Title: METHOD FOR SEPARATING MEMBER USING LASER LIGHT
Abstract:
A method for separating a first member (10) and a second member (20) which are stuck together with an adhesive tape (30) from one another, wherein a laser light non-transmissive part of at least one of the first member (10), the second member (20) and the adhesive tape (30) is irradiated and heated with a laser light (L), causing an adhesive layer of the adhesive tape (30) to be in at least one of a softened, melted, foamed or decomposed state with this heat in order to reduce the adhesive strength of the adhesive layer.
