Problems solved by technology

At present, thin-film circuits are all on a plane in terms of process production, that is, only planar thin-film circuits can be developed and produced; for example, in the announcement number: CN103579107A, the Chinese patent "A Method for Cutting Thin-Film Circuits Based on Mask Electroplating" ", the manufacturing method of the planar thin film circuit still stays in the engraved scribing process method, which can only be applied to the planar thin film circuit; if the manufacturing method of the curved surface thin film circuit can be realized in a real sense and can be achieved at low cost The mass production of is an issue that needs to be studied

Embodiment 1

[0032] A method for manufacturing a curved surface thin film circuit based on 3D printing technology described in this embodiment includes the following steps:

[0033] a. Set the base metal film, and set the base metal film on the curved surface structure; specifically, a thin film deposition layer can be deposited on the substrate through a thin film deposition process. The film deposition methods used in the deposition process include sputtering, Evaporation and chemical vapor deposition. In this embodiment, in order to obtain better uniformity, magnetron sputtering is used for coating.

[0034] B, coat photoresist, spin coat photoresist on the metal film that obtains in a step;

[0035] c. Use a 3D printer to print out a mask plate with a circuit microstructure; a curved mask plate can be produced according to actual needs.

[0036] d. Exposure, placing the mask plate on the curved surface structural member coated with photoresist for exposure treatment, and obtaining th...

Embodiment 2

[0051] The difference between the manufacturing method of a curved thin film circuit based on 3D printing technology described in this embodiment and the first embodiment is that after step f is completed, steps a to f are repeated to manufacture a multilayer curved thin film circuit structure. Utilizing the repeatability of the method in Example 1, the fabrication of multi-layer curved thin film circuits can be realized, which is not only possible, but also has high precision, and the microcircuit structure of each layer can be adjusted at any time before fabrication.

[0052] Likewise, this embodiment still possesses the advantages of Embodiment 1.
