[0002] A flexible die-cut aluminum foil heating circuit board is an electronic component that combines the characteristics of a flexible circuit board and aluminum foil. This kind of circuit board is mainly used in occasions that need to adapt to complex shapes and spaces. Especially in the fields of mobile devices, medical devices, and aerospace, its bendable, foldable, and twistable characteristics make the design more flexible and innovative.
