Creating the PCB data

specifying an alternative component, see “8. Alternative components” in

Chapter 6.

13. Use feeder opt.

Set to “Yes” when you want to change the feeder set positions according to

results obtained with the DATA GENERATOR commands. (See “9. Data

optimization” in this chapter.) Set to “No” if you do not want to change

these positions. Setting to “Yes” is advised.

14. Comp. Group No.

When a nozzle lowers to mount a low-profile component after tall

components have been mounted on the PCB, the neighboring nozzles may

interfere with those tall components. To avoid this, components can be

grouped by height so that they are mounted in the desired order (0 to 99).

When no mounting order is needed, set this parameter to “0”.

15. Correct Pickpos.

Set this parameter to “NotUse” in normal operation.

3. PICK & MOUNT INFO. parameters

21. Pick Angle deg

This parameter specifies the angle through which the mounter head rotates

to pick up a component on the feeder. This setting determines the orienta-

tion of the component (recognition reference) when it is recognized and

displayed on the vision monitor. Normally, set this parameter to 0° for

horizontally long components in the loading position on the feeder, and set

to 90° for vertically long components. When you are using a bulk cassette

feeder, always set this parameter to 90°.

Pickup angle

CAUTION

Pickup angle setting directly affects the recognition reference and mounting angle. Be

careful not to mistake 0° for 180° for horizontally long components in the loading

position and 90° for -90° for vertically long components.

22. Pick Timer, Mount Timer

These parameters specify the time duration (in seconds) for which the head

stays in the lowered position after detecting the reference pickup or mount

vacuum pressure when picking up or mounting a component. For small

Chapter 5

components such as chip components, it is okay to set these parameters to

“0.00”.

23. Pick Height, Mount Height

These are the Z-axis height offset values used when the head lowers to

pick up or mount a component. Set these parameters to “0” in normal

operation.

If you want to lower the Z-axis height during component pickup or

mounting, enter a plus value in the Pick Height or Mount Height column.

Conversely, if you want to raise the Z-axis height, enter a minus value.

24. Pick Sequence

This parameter specifies the timing to start vacuum generation when the

head picks up a component. When set to “Normal”, vacuum generation

starts before the head moves down. When set to “Bottom”, vacuum

generation start after the head has moved down. Set this parameter to

“Normal” in most cases.

25. Mount Action

This specifies the nozzle descent movements during component mounting.

Set this parameter to “Normal” in most cases.

26. Vacuum Check

Set this parameter to “NORMAL CHK” in normal operation. If you want

to check pickup errors and mount errors strictly (head return without

mounting the component), set to “SPECIAL CHK”.

NOTE

When the Vacuum Check parameter is set to “NORMAL CHK”, the machine controls the

ascent timing of the head from the lowered position during component pickup or mount-

ing. This parameter setting is valid only when the Vacuum Check parameter on the PCB

Info. screen is set to “Check”.

27. Pick Vacuum, Mount Vacuum

These are reference vacuum pressures used for checking the pickup and

mount vacuum levels. Use the default settings and adjust them as needed

in the Adjust Assistant mode. (See “3.7” in this chapter.)

28. Conv. Y Speed

This parameter specifies the conveyor Y-axis moving speed. Set to “FAST”

as long as no problem occurs. But, if the mounted components move or

slide on the PCB due to the Y-axis movement, set this parameter to a

slower speed.

4. DUMP INFO. parameters

31. Dump Way

This specifies the location where a component will be dumped if an error

such as recognition error has occurred. Set to “Dump POS”. (See the

Discard point parameter explained in the mounter service manual.)

32. Retry Times

This determines how many times the machine will retry the same operation

if an error such as a recognition error has occurred. The number of retries

can be set from “NO RETRY” to “14”. When this retry setting is greater

than the machine data retry setting (Retry Limit parameter explained in the

mounter service manual), the machine data has priority.

5. VISION INFO. parameters

41. Alignment Group

Set this parameter to “Chip”.

42. Alignment Type

Set this parameter to “Std.Chip”.

43. AlignmentModule

This parameter specifies the lighting method for recognizing a component.

Use the default setting (Fore&Back&Laser) in most cases. Since the

YV180X surface mounters do not use “Back” (back light unit) and “Laser”

(laser unit), “Fore” (reflective lighting) is automatically selected.

44. Light Selection

Set this parameter to “Main + Coax” in most cases.

45. Lighting Level

This parameter specifies the reflected light brightness. Normally, use the

default setting and then optimize it in the Adjust Assistant mode (see

“3.7”).

46. Comp. Threshold

This parameter specifies the threshold level used to discern the light-

reflecting part (lead) from the background during component recognition.

Normally, use the default setting and then optimize it in the Adjust

Assistant mode (see “3.7”).

47. Comp. Tolerance

This specifies the tolerance for recognizing a component, in an allowable

error percentage of 0 to 100%. The larger the percentage, the greater the

tolerance. First use the default setting and then gradually increase it while

checking the recognition status monitored with the VISION TEST

command in the Adjust Assistant mode (see “3.7”).

48. Search Area

This parameter specifies the area within which the component leads are

searched. As this value is set larger, the search area is extended, but with a

loss in the image processing speed. First use the default setting and then

optimize it in the Adjust Assistant mode (see “3.7”).

49. Datum Angle

This parameter specifies the angle of component shape definition. Use the

default setting in most cases. (This parameter is displayed only when the

Option Edit parameter on the <3/1/A1 OPTION CONFIG.> screen is set to
