Yes, your picture is correct. Regarding the dichroic mirrored prism assembly…in this application, a dichroic material is one which causes visible light to be split up into distinct beams of different wavelengths. The original meaning of dichroic, fro

The superior machines typically use only a split vision system which allows two pictures to be viewed simultaneously. The PCB (pads) and the underside (balls) of the BGA can be observed. By using micrometer screws, both exposures can be adjusted exac

One camera is used with typically one of the following prism set-ups: The split prism system, in its most common form, is a cube made from two triangular glass prisms which are glued together at their base using polyester, epoxy, or urethane-based ad

Thanks for the reply. So a mix of two images is made by optics(2 prisms) and ONE camera shows the result? Or there are two cameras and a mix of two images is made in video mixture device?

Not like that. Like this. The prism area is a partial mirror. A variable light source at Image 2 is key.

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

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

You are programing something wrong or your image is not in the center of the stencil. On DEK machines you can move a lot in Y by offseting the image in the program. In X machine can move +_5mm. Now, sometimes there is a way around this as well if yo

Have you measured and input the "Distance To Image" setting correctly? If that number is off, you will get that error.

Hi Printer is DEK265GS if I remember correctly. It is definitely not a programing problem, I have 15 different screens which I've checked and all are working fine. It is also not a problem with Y shift, as I've compensated it with CUSTOM SCREEN o
