Abstract
Delamination of a laminated multilayer stack is provided by generating a layer-specific energy distribution in the stack during delamination. A localized energy transferrer can generate localized heating, cooling heating, cooling, or other form of energy absorption or transmission, in a bonding layer of a multilayer stack. Localized energy transfer can include thermal energy transfer, such as heating and/or cooling, acoustic energy transfer, such as applying ultrasonic energy, electromagnetic energy transfer, such as applying laser light, directed microwaves, etc. Localized energy transfer can generate a layer-specific energy distribution that can weaken the bonding layer while reducing damage to other layers of the stack.
