Example Embodiment

[0017] 1. Example 1

[0018] The first embodiment of the superconducting glass substrate of the present invention is as follows: figure 1 As shown, it includes a glass plate 1, the surface of the glass plate 1 is coated with a diamond-like carbon coating 2, and the surface of the diamond-like carbon coating 2 is provided with a number of copper foil circuit layers 3. Preferably, the thickness of the diamond-like carbon coating is greater than 3 microns.

Example Embodiment

[0019] 2. Example 2

[0020] The difference between the second embodiment of the superconducting glass substrate of the present invention and the first embodiment is that the surface of the diamond-like carbon coating is plated with a silver-plated layer.

[0021] The fabrication process of the superconducting glass substrates of Embodiment 1 and Embodiment 2 is:

[0022] 1) First cut the thin and highly transparent glass substrate into the desired shape.

[0023] 2) Then, the artificial diamond-like carbon is evenly coated on the glass plate by sputtering method, evaporation method or atomic deposition method to form a diamond-like carbon coating; because diamond is known to have the highest thermal conductivity in nature, but coating The thickness is preferably more than 3 microns, and the thermal conductivity of diamond is 2000w / mk, which is five times that of copper. Therefore, the glass substrate has high insulation withstand voltage and excellent thermal conductivity,...

Example Embodiment

[0025] 3. Example 3

[0026] The superconducting glass substrate of the present invention can also use sapphire as the base material, that is, the third embodiment of the present invention, the artificial diamond-like carbon is uniformly coated on the sapphire by the sputtering method, the evaporation method or the atomic deposition method. the surface of the substrate.

Description

technical field [0001] The invention belongs to the technical field of glass substrates, and in particular relates to a superconducting thermal glass substrate. Background technique [0002] Traditional heat-conducting substrates generally use aluminum or copper as the base material. Once transparency is required, only PET flexible substrates can meet the requirements, but its thermal conductivity is extremely poor. Existing manufacturers use sapphire as the substrate, but industrial sapphire is extremely expensive and has poor thermal conductivity. Therefore, a substrate with high thermal conductivity, transparency, economy and practicality is required. Contents of the invention [0003] The object of the present invention is to provide a superconducting heat-conducting glass substrate aiming at the deficiencies of the above-mentioned prior art. [0004] In order to achieve the above object, the technical solutions adopted by the present invention are as follows. [00...
