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

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

Ahh, yes. Just about the same time you replied someone else I asked said the same thing! I didn't realize that you had to put the part on by hand for the vision test. In the book it says to leave the feeder position set to the default setting. Fu

I have been using my topaz X for about 4 years now and I feel that I am fairly knowledgeable about it, at least the functions of it that I use... I am trying to use the LCS to place some qfp chips on a new product and I have set the whole thing up t

I don't want to throw a spanner in the works here, but a large proportion of chip resistors & capacitors have been ROHS compliant for a couple of years now, the manufacturers have just not declaired it. Could it be that the part you have just has

Make sure that you have some feature on the part to get orientation check. We tried long time ago and it did work on GSM with 4 spindle. For us, setup the vision system was the challenge for correct rotation using vib feeder.

Well, I'm not sure about the "Trust me" button. I assume you can't tell it the part is smaller than it is because then vision won't accept it. I often add 10mm or so in X direction. In fact, when I measure the board, I just round the X up, becaus

Yes the components are flat and no larger than 50mm in size. Most are full rings or just an arc of a ring. I understand fully the best way to have the capabilities proven would be to have the vendor demonstrate. I am kind of looking at what people

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

We currently have a problem with our Universal GSM 2. A part ins presented to the front or back camera but there is no image of the component. Just a dark screen, even though the light system is working. Any ideas on what the problem may be? I suspec
