Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a liquid crystal polymer film is used, then excellent dielectric properties are achieved, but the film is easily torn due to anisotropy making manufacturing and handling difficult
Solution Approach 1:
The invention uses a composite structure consisting of a liquid crystal polymer film base layer and a liquid crystal polymer coating layer. The coating layer is formed by applying a liquid crystal polymer solution or extruding molten liquid crystal polymer onto the film surface, creating a multi-layer composite that combines the excellent dielectric properties of the film with the enhanced mechanical strength provided by the coating layer.
2Reliability
If a liquid crystal polymer film is used, then excellent dielectric properties are achieved, but manufacturing and handling are difficult due to anisotropy
Solution Approach 1:
The invention changes the physical state parameter of the liquid crystal polymer from solid film to liquid solution or melt state during the coating process. By applying the liquid crystal polymer in a liquid state (through solution coating, gravure coating, screen printing, inkjet printing, or extrusion), the material becomes easier to manipulate and apply, and then solidifies upon drying or cooling to form the desired coating layer.
3Reliability
If a liquid crystal polymer film is used, then excellent dielectric properties are achieved, but handling is difficult due to anisotropy
Solution Approach 1:
The composite structure of the film plus coating layer provides improved mechanical strength and handling characteristics. The coating layer acts as a protective and reinforcing layer that makes the overall structure easier to handle during manufacturing and application processes while preserving the excellent dielectric properties of the underlying film.
