Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conductive laminates with three-dimensional shapes, particularly those with curved surfaces, tend to deform under external forces, compromising their stability and functionality in applications like touch sensors.
Innovation Solution
A method for manufacturing conductive laminates involving the formation of a to-be-plated layer precursor on a flexible substrate, bonding it to a support, applying energy to create a patterned layer, deforming it into a three-dimensional shape, and performing plating to form a metal layer, with the inclusion of functional groups and polymerizable groups to enhance stability and adhesion of the plating catalyst.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conductive laminate with a three-dimensional curved surface is manufactured, then the laminate can be used in touch sensors with curved surfaces, but the laminate deforms under external forces
Solution Approach 1:
The support is deformed into a three-dimensional shape with a curved surface before the plating treatment is applied. This preliminary deformation ensures that the conductive laminate maintains its curved shape and resists deformation under external forces during subsequent use in touch sensors
Solution Approach 2:
The conductive laminate is formed as a composite structure consisting of a support (such as a flexible substrate) and a metal layer deposited on it. This composite structure combines the mechanical stability of the support with the conductivity of the metal layer, enabling the laminate to maintain its curved three-dimensional shape while resisting deformation
2Shape
If a to-be-plated layer precursor is formed on a flexible substrate and then deformed, then a three-dimensional curved shape is achieved, but the plating catalyst application becomes more complex
Solution Approach 1:
The to-be-plated layer precursor is formed on the flexible substrate before the substrate is deformed into the final three-dimensional shape. This preliminary formation allows the plating catalyst to be applied more easily on a flat surface, simplifying the overall process while still achieving the desired curved shape
Solution Approach 2:
The flexibility of the substrate allows it to be deformed into various three-dimensional shapes without compromising the integrity of the to-be-plated layer precursor. This parameter change (from flat to curved) is achieved while maintaining the functional properties needed for subsequent plating

AI summary
A method of manufacturing a conductive laminate includes extracting a long flexible substrate from a roll on which the flexible substrate is wound, forming a to-be-plated layer precursor layer on at least one main surface of the flexible substrate while the extracted flexible substrate is transported in the longitudinal direction, preparing a support, bonding the flexible substrate with a to-be-plated layer precursor layer to at least one main surface of the support, applying energy to the support with a to-be-plated layer precursor layer to obtain a support with a patterned layer to be plated, forming the support into a three-dimensional shape including a curved surface, and performing a plating treatment on the patterned layer to be plated to obtain the conductive laminate having a three-dimensional shape.
