Up vision calibration

Best way to test this is to have a test PCB and parts at hand, like the demo PCB that came with the machine and a TQFP100 chip. Select either "Quick" or "Accurate" for vision mode and repeatedly place this part:

• part placed too far to the right?
  • increase X camera position
• part placed too far to the left?
  • decrease X camera position
• part placed too far to the back?
  • increase Y camera position
• part placed too far to the front?
  • decrease Y camera position
• part measurement width too high?
  • decrease "Distance/Pixel" X (first value)
• part measurement width too low?
  • increase "Distance/Pixel" X (first value)
• part measurement height too high?
  • decrease "Distance/Pixel" Y (second value)
• part measurement height too low?
  • increase "Distance/Pixel" Y (second value)

Nozzle calibration

"NozzleDown"

These values calibrate the 0mm depth, e.g. for the PCB this is the level of the PCB holder, the system will automatically add the PCB thickness

"Down To PCB"

1. manually move nozzle 1 over the PCB holder
2. click "Nozzle Down"
3. nozzle 1 should just touch the PCB holder
4. adjust Z value of "Down To PCB"
5. repeat from 2. until done, else click "Nozzle Up"

"Down To Stack"

1. manually move nozzle 1 over a pick position of a tape feeder stack (ideally no.1 of the left stack), no tape inserted
2. click "Nozzle Down"
3. nozzle 1 should just touch the metal surface of the pick position
4. adjust Z value of "Down To Stack"
5. repeat from 2. until done, else click "Nozzle Up"

"Down To Front"

1. manually move nozzle 1 over a pick position of the front IC stack, no part, just the bare stack where a part would sit
2. click "Nozzle Down"
3. nozzle 1 should just touch the metal surface of the pick position
4. adjust Z value of "Down To Stack"
5. repeat from 2. until done, else click "Nozzle Up"

"Down To Discard"

Well, this depends on your discard position and preference.

"NozzleOffset(X,Y)"

1. create a reference, ideally a thin lined cross (like a bullseye)
2. "System Config" -> "Nozzle" -> "Measure"
3. aim center of cross with down vision
4. click "Reference" "SetXY"
5. move nozzle 1 exactly to the center of the cross, lowering the nozzle onto the cross surface
6. click "Nozzle alignment reference point" "Nozzle1:" "SetXY"
7. move nozzle 2 exactly to the center of the cross, lowering the nozzle onto the cross surface
8. click "Nozzle alignment reference point" "Nozzle2:" "SetXY"
9. click "Save"

Prick calibration

1. choose vision mode
2. down vision aim part at pick position, click "Set XY" this uses always the same button:
3. click "Prick MoveTo"
4. click "Prick Comp" - this will move the tape one component
5. click "Nozzle MoveTo" - this will move nozzle 1 down to the component, nozzle should sit on center of component, if not:
   1. too far left: decrease "PrickOffset" X
   2. too far right: increase "PrickOffset" X
   3. prick does not land in tape hole, too far to the back: decrease "PrickOffset" Y
   4. prick does not land in tape hole, too far to the front: increase "PrickOffset" Y
6. repeat from 3. until nozzle lands in center of part
