## Abstract

An information management device for managing information in a mounting system that mounts a component after determining usability of the component when the component is picked up from a wafer divided into multiple components and is mounted on a base material, includes an information storage section that stores various types of information, an information acquisition section that acquires information on a pickup position of the component on the wafer and information on a determination result of usability of the component, and an information processing section that stores information obtained by associating the pickup position of the component with the determination result of the usability in the information storage section.

## Claims

### Claim 1

An information management device for managing information in a mounting system that mounts a component after determining usability of the component, when the component is picked up from a wafer divided into multiple components and is mounted on a base material, the information management device comprising:
an information storage section configured to store various types of information;
an information acquisition section configured to acquire information on a pickup position of the component on the wafer and information on a determination result of usability of the component; and
an information processing section configured to store information obtained by associating the pickup position of the component with the determination result of the usability in the information storage section, wherein
the information processing section generates statistical information on an unusable rate in which the determination result of the usability is unusable for each pickup position of the component, and stores the statistical information in the information storage section,
the information management device further comprises an information output section configured to select a pickup position with a high unusable rate as a specified pickup position, based on the statistical information on the unusable rate, and thereafter output skip information for instructing to skip pickup of the component at the specified pickup position to a mounter included in the mounting system,
the information acquisition section acquires information on a mounting position of the component on the base material,
the information processing section stores information obtained by associating the pickup position of the component with the mounting position of the component in the information storage section, and
the information output section outputs information on a mounting destination of the component picked up from a neighborhood pickup position based on the information obtained by associating the pickup position of the component with the mounting position of the component as countermeasure information for the component at the neighborhood pickup position within a predetermined neighborhood range of the specified pickup position.

### Claim 2 (depends on 1)

The information management device according to claim 1, wherein the information output section outputs the skip information instructing to skip the pickup of the component at the neighborhood pickup position to the mounter as the countermeasure information.

### Claim 3 (depends on 2)

The information management device according to claim 2,
wherein the information acquisition section acquires information on a result of inspection of the component performed on the base material on which the component is mounted,
wherein the information processing section stores information obtained by associating the pickup position of the component, the determination result of the usability, the mounting position of the component, and the result of inspection with each other in the information storage section, and
wherein the information output section determines whether there is a correlation between a result determined to be bad in the inspection of the component picked up from the neighborhood pickup position and the specified pickup position, and outputs the countermeasure information when it is determined that there is the correlation.

### Claim 4

An information management device for managing information in a mounting system that mounts a component after determining usability of the component, when the component is picked up from a wafer divided into multiple components and is mounted on a base material, the information management device comprising:
an information storage section configured to store various types of information;
an information acquisition section configured to acquire information on a pickup position of the component on the wafer and information on a determination result of usability of the component; and
an information processing section configured to store information obtained by associating the pickup position of the component with the determination result of the usability in the information storage section, wherein
the information processing section generates statistical information on an unusable rate in which the determination result of the usability is unusable for each pickup position of the component, and stores the statistical information in the information storage section,
the information management device further comprises an information output section configured to select a pickup position with a high unusable rate as a specified pickup position, based on the statistical information on the unusable rate, and thereafter output skip information for instructing to skip pickup of the component at the specified pickup position to a mounter included in the mounting system,
the information output section outputs the skip information instructing to skip the pickup of the component at a neighborhood pickup position to the mounter as countermeasure information for the component at the neighborhood pickup position within a predetermined neighborhood range of the specified pickup position,
the information acquisition section acquires information on a mounting position of the component on the base material and information on a result of inspection of the component performed on the base material on which the component is mounted,
the information processing section stores information obtained by associating the pickup position of the component, the determination result of the usability, the mounting position of the component, and the result of inspection with each other in the information storage section, and
the information output section determines whether there is a correlation between a result determined to be bad in the inspection of the component picked up from the neighborhood pickup position and the specified pickup position, and outputs the countermeasure information when it is determined that there is the correlation.

### Claim 5 (depends on 4)

The information management device according to claim 4, wherein
the information processing section stores information obtained by associating the pickup position of the component with the mounting position of the component in the information storage section, and
the information output section outputs information on a mounting destination of the component picked up from the neighborhood pickup position based on the information obtained by associating the pickup position of the component with the mounting position of the component as the countermeasure information.

### Claim 6 (depends on 5)

The information management device according to claim 5, wherein the processor is further programmed to:
acquire information on a result of inspection of the component performed on the base material on which the component is mounted,
determine whether there is a correlation between a result determined to be bad in the inspection of the component picked up from the neighborhood pickup position and the specified pickup position, and
output the countermeasure information when it is determined that there is the correlation.

### Claim 7 (depends on 4)

The information management device according to claim 4, wherein the processor is further programmed to output the skip information instructing to skip the pickup of the component at the neighborhood pickup position to the mounter as the countermeasure information.
