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.

Components do not have to be in the framework of the fiducials. It is recommended that the fiducials are at the outer extremeties in at least 3 corners of the assembly however. It is also a good idea to keep a minimum "keepout" area around them of

Hi Jax, The alignment pop up only on some parts and it's random axes. This happens every prototype run that I need to adjust the alignment of some parts. Fiducials are correct and okay. Also had done calibration on our machines. I really suspect that

Are you sure it was measuring a fid? Is it possible it was measuring a block-skip mark?

Use a circle 40-50 mils. Via's and silkscreen layer markings are inaccurate.

We use an EKRA E4 printer, but the concept sounds the same as far as the fiducial alignment goes. I have found that SOT-23 components work the best for fiducials - and I always make it a point to use them on our older PCB's (where the screens do not

Offsets are there to for an alignment change over the entire board... alignment weighting is, essentially to account for imperfect match between stencil and board, and will allow you to concentrate best alignment to a given portion of the board (give

| Here is my question. We have several fuji CP's in our shop, every once in a while the first couple of parts placed are off the pads. When we move the parts further down in the sequence they are fine. What is going on? Has anyone had this problem an
