Abstract:
1. A removing method for an electronic component that removes from a substrate an electronic component soldered to the substrate with the use of solder bumps, the removing method comprising: moving a tool for receiving the electronic component to the electronic component on the substrate to detect contact of the tool, with the electronic component on the substrate; raising a heating temperature of the tool, electronic component and the substrate up to a maximum heating temperature starting from the contact of the tool as well as moving the tool in response to the temperature rising; moving the tool to a stopped position where the maximum heating temperature is achieved, such that the electronic component maintains contact with the substrate; moving the electronic component from the stopped position where the maximum heating temperature is achieved to a mounting height of the substrate through movement of the tool so that the tool receives the electronic component from the substrate; and preheating the tool and the substrate before the tool contacts the electronic component, wherein the maximum heating temperature corresponds to thermal deformation of the substrate.
