METHOD OF REWORKING PRINTED CIRCUIT BOARD, AND REWORK JIG FOR PRINTED CIRCUIT BOARD

摘要

PROBLEM TO BE SOLVED: To provide a method of reworking a print circuit board which requires short heat-up time for removing/attaching chip components, decreases a thermal influence on peripheral components due to heating, and facilitates the removal of a remaining solder.;SOLUTION: When a chip component mounted on a printed circuit board is heated to melt a solder to be removed from the substrate and a new component is attached, a rework jig equipped with a tweezer portion having a pair of claw tips clipping and holding a component and made from ceramic, and a heating portion at a place adjacent to the tweezer portion is used. A method of reworking a print circuited board includes: a step of clipping the chip component with the tip claws of the tweezer portion and removing the component after soldering and melting the component by heat transfer from the heating portion; a step of removing and ground leveling a remaining solder on the component with the claw tips of the tweezer portion; a step of clipping the new component with the claw tips of the tweezer portion and adhering a solder to the component; and a step of mounting the component on the substrate and heating the solder by the heat transfer from the heating portion to be attached with the chip component.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2018,JPO&INPIT
