Component

Specify where to discard a component.

- Trash box: available for all types of components.

- Tray restore: available for components whose packing style is a tray.

- Trash conveyor: available for components which can be centered with the VCS.

- Protect: available for all types of components.

If you set “Mecha” in the “Shuttle” cell of the “MTC/MTS/DTS” column on the

Expansion page when an MTC is used, do not set “Tray restore” here.

⑥

Trial

Use the radio whether or not the component is actually placed for trial.

⑦

Release check

This item is available only for a laser centering component, and functions to

check to see with laser if a component remains in the nozzle after the machine

places it on a board. With the corresponding radio button, specify whether to

check to see if a component is released.

Auto correct Pick

⑧

This item is for a laser centering tape component, and functions to correct a

pick-up position error based on the result of the laser recognition operation.

With the corresponding radio button, specify whether to correct a pick-up

position.

⑨

MTC Auto Teaching

When you set this item to “Yes”, the system automatically measures the center of

a component at each regulated point and the spot light indicates the center of a

component. During PWB production, the system automatically performs this

operation when production starts and when a tray is pulled for the first time after

the number of components is changed.

⑩

Component Skip

When you set this item to “Yes”, the specified type of components is skipped and

is not placed on a board. A placement data record specifying a skipped

component is not used for placing components on a board during production, but

is not added to the “Unplaced list”.

− When component information is loaded from the database, data specifying a

skipped component is not loaded to the system.

⑪

MTS Mark Recog. (Recognition)

If you set the “Pick reference position mark” to “Yes” when an MTS is used, the

system recognizes a component pick-up reference position mark when a tray on

which the specified component is located is pulled out, and corrects the actual

coordinates for picking up or returning a component.

⑫

Component layer

When the same layer is specified as that in Placement data, set the priority

unique to each component.

Set the layers from 0 to 7 on the pop-up menu shown below.

− Nozzle data

Only when you can enter the nozzle number for specifying a nozzle in the

“Centering” field (that is, the corresponding check box is checked), you can enter

this menu item.

The associated initial values of the nozzle data are set every time you enter the

nozzle number.

①

Grip Position

Enter the offset from the center of a component to the center of the

pushed-up surface of the arm located on the gripper nozzle fixed side into

the “Y” field together with a minus sign. Do not enter any figure except “0”

into the “X” field.

②

Horizontal Clearance

Enter the clearance between the pushed-up surface of the arm located on

the gripper nozzle and a component together with a minus sign.

③

Nozzle Direction at Picking

Specify the nozzle direction to be set when it picks up a component that is

supplied at 0 degrees. Enter a figure among 0, 90, 180 and 270.

④

Height Adjustment

Enter a value for correcting the component pick-up height (used together

with the push-up stroke).

4.7.6 Tack control section (Expansion page)

Since the default values are always set at the items on the Expansion page, normally

you do not have to change them. Only if you want to change the default setting,

open this Expansion window. Note that some items may be reset to their default

values if you change items on the Basic, Centering or Component packaging window

after you change the setting of items on the Expansion page.

(1) Laser centering

①

Set in the combo box the accelerations of the X and Y axes to move the

component to the placement position after it is picked.

②

Pick Z down

You can select any of the same choices as those displayed in the "XY"

combo box.

This selection is useful to adjust the vertical stress imposed on a component

or adjust shock given to a board.
