What This Means for Your Design
Imagine you have a stack of delicate, super-thin pancakes that need to be cut into specific shapes. Instead of using a knife that might crush them, this method 'lifts' the top layers off a special base, leaving the shapes you want without damaging them. This is great for making tiny electronic parts from special materials.
