I think I have the vision problems figured out. There were two problems. 1) The Alignment type was set to "Small" for my TQFP48 part. It should have been set to "Complete". This is a clear case of poor documentation. The AutoProgram manual lists the

Hello, can you help please with a question regarding Fuji NXT programming? During the placement of the components on the fuji interface the image of the components during alignement can be seen on the Fuji operator interface. My question is can be al

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

Does anyone know how to make the vision alignment work on a Quad 4C? What I mean is make it work right, and reliably. I know how to define the component for inspection (lead pitch, lead count, dimensions, tolerances, etc.), and I know how to set ligh

Hi, Can somebody tell if for melf components the x and z sizes are the same? Normally they are, but the machine's vision system sees only 60-70% of the x size due to light dispersion. The Z dimension has to be the one measured with a vernier caliper?

I've used an on-axis camera lighting for other components with a good deal of success. (But not for CGA's in particular) I would think it should work pretty well for a CGA application. I've done some pretty odd looking parts with this type of lightin

I have not placed these parts in a while but when I did Universal was the machine that did it. We were able to place these parts using a 1mil flat( upward looking camera) inspecting all columns. The problem is a 100% column recognition is not possibl

Sounds like the vision is having trouble deciphering what is the component and what is the background. The problem is what if the plating is inconsistent (sounds like it is)? In this case with front (reflective) lighting the problem may never be so
