|
A) Operation mode Choose a one-way print operation (Single) or a to-and-fro print operation (Double). |
B) Priority after printing Set which should move first after printing; lift, squeegees or both together. |
Lift : The squeegees are fixed and the mask is snapped off while the squeegees are |
down. After that, the squeegees rise up. |

Squeegee : After the squeegees have been raised, the mask is snapped off. |
Together : Raising the squeegees and snap-off start simultaneously. When this mode is |
Supports : set, the snap-off speed switching is fixed to the uniform velocity mode. A mask is clamped with a lift positioned at the print height, and only supports are |
used in snap-off. At this time, a board needs to be vacuumed by the vacuum |
pump. |

H) Printing pressure teaching data selection Pressing this switch displays the <Press. teach data list> screen. |

When squeegees are changed, the actual printing pressure becomes different from the set value |
owing to the change in the weight of the materials. Therefore, be sure to perform the printing |
pressure teaching before production. |

2. Printing range Input the print-operation range for squeegees. If nothing has been input, the board is printed from end to end. When the printing area is limited to a portion of the board, inputting this value adjusts the range and can improve the tact time. When .30 is input |

A) Clearance It is used to adjust the clearance between mask and board. When “0” is input, there will be no clearance. When performing the minus-contact printing that our company recommends, input the value “.0.5.” |
B) Lowering speed It is used to adjust the snap-off speed required for stable snap-off. |
C) Lowering stroke It is used to adjust the snap-off distance required for stable snap-off. |
D) Snap-off speed switching Choose the lowering speed from among the following five modes. High-speed multiple snap-off is a sophisticated snap-off operation evolved from an accelerative snap-off so that the snap-off performance will be improved drawing on various kinds of solder characteristics. A favorable snap-off performance can be obtained and a cycle time can be reduced. |
Uniform velocity : The support blocks lower the lowering-stroke distance at a uniform |
velocity. |
|
|
|
Acceleration : The speed of support blocks accelerates slowly, and eventually it |
reaches the lowering speed. |
|
Acceleration High : An accelerative snap-off is carried out at higher speed. |
High-speed multiple : The speed of support blocks accelerates to the one that is faster than |
Email:smt@smtsky.com,Website:www.smtsky.com |
Email:smt@smtsky.com,Website:www.smtsky.com |
(Recommended) the lowering speed, and eventually it reaches the lowering speed. |
Multiple : The speed of support blocks accelerates slowly, and eventually it |
reaches the lowering speed. |
|
(If the snap-off performance is still bad even in the acceleration mode, |
choose the multiple mode. In this mode, however, the cycle time |
becomes longer than the one in the acceleration mode.) |
. If the snap-off performance is bad due to such as a narrow pitch, choose the acceleration mode. In this mode, however, a cycle time becomes longer compared with the other snap-off. |

4. Speed changing mode This is used when solder-filling amount needs to be controlled during printing, such as in the through hole printing or in the fine-pitch printing. Pressing [Speed change] highlights it in blue, and then [Set], which is located in the right of that, becomes available (indicated in black). Pressing [Set] switches to the <Printing speed change mode> screen. |

2 ‘Position’ Set the range of each zone. Regard the front end face of board as 0 mm. For each zone, you can choose from 0 mm up to board width; however, if zones are interfered with each other, a data check error occurs. If the zone positions are set as follows, a data check error occurs. cOne zone is including another. dOne zone is overlapping another. Zone 2 Zone 2 Zone 1 . Overlapped range Zone 1 If the printing-range offset in the print conditions data has been set, note that the setting range becomes narrow according to the setting of the printing-range offset value. |
3 ‘Speed’ Set the print speed in the range of each zone. The setting range of speed is 5.0 mm/s to 400.0 mm/s. For the outside of zone, note that printing is carried out at the print speed set in the print conditions data. |
4 ‘Prd data PCB W’ This displays the board width that is set in the board data in data modification menu. The data cannot be modified. |
5 ‘A speed except for the zone.’ This displays the print speed (F→R, R→F) that is set in the print conditions data. The data cannot be modified. |

Dry cleaning: Removes solder balls and flux (from the apertures and the back of mask). Wet cleaning: Removes the thin-film-like flux residues (from the back of mask). |
NOTICE When using the wet cleaning, you are recommended to set it for the “Forward” motion of the second cleaning in two-round cleaning mode. If the wet cleaning is used in one-round cleaning mode, the cleaning performance may be insufficient depending on the type of solder. |

|
1. About the library data |
|
|
The data that are difficult to adjust (e.g., print conditions data, cleaning data, or print counter) can be saved as a library. Even the operators who are unaccustomed to the machine can easily create the data by loading the prepared data as a set. The library, by default, has 69 patterns by solder type and 4 patterns by print accuracy. In addition, it is possible to add user-created library data. |
