Patent ID: 12012660

Abstract:
Disclosed is a method for manufacturing an LCP-based flexible copper-clad laminate, comprising: providing an LCP substrate and subjecting the LCP substrate to a Hall ion source pre-treatment; forming an ion-implanted layer in a certain depth range below the surface of the LCP substrate via ion implantation; performing plasma deposition to form a plasma deposition layer onto the ion-implanted layer; performing magnetron sputtering deposition to deposit copper ions onto the plasma deposition layer and form a magnetron sputtering deposition layer; and plating the magnetron sputtering deposition layer with a thickened copper layer to obtain the LCP-based flexible copper-clad laminate. Also disclosed is an LCP-based flexible copper-clad laminate, wherein a peeling strength between a copper foil and the LCP substrate of the LCP-based flexible copper-clad laminate is greater than or equal to 0.5 N/mm, a surface roughness between the two is smaller than or equal to 0.3 μm, a thickness tolerance of double-sided copper foil is not more than 4.3 μm, and a thickness tolerance of single-sided copper foil is not more than 3.4 μm.
