Abstract
The present disclosure relates to the method of manufacturing circuit having lamination layer using LDS (Laser Direct Structuring) to ease the application on surface structure for applied product of various electronic circuit and particularly, in which can form circuit structure of single-layer to multiple-layer on the surface of injection-molded substrate in the shape of plane or curved surface, metal product, glasses, ceramic, rubber or other material.
Claims5
A multi-layer circuit structure comprising:
- a curved substrate comprising an upper surface and a back surface;
- a first layer of a circuit pattern, the first layer formed on the upper surface of the curved substrate;
- a first layer of LDS paint formed over at least the first layer of the circuit pattern;
- a second layer of the circuit pattern, the second layer formed on the first layer of LDS paint;
- a second layer of LDS paint formed over at least the second layer of the circuit pattern;
- and
- a third layer of the circuit pattern, the third layer formed on the second layer of LDS paint, the third layer of the circuit pattern comprising a pad configured for coupling to an electronic device;
- and
- a circuit formed on the back surface of the curved substrate;
- wherein the curved substrate defines a through hole and the first layer of the circuit pattern is electrically connected with the circuit at a location that is proximate the through hole.
