Problems solved by technology

[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 because industrial sapphire is extremely expensive and has poor thermal conductivity

Embodiment 1

[0018] The first embodiment of the superconducting thermal 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 several copper foil circuit layers 3. Preferably, the thickness of the diamond-like carbon coating is greater than 3 microns.

Embodiment 2

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

[0021] The manufacturing process of the superconducting thermal glass substrate of embodiment 1 and embodiment 2 is:

[0022] 1) Cut the thin high-transmittance glass substrate into the desired shape first.

[0023] 2) 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 the item with the highest thermal conductivity known in nature, but coating The thickness is 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 and withstand voltage, excellent thermal conductivity, and the price of glass ...

Embodiment 3

[0026] The superconducting thermal glass substrate of the present invention can also use sapphire as a substrate, that is, the third embodiment of the present invention, which is also to uniformly coat artificial diamond-like carbon on sapphire by sputtering, evaporation or atomic deposition. 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...
