Innovation Solution
A process involving positioning low-melting-point conductive sheets between a substrate and a higher-melting-point conductive sheet, heating the low-melting-point sheets to melt them, and applying force while cooling to mechanically attach the higher-melting-point sheet, allowing for precise control over the attachment of a thick, uniform conductive layer.

1Manufacturing precision
If plating is used to apply conductive material to a substrate, then a conductive layer is formed, but the process is expensive, time-consuming, and results in thin, inconsistent layers
Solution Approach 1:
The invention changes the physical state parameters of the conductive material by using it in sheet form that can be melted and solidified. This phase transition approach allows for thick, uniform layers to be formed by controlling the melting and solidification process, eliminating the thickness consistency issues and time constraints of traditional plating methods
Solution Approach 2:
The invention uses a composite approach by combining the substrate with conductive sheets of specific composition. The conductive sheets are designed with appropriate melting points and material properties to bond with the substrate upon heating, creating a composite structure that achieves both thickness uniformity and process efficiency
2Manufacturing precision
If plating is used to apply conductive material, then a conductive layer is formed, but thick layers cannot be precisely applied
Solution Approach 1:
By changing the form of conductive material from deposited plating to meltable sheets, the invention enables precise control of layer thickness. The sheet thickness can be precisely manufactured beforehand, and during the melting and solidification process, this thickness is maintained, allowing for accurate thick layer application without complex masking or control systems
Solution Approach 2:
The conductive sheets are prepared in advance with the desired thickness and dimensions before the bonding process. This preliminary preparation of the conductive material in sheet form eliminates the need for complex real-time control during application, simplifying the manufacturing process while maintaining precise thickness control

Implementation Method 1
The first conductive sheets are heated to melt the first conductive sheets. The first conductive sheets have a lower melting point than the substrate and the second conductive sheet; the substrate and the second conductive sheet remain in a solid state when the first conductive sheets melt.
Implementation Method 2
the first conductive sheets are cooled to an attached state in which the first conductive sheets mechanically connect the second conductive sheet with the substrate

AI summary
A process of applying a conductive material to a substrate includes positioning a plurality of first conductive sheets between the substrate and a second conductive sheet. The first conductive sheets are heated to melt the first conductive sheets. The first conductive sheets have a lower melting point than the substrate and the second conductive sheet; the substrate and the second conductive sheet remain in a solid state when the first conductive sheets melt. A force is applied on the second conductive sheet toward the substrate, and the first conductive sheets are cooled to an attached state in which the first conductive sheets mechanically connect the second conductive sheet with the substrate.
