Mark, The 10011 and all other process types are hard coded by Contact Systems and can not be changed by the user. The user can, however, change the Vision Center Type information as well as the Vision Size Code. Our Center Type for SOT23 is: Process Type: 10011; Edge Threshold: 23; Intensity Threshold: 75; Offset: 165; Gain: 16 These numbers might be slightly different from your numbers, and it is important not to change them unless you are making global changes to the Center Type parameters. If you change just one of the numbers for the SOT23 part type, the machine will not place any other parts at the same time, due to different camera settings.
That said, if you look down into the tape loaded into the feeder, the single leg side of the SOT23 should be towards the tape locating fingers. This is "Zero" orientation. When the part flys across the camera you are seeing the legs out the left and right side, correct? This, opposed to legs up and down on the screen. Please post the actual error code you are getting.
Also, are the Contact machines new to you, or are you experienced with this sort of thing and just stumped on this particular part?
