Abstract
A board management system includes an extraction means and a generation means. The extraction means extracts a feature amount that depends on position deviation, for each of a plurality of specific components determined in advance based on a degree of variation in the component mounting position, among a plurality of components in a board image in which a board is captured. The generation means generates individual identification information to be used for identifying a board, from the extracted feature amount.
Claims7
A board management system comprising:
- a memory containing program instructions;
- and
- a processor coupled to the memory, wherein the processor is configured to execute the program instructions to:
- determine a plurality of specific components from a plurality of components on a board;
- extract a feature amount that depends on a position deviation for each of the plurality of specific components determined;
- and
- generate an individual identification information that uniquely identifies the board from the extracted feature amount,
- wherein the processor is configured to further execute the program instructions to:
- calculate a score representing a degree that a self-alignment effect is expectable for a plurality of components soldered to the board by reflow soldering, among of the plurality of components on the board, and
- determine the plurality of specific components based on the score.
A board management method comprising:
- determining a plurality of specific components from a plurality of components on a board;
- extracting a feature amount that depends on position deviation for each of the plurality of specific components determined;
- and
- generating an individual identification information that uniquely identifies the board from the extracted feature amount,
- wherein the determining the plurality of specific components comprises:
- calculating a score representing a degree that a self-alignment effect is expectable for a plurality of components soldered to the board by reflow soldering, among of the plurality of components on the board, and
- determining the plurality of specific components based on the score.
A non-transitory computer-readable storage medium storing thereon a program comprising instructions for causing a computer to execute processing to:
- determine a plurality of specific components from a plurality of components on a board;
- extract a feature amount that depends on a position deviation for each of the plurality of specific components determined;
- and
- generate an individual identification information that uniquely identifies the board from the extracted feature amount,
- wherein the determining the plurality of specific components comprises:
- calculating a score representing a degree that a self-alignment effect is expectable for a plurality of components soldered to the board by reflow soldering, among of the plurality of components on the board, and
- determining the plurality of specific components based on the score.
