In trying to have things run smoothly with placement, I have to do a lot of theta adjustment to get the rotation right during placement. Even if the part looks good on the PnP machine screen sometimes it places differently than what is shown. If I u

rotation reset. That engineers actually do this just proves to me what a mischievious bunch of "little minxes" they really are. What I do is pick a package and >select>same pattern>same rotation. Go through 0,180,-90,90 and check for each pattern. Th

Genny you are right on with the differences between suppliers/packaging etc... I am a CEM and you are correct that we pay no heed to cad rotations from our customers/designers. A.V.L./manufacturers P/Ns information specifies orientations and such.

I don't have CircuitCam, I'm using Unicam with Mydata. In Unicam I have a Theta Offset setting for each package witch determines the default rotational angle with respect to the pin 1 setting within the package data. With Mydata, the package inform

I do not know what software version you have, but on older versions it is best to have a mounting inspector set to be the primary and then mask out all labels and solder so it just locates the part. Then add another mounting inspector for looking at

Ron, I too use a Nicolet NXR 1400i. By using the rotation fixture and offsetting the board, a good BGA solder joint will appear elongated. If you rotate the board away from you the wetted joint will appear to lighten and become flat (looking at the

Another question about Set Command Variables. We use fixed dimension, multiple window PCBs in all of our UIC machines. It is often required that we use the rotary table to populate the entire panel, but this means that for each rotation, either the w

Hi Jerry, Thanks for coming to my aid again. I have tried your settings of 10% for Lead check and pitch limit but still rejects the part. The vision image looks clean on the display. On one of the last trials I noticed that the part was picked up

I have a CP642E machine that will not function if auto adjust is enabled in Part Descriptor. Symptom: Auto pick offset causes machine to pick part off center to the point of going to end of part after several picks. This only happens to parts that ha
