TRACING DEVICE
A tracing device includes an appropriateness determination section configured to determine whether an image processing, which is executed in a production process of a board product by a board work machine, satisfies an appropriateness condition indicating reliability of a result of the image processing when the result of the image processing stays within a permissible range in which the result of the image processing is determined normal and an information management section configured to record image data used in the image processing as traceability information according to the result of the determination made by the appropriateness condition determination section.
Component mounting device
A component mounting device includes a heater unit which heats along a range which is narrower than a movement range of a head and which is a partial length of a board, in which the head is controlled to mount components onto the board using a heating range of the heater as a mounting range, the board is conveyed to shift the mounting range every time mounting of components in the mounting range is completed such that an unmounted range in which components are not mounted on the board becomes the mounting range, and components are mounted in a new mounting range.
Production line safety system
In a component-mounted-board production line in which an automatic exchanging device moves along a row of multiple component mounters, each component mounter is provided with a power supplying section that supplies power wirelessly. The automatic exchanging device is provided with a power receiving section that receives electric power supplied wirelessly from the power supplying section of the component mounter that the automatic exchanging device is facing, a monitoring section that monitors whether a person or object has entered a monitoring area around the automatic exchanging device, and a safety circuit section that turns off the power supply to a motor that is the driving source of the automatic exchanging device but continues supplying power to the monitoring section and the like when the monitoring section detects that a person or object has entered the monitoring area.
Component mounting machine
There is provided a component mounting machine in which when detecting a lowermost end position of a component sucked by a suction nozzle, a lower edge position of the component is detected at predetermined intervals from a left side and a right side using the lowermost end position as a reference. The component mounting machine derives an approximate straight line obtained by approximating multiple lower edge positions detected from the side having a larger detection number and the lowermost end position and an angle of the approximate straight line is detected as the suction angle of the component. Accordingly, the component mounting machine can appropriately detect the suction angle of the component with a simple process and correctly determine the suction posture of the component.

TEMPERATURE MONITORING FOR PRINTED CIRCUIT BOARD ASSEMBLIES DURING MASS SOLDERING
A computer determines one or more temperature sensitive components from a part details in a bill of materials for soldering on a printed circuit board assembly, where the bill of materials is a record comprising part details having a reference designator. The computer determines whether temperature sensitive components exist in the bill of materials. Based on determining that at least one of the temperature sensitive components exist in the bill of materials, the computer determines temperature limits for each temperature sensitive component based on the reference designator, monitors, using the thermographic cameras the measured temperatures of the temperature sensitive components during soldering in the reflow oven. Then, based on determining that the measured temperatures of the temperature sensitive components exceeds the temperature limits, the computer determines an elapsed time outside of the temperature limit when the measured temperatures of the temperature sensitive components exceeds the temperature limits.
IN-SITU WARPAGE MONITORING DURING SOLDER REFLOW FOR HEAD-IN-PILLOW DEFECT ESCAPE PREVENTION
Embodiments of the present invention are directed to an in-situ warpage monitoring system and method for preventing head-in-pillow (HIP) or other potential defect escapes during a solder reflow process.
