place? What type of machine are you using? What type of vision recognition? What type of PCB finish? Phil
