Abstract
Official abstract text for this publication.
Provided are a liquid crystal polymer film (LCP film) and a laminate comprising the same. The LCP film has a first surface and a second surface opposite each other, and the first surface has an arithmetical mean height of a surface (Sa) less than 0.32 μm. The LCP film with proper Sa is suitable to be stacked with a metal foil, such that a laminate comprising the LCP film can have an advantage of low insertion loss.
First claim
Opening claim text (preview).
What is claimed is: 1. A liquid crystal polymer film, comprising a first surface and a second surface opposite each other, wherein the first surface has an arithmetical mean height of a surface (Sa) less than 0.32 μm and a maximum height of a surface (Sz) more than or equal to 1.10 μm. 2. The liquid crystal polymer film as claimed in claim 1 , wherein the Sa of the first surface is less than or equal to 0.31 μm. 3. The liquid crystal polymer film as claimed in claim 1 , wherein the Sa of the first surface is less than or equal to 0.30 μm. 4. The liquid crystal polymer film as claimed in claim 1 , wherein the Sa of the first surface is less than or equal to 0.29 μm. 5. The liquid crystal polymer film as claimed in claim 1 , wherein the Sa of the first surface is more than or equal to 0.028 μm and less than 0.32 μm. 6. The liquid crystal polymer film as claimed in claim 1 , wherein the Sa of the first surface is more than or equal to 0.028 μm and less than or equal to 0.290 μm. 7. The liquid crystal polymer film as claimed in claim 1 , wherein the Sa of the first surface is more than or equal to 0.028 μm and less than or equal to 0.289 μm. 8. The liquid crystal polymer film as claimed in claim 1 , wherein the Sz of the first surface is more than or equal to 1.10 μm and less than or equal to 7.30 μm. 9. The liquid crystal polymer film as claimed in claim 8 , wherein the Sz of the first surface is more than or equal to 1.10 μm and less than or equal to 7.239 μm. 10. The liquid crystal polymer film as claimed in claim 1 , wherein the second surface has an Sa less than 0.32 μm. 11. The liquid crystal polymer film as claimed in claim 1 , wherein the second surface has an Sz more than or equal to 0.8 μm. 12. A laminate, comprising a first metal foil and the liquid crystal polymer film as claimed in claim 1 , the first metal foil disposed over the first surface of the liquid crystal polymer film. 13. The laminate as claimed in claim 12 , wherein the laminate further comprises a second metal foil, and the second metal foil is disposed over the second surface of the liquid crystal polymer film.
