| titleOfInvention | Micropore manufacturing method suitable for liquid crystal polymer substrate |
| abstract | The invention discloses a micropore manufacturing method suitable for a liquid crystal polymer substrate, wherein the liquid crystal polymer substrate comprises a liquid crystal polymer layer and a copper layer which are attached to each other, and the micropore manufacturing method comprises the following steps: respectively preparing electrolyte solutions of a copper layer and a liquid crystal polymer layer; manufacturing a working electrode; respectively carrying out electrifying etching on the copper layer and the liquid crystal polymer layer by using the working electrode and sequentially adopting an electrolyte solution of the copper layer and an electrolyte solution of the liquid crystal polymer layer, and preparing the micropores; the electrolyte solution includes an etchant precursor and a constraining agent. The invention relates to a micropore manufacturing method suitable for a liquid crystal polymer flexible substrate, which can process micropores with small diameter and high depth-to-width ratio on an LCP flexible substrate; the problems caused by heat accumulation in the hole manufacturing process are avoided, and the good hole shape is ensured; meanwhile, the hole wall is coarsened, and the efficiency is high. |
