(3) Operation of a coplanarity check

Create data of a production program from “Component data” to “Vision data,” and then select the

[Meas/Insp] command from the menu, and the [Coplanarity inspection] command on the displayed

menu.

The screen like one shown below appears.

1) Component being inspected

Component data necessary for a coplanarity check is displayed here.

2) Pick position (Pick-up position of a component to be measured)

Data on a position from which a component is picked up is displayed here. You can

change this pick-up position to the pick-up position of the previous alternate component or

that of the next alternate component also. If there is not any Pick data or if an MTC is

specified, each item is dimmed on the screen, so you cannot change the component pick-up

position, knock the feeder, or perform teaching operation.

● Update pick data with new coordinates

Specify whether to update Pick data with the taught result.

When you do not place a checkmark in this check box, the coordinates are applied to the

pick-up operation this time only.

● Feed

This button knocks a feeder to feed components.

3) Head (to be used)

You can select a head to be used for inspection. Select the desired head from the list of the

combo box.

4) Get parameters

When you press the <Adjustment of check conditions> button, the system obtains the

following data that allows the coplanarity inspection: “Exposure time,” “Inspection angle”

and “Alternative angle,” which means the alternative inspection angle.

5) Result of inspect

The image recognition result or the coplanarity check result is displayed here.

● Status

If the machine measures an object successfully, “OK” is displayed here. Otherwise,

“NG” is displayed.

● Comment

The cause of an error is displayed here.

● <Vision recog. information> button

If the image check result is “NG,” this button allows you to display the detailed

information on the error on the screen.

The machine can display the detailed data on the 16th error from the latest one.

The detailed information on image recognition errors is displayed on the screen from the

latest one.

<Previous page> : Displays information on the previous image recognition error.

<Next page> : Displays the next information on the current image recognition error.

<Help> : Displays the Help function appropriate for the image recognition error

displayed currently.

<Exit> : Closes the image recognition error information screen.

Each item of the detailed image recognition error information is described in the table below.

Displayed item

Description

Total part recog.

count

Number of times the machine recognized a component

Page

Page number of the displayed image recognition information

Head information

Head number

Name

Component name specified in Component data

No.

Number specified in Component data

Error Code

Actual image recognition error code

Result

Unprocessed character string of the result

Recognition result (Offset for the center of the screen in the X direction)

The right direction of the VCS monitor is positive.

Recognition result (Offset for the center of the screen in the Y direction)

The upper direction of the VCS monitor is positive.

Angle

Recognition result (Offset for the center of the screen in the θ direction)

The anticlockwise direction of the VCS monitor is positive.

Side

Side at which an error was detected (Up/down/left/right)

This is not the side displayed on the monitor but the side of the Top-View specified in Vision

data.

Lead No.

Number of a lead at which an error was detected (from 1).

Lead number specified anticlockwise in the Top-View specified for a missing lead

If two or more error occurs, the number of a lead at which the machine detected an error for

the first time is displayed here. For a general-purpose vision component, the lead (ball)

number counted from the first element is displayed here.

Level

If a lead bending error occurs, the lead bending ratio to the lead pitch (%) is displayed here.

If a ball is deformed or if a ball diameter error occurs, the deformation ratio to the ball

diameter (%) is displayed here. (in increments of 0.1 %)

Lead Num.

Total number of leads detected actually

BGA row

Row number of a ball of an area array component at which an error was detected

This is a line number displayed on the VCS monitor not related to the Vision data. (That is,

a line number sequentially assigned from 0 and counted from the top of the VCS monitor to

the bottom.) If two or more error occurs, the row number of a ball at which an error is

detected first is displayed here.

BGA column

Column number of a ball of an area array component at which an error was detected

This is a column number displayed on the VCS monitor not related to the Vision data.

(That is, a column number sequentially assigned from 0 and counted from the left of the

VCS monitor to the right.) If two or more error occurs, the column number of a ball at

which an error is detected first is displayed here.

Lead pitch

Actual lead (ball) pitch of a component that caused a lead (ball) pitch error

This is output only for a component whose actual lead (ball) pitch is detected with the

machine. (in increments of 0.1 μm)

Ext. recog. details

error

5-digit character string indicating error information of an outline recognized component

“XX” of “XXYYY” indicates where the error occurred, and “YYY” indicates the cause of the

error.

Main error

Main error code of a general-purpose vision component (including some BGA components)

Sub error

Sub error code of a general-purpose vision component (including some BGA components)

This sub code indicates a specific internal event.

Detail error

Detailed error code of a general-purpose vision component (including some BGA

components)

The electrode

Number of leads of an extended-lead connector component specified in Vision data

Detect.

Total number of leads of an extended-lead connector component that were able to be

detected actually

Ball diameter

Actual diameter of a ball whose diameter and deformation were detected (in increments

of 0.1 μm)

Element

Number of an element group of a general-purpose vision component at which an error

occurred

Divide horizontal

If the division recognition pitch (in the horizontal direction) specified in a production

program is different from the actual movement distance, this difference is output here.

Divide vertical

If the division recognition pitch (in the vertical direction) specified in a production program

is different from the actual movement distance, this difference is output here.
