Abstract (en)
[origin: CA3128288A1] The invention relates to a method for separating a first mechanical part (12) from a second mechanical part (14), wherein the second mechanical part (14) is bonded to the first mechanical part (12) by an adhesive film (16) along a connecting area, the first mechanical part (12) having a first specific thermal conductivity and the second mechanical part (14) having a second thermal conductivity that is higher than the first thermal conductivity, characterised in that it comprises at least one cooling step during which the second mechanical part (14) is cooled to a negative temperature and at least one stressing step during which the second mechanical part (14) is subjected to mechanical stress in order to cause the adhesive film (16) to break.
