Patent ID: 7963434

Claim:
A method of removing a micro component soldered to a substrate from the substrate, the method comprising: applying a thermosetting adhesive over a surface, on the opposite side to the substrate, of the micro component; abutting a tip of a component holding pin in a bar shape against the surface of the micro component via the thermosetting adhesive; fixing the component holding pin to the micro component in a way that hardens the thermosetting adhesive by spot-irradiating with a soft beam and heating the thermosetting adhesive; melting solder by spot-irradiating with the soft beam and heating the solder placed between the micro component and the substrate; embedding, after the solder has been melted, a solder leveling pin in a bar shape, which is disposed on both sides of the component holding pin alongside the component holding pin, into the solder exposed on both sides of the micro component; and removing the micro component from the substrate by moving the component holding pin in such a direction as to get distanced from the substrate, wherein the soft beam is irradiated alongside the component holding pin and the solder leveling pin.
