METHOD FOR MANUFACTURING PLASTIC METALIZATION THREE-DIMENSIONAL WIRING

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing plastic metalization three-dimensional wiring as a method for manufacturing three-dimensional metalization layout wiring to be formed on a three-dimensional plastic body.

SOLUTION: The method for manufacturing plastic metalization three-dimensional wiring includes the steps of: subjecting a plastic body having a 3D structure to a surface pretreatment; then subjecting the resulting body to a metalization treatment for deposition to form a metal thin film layer; then subjecting the resulting body to a photoresist application treatment to form a photoresist protective layer; then subjecting the resulting body to an exposure/lithography treatment to form a patterned photoresist protective layer; then subjecting the exposed metal thin film layer to an etching treatment to form a patterned metal wiring layer; then subjecting the patterned photoresist protective layer to a peeling treatment; and then subjecting the patterned metal wiring layer to a surface layer treatment to form a metal protective layer. In this manner, the method can directly form a circuit pattern having a three-dimensional layout on the plastic body having the 3D structure, and can eliminate the need for separately installing a circuit carrier inside the plastic body, thereby responding to needs of weight saving and compactification.
