Process - Vision

Vision Type

Refer to section Åu4.6Vision Type DetailsÅv for details on settings for this item.

Multi Camera

Specify the possible camera type(s) for the part. When no camera for the NXT is specified,

then any camera that can be used for the specified part data settings is used. If a camera(s)

is specified, then only that camera(s) can be used.

Vision Height Offset

This option is enabled when the side light camera is used in image acquisition. The use of

this option allows the image to be acquired with light hitting pin tip positions rather than the

bottom surface of the part.

Vision Area Offset X

This option is enabled for odd-form parts (when "240" to "243" is set in Vision Type and

image acquisition is performed). If the lead(s) of an odd-form part is protruding beyond the

image acquisition range, the range within which the image is acquired can be moved.

Vision Area Offset Y

This option is enabled for odd-form parts (when "240" to "243" is set in Vision Type and

image acquisition is performed). If the lead(s) of an odd-form part is protruding beyond the

image acquisition range, the range within which the image is acquired can be moved.

Exposure Time (VPDplus)

Displays the exposure time (msec) that is specified in VPDplus. If "0" is displayed, then the

exposure time is automatic based on the vision type. This setting can only be changed in

VPDplus.

Lighting Pattern (VPDplus)

Displays the lighting pattern that is specified in VPDplus. If "0" is displayed, then the lighting

pattern time is automatic based on the vision type for NXT and AIM machines. This setting

can only be changed in VPDplus. This setting is not used for machines other than NXT and

AIM.

Process - Pin Check

Pin Check Mode

Specify the type of check to be performed to check the direction of the part. The checks

“Bottom Mark” and “Bump” are supported on the NXT. If a mode other than those two are

specified, then the NXT ignores the pin check modes settings and a direction check is not

performed. If the part matches the specified conditions, then the part direction is

considered to be correct and normal vision processing is performed. If the part does not

match the specified conditions, then the direction is considered to be incorrect and an error

occurs.

Is Bottom Mark Present

This setting only displays if “Bottom Mark” is specified for the pin check. Specify whether

or not a bottom mark should be present in the specified area for orientation to be judged as

being correct.

Is Bump Present

This setting only displays if “Bump” is specified for the pin check. Specify whether or not a

bump should be present in the specified area for orientation to be judged as being correct.

Upper Left X

Specify the upper left X-coordinate of the check range in millimeters. The reference point

is the center of the body with the part oriented in the zero direction.

Upper Left Y

Specify the upper left Y-coordinate of the check range in millimeters. The reference point

is the center of the body with the part oriented in the zero direction.

Lower Right X

Specify the lower right X-coordinate of the check range in millimeters. The reference point

is the center of the body with the part oriented in the zero direction.

Lower Right Y

Specify the lower right Y-coordinate of the check range in millimeters. The reference point

is the center of the body with the part oriented in the zero direction.

Setting Description

Bottom

Mark

This is used to check for the presence or absence of

a mark on the bottom of a part in a specified location.

This check can be performed for all vision types.

Bump This is used to check for the presence or absence of

a bump (ball lead) on the bottom of a part in a

specified location. This check can only be

performed for vision types that are for parts with

bumps.

NXT Programming Manual 97

Process - Coplanarity

Do Coplanarity

Specify whether a coplanarity check is made with the optional coplanarity unit. Refer to the

coplanarity manual for information on the settings in this section.

Coplanarity Editor

Click to start the Coplanarity Editor for making coplanarity data for the optional coplanarity

unit. Refer to the coplanarity manual for more information.

Process - Flux

Do Flux

Specify whether or not flux is to be applied.

Dwell Time

Specify the length of time (sec) for the Z-axis to stay at the bottom of its travel to keep a part

dipped in flux.

Slow Dipping Height

Specify the height at which the Z-axis starts decelerating on its descent to the flux and ends

accelerating on its ascent from the flux.

Slow Dipping Down Speed

Specify the speed (%) after deceleration of the Z-axis during flux application. However, if

the machine has a [Slow Dipping Speed] setting specified, then that setting is used.

Slow Dipping Up Speed

Specify the speed (%) before acceleration of the Z-axis rising during flux application.

However, if the machine has a [Slow Dipping Speed] setting specified, then that setting is

used.

Squeegee Height

The film thickness during flux application for each part can be changed by specifying the

squeegee height. Set the squeegee height to the required film thickness amount.

Do Dipping Check

Specify whether or not to inspect for dropped parts when dipping parts in flux.

Process - Solder Paste

Do Check

Specify whether to check the application status of the solder paste. (Currently, only bump
