Griinder, Maybe it's me, but I think what you might be saying here is that you see a reflected image of the PCB or Stencil when you and teaching the fiducials and it is interfering with the teaching routine, is that correct? If this is true it is c

You are having problems with the PEC (fid. recognition, etc.) camera, correct? Not that camera(s) on the base machine (2.6 mil, 4.0 mil, etc.). If it is the PEC camera you are talking about I don't know much but if it's one of the other cameras I m

I clean all fids with a fiberglass brush pencil so that I know there will be no rejects (it doesn't take too long). The problem is the machine lighting. My Essemtec machine uses a light ring (red LEDs) around the cam. Here's one of many documents th

hi, We have a strange issue with a DEK 265 Lt, it powers up and initialises fine. Camera LED`s flash, cognex card intitialises with no error. The issue is we have no fiducial recognition or image on the monitor. Have swapped out camera, cogn

Leave a circular area around the fiducial without any mask so bare board is shown.

We are getting more and more customers wanting LED boards built on White Solder Mask. Well our printers do not get as much contrast between the white mask and the plated fiducial pad, and often the camera only sees white. Other than playing with

You stated, "The larger the fid dia, lesser is the accuracy during recognition." I don't necessarily disagree as far as the positioning of the fiducial in relation to the camera. In fact, I believe this to be the case and with a perfect fid, this i

Actually I considered that, but I was thinking to leave the fiducial pad bare copper. These are customer supplied boards, but hopefully they will be willing to make the change for the next spin. Any tricks for getting it to see the boards we alre

I grabbed another White board that does have the "natural" board around the fiducials. Still no go. See pictures

Hmmmmm........I am thinking!!!!! Cleaning is the final process in our situation. After cleaning we have no need for the fiducials. Is the haze causing fiducial recognition problems? Ideally what you are looking for is a contrast between fiducial and
