VisionCommandGroup

Bases: ModuleCommandGroupBase

This command group contains functions for working with SENTIO's vision module. You are not meant to instantiate this class directly. Access it via the vision attribute of the SentioProber class.

Attributes:

Name Type Description
camera VisionCameraCommandGroup

A subgroup to provide logic for camera specific functions.

imagpro VisionIMagProCommandGroup

A subgroup to provide logic for IMagPro specific functions.

compensation VisionCompensationGroup

A subgroup to provide logic for compensation specific functions.

align_die(threshold=0.05)

Perform a die alignment.

Die alignment compensates for positional differences when working with diced wafers which contain single dies.

Parameters:

Name Type Description Default
threshold float

The alignment threshold.

0.05

Returns:

Type Description
Tuple[float, float, float]

A tuple with the x, y and theta offset in micrometer.

align_wafer(mode)

Perform a wafer alignment.

Parameters:

Name Type Description Default
mode AutoAlignCmd

The alignment procedure to use.

required

Returns:

Type Description
Response

A Response object.

auto_focus(af_cmd=AutoFocusCmd.Focus)

Perform an auto focus operation.

Parameters:

Name Type Description Default
af_cmd AutoFocusCmd

The auto focus command to execute.

Focus

Returns:

Type Description
float

The focus height in micrometer

detect_probetips(camera, detector=DetectionAlgorithm.ProbeDetector, coords=DetectionCoordindates.Roi)

Executes a built in detector on a given camera and return a list of detection results.

Parameters:

Name Type Description Default
camera CameraMountPoint

The camera to use for detection.

required
detector DetectionAlgorithm

The detection algorithm to use.

ProbeDetector
coords DetectionCoordindates

The coordinates to use for the returned detection results.

Roi

Returns:

Type Description
list

A list of detected tips. Each detection result is a tuply of 6 values: x, y, width, height, score, class_id.

enable_follow_mode(stat)

Enable or disable the scope follow mode.

If scope follow mode is active the scope will move in sync with the chuck. This is useful for keeping the image in focus while moving the chuck.

This function wraps the "vis:enable_follow_mode" remote command.

Parameters:

Name Type Description Default
stat bool

A flag indicating whether to enable or disable the follow mode.

required

Returns:

Type Description
Response

A Response object.

find_home()

Find home position.

This function uses a pre-trained pattern to fully automatically find the home position.

Returns:

Type Description
Response

A Response object.

find_pattern(name, threshold=70, pattern_index=0, reference=FindPatternReference.CenterOfRoi)

Find a trained pattern in the camera image.

Parameters:

Name Type Description Default
name str

The name of the pattern to find.

required
threshold float

The detection threshold. The higher the threshold, the more certain the detection must be.

70
pattern_index int

The index of the pattern to find. In SENTIO each pattern may have up to 5 alternate patterns. This is the index of the alternate pattern.

0
reference FindPatternReference

The reference point to use for the pattern detection.

CenterOfRoi

has_camera(camera)

Check wether a given camera is present in the system.

This function wraps the "vis:has_camera" remote command.

Parameters:

Name Type Description Default
camera CameraMountPoint

The camera mount point to check.

required

Returns:

Type Description
bool

True if the camera is present, False otherwise.

match_tips(ptpa_type)

For internal use only! This function is subject to change without any prior warning. MPI will not maintain backwards compatibility or provide support.

remove_probetip_marker()

Remove probetip marker from the camera display.

Returns:

Type Description
Response

A Response object.

snap_image(file, what=SnapshotType.CameraRaw, where=SnapshotLocation.Prober)

Save a snapshot of the current camera image to a file.

Parameters:

Name Type Description Default
file str

The file name to save the image to.

required
what SnapshotType

The type of snapshot to take.

CameraRaw
where SnapshotLocation

The location where to store the snapshot. By default this is the prober control computer. If SnapshotLocation.Local is specified the image is download from the probe computer and stored loacally.

Prober

Returns:

Type Description
None

A Response object.

start_fast_track()

Start the fast track process as defined in SENTIO.

FastTrack is a feature that combines multiple preparation steps into one command. You need to have set up FastTrack in the VisionModule/Automation/FastTrack side panel editor to use this command.

Returns:

Type Description
Response

A Response object.

switch_all_lights(stat)

Switch all camera lights on or off.

This function wraps the "vis:switch_all_lights" remote command.

Parameters:

Name Type Description Default
stat bool

A flag indicating whether to switch the lights on or off.

required

Returns:

Type Description
Response

A Response object.

switch_camera(camera)

Switch the camera to use for the vision module.

Parameters:

Name Type Description Default
camera CameraMountPoint

The camera to switch to.

required

Returns:

Type Description
Response

A Response object.

switch_light(camera, stat)

Switch the light of a given camera on or off.

Parameters:

Name Type Description Default
camera CameraMountPoint

The camera to switch the light for.

required
stat bool

A flag indicating whether to switch the light on or off.

required

Returns:

Type Description
Response

A Response object.
