Claims (14)

The electronic components mounted on the substrate a repair tool for blowing hot air,
A cylindrical main body having an opening for accommodating the electronic component formed on the bottom surface,
With the opening of the cylindrical body accommodating the electronic component in the opening, the hot air is allowed to flow downward from the inside of one side wall surface of the cylindrical body to the electronic component. A repair tool configured to be discharged to the outside from below the second side wall surface facing the one side wall surface through a space between the substrate and the substrate. In consideration of the size of the electronic component to be repaired, the opening of the cylindrical main body is arranged on the inner side of the lower end of the second side wall surface of the cylindrical main body and the inner side of both side walls adjacent to the second side wall surface. The repair tool according to claim 1, wherein the repair tool has a shape capable of contacting a side surface of the electronic component. Hot air inflow for preventing the hot air from flowing into the inner side of the second side wall surface of the cylindrical main body and the inner side surfaces of both side walls adjacent to the second side wall surface from the side of the side wall surface. 2. The repair tool according to claim 1, wherein a prevention means is provided. The hot air inflow prevention means includes a plate-like body having a shape surrounding at least a second side wall surface inside the cylindrical main body and both side wall inner surfaces adjacent to the second side wall surface, and a lower surface of the plate-like body The repair tool according to claim 3, wherein the electronic device is configured to be able to contact a peripheral edge portion of the upper surface of the electronic component. The plate-like body is configured to be movable in the vertical direction along the inner side of the second side wall surface of the cylindrical main body and the inner side surfaces of both side walls adjacent to the second side wall surface. Item 5. The repair tool according to Item 4. The repair tool according to any one of claims 1 to 5, further comprising discharge direction changing means for changing a discharge direction of hot air discharged from below the second side wall surface of the cylindrical main body. The electronic components mounted on the substrate a repair tool for blowing hot air,
An opening for accommodating the electronic component includes a cylindrical main body formed on the bottom surface,
With the opening of the cylindrical body accommodating the electronic component in the opening, the hot air is caused to flow downward from the inside of a plurality of side wall surfaces excluding one side wall surface of the cylindrical body to the lower side of the electronic component. The repair tool is configured to be discharged from the bottom of the one side wall surface through between the electronic component and the substrate. In consideration of the size of the electronic component to be repaired, the opening of the cylindrical main body has a shape capable of contacting the side surface of the electronic component only inside the lower end portion of one side wall surface of the cylindrical main body. The repair tool according to claim 7. The hot air inflow prevention means for preventing the hot air from flowing into the lower side of the electronic component from the one side wall surface side is provided inside the one side wall surface of the cylindrical main body. The repair tool described. The hot air inflow prevention means includes a plate-like body having a shape surrounding at least one inner side wall surface of the cylindrical main body, and is configured such that the upper peripheral edge of the electronic component can be brought into contact with the lower surface of the plate-like body The repair tool according to claim 9, wherein the repair tool is provided. The repair tool according to claim 10, wherein the plate-like body is configured to be movable in a vertical direction along an inner side surface of the cylindrical main body. The repair tool according to any one of claims 7 to 11, further comprising discharge direction changing means for changing a discharge direction of hot air discharged from one side wall surface of the cylindrical main body. The repair tool according to claim 1, wherein the cylindrical main body includes a heat insulating member. An apparatus for repairing an electronic component, to which the repair tool according to any one of claims 1 to 13 is mounted.
