as long as you are not getting recognition errors, and placements look good, go with it. as far as the pattern matching, the only thing I can think of is changing the it from circle or square to sp. shape and giving it the dimension sizes asked for.

While I don't have a dog in this hunt (my only comment is that I wouldn't want to buy a candy bar that has been taste tested), I do very much appreciated the validation that I DID in fact retain something from college. "Granted, if I were still in c

Hey Patrick, thanks. The area that is dark (half circle) is where the camera was. It is the same color as the above. But you may be correct still. I also noticed that the majority of the solder balls were along the "Dark" blue depression around the

If the HASL was poor quality and very thin you would find this defect....but you would expect to see it on more pads also. Also, you'd expect to see your solder from your solder paste either dewetted on the pad or reflowed onto the BGA sphere making

In csae you use 2 fiducial recognition, ensure that board fiducials are oriented across a diagonal and spaced far apart. Also, maintain a prefered dia between 1-2 mm for the fiducial on board to have have a better correction factor recorded during fi

Reflowing a BGA can be a reliable and long term fix, but it has to be done correclty, and using a heat gun and going in circles around the part is definitly not the right way to do it. To do it correctly you would flux under the bga, use a rework st

The boards are being soldered in the wrong direction. Rotate them 90* and your problem will go away. To demonstrate this further, rotate the board 180* and observe that the problem moves to the opposite side of the connector. I assume that in the

It's a Spectrum Technologies Sienna 300 Series. The main down fall is that you can only program x and y (as far as I know). By that I mean you can't do circles or diagonals. Only squares and rectangles or shapes with only vertical and horizontal s

You need two calibration jigs to calibrate these cameras. There is an L-Type align offset jig that involves removing the front feeder base, and placing the target dot over the middle camera of your front camera bank. After this calibration is done, t
