Abstract

The invention relates to a method for manufacturing a three-dimensional circuit. The method comprises the following steps of: providing a body with a three-dimensional structure; carrying out surface degreasing and roughening treatments on the body; carrying out metallization treatment on the body surface, and forming a metal film layer through precipitation; carrying out photoresist coating treatment on the surface of the metal film layer so as to form a photoresist protective layer; carrying out exposure / developing treatment on the photoresist protective layer so as to form a patterned photoresist protective layer; etching the exposed metal film layer so as to form a patterned line layer; removing the photoresist protective layer from the patterned line layer; and carrying out chemical plating treatment on the surface of the patterned line layer so as to form a line thickening layer. According to the method disclosed by the invention, a three-dimensionally wired circuit pattern can be directly formed on the body with the three-dimensional structure, and a circuit carrier is unnecessary to arrange on the body additionally, therefore the requirements of lightness, thinness, shortness and smallness are met.

Description

technical field [0001] The invention relates to a method for manufacturing a three-dimensional circuit, in particular to a method for forming a three-dimensional patterned metal circuit on the surface of a body of a three-dimensional structure. Background technique [0002] With the rapid development of today's wireless communication technology, related electronic communication products pay more and more attention to the quality of signal transmission and meet the needs of light, thin, short and small. However, various mobile image communication products (such as tablet computers, mobile phones, etc.) need to design different antenna body structures and circuit forms according to different product appearances and internal structure differences, so as to meet the miniaturization requirements of communication devices. [0003] In the known technology, laser direct structuring (LDS) is used to injection mold some special laser-activatable plastics into a predetermined body stru...
