Laser-machining polymers. |
摘要 |
<p>Article and method of making same by laser-ablation-machining of (a) aromatic and/or amorphous polyamide material, or (b) polymeric material having repeating in its polymer backbone aromatic rings and aliphatic chains (with the proviso that the aliphatic chains have at least 4 carbon atoms when the material is a polyester, and preferably in all cases U.V. laser radiation is preferred, preferably at wavelengths greater than 248 nm from a KrF or XeCl excimer laser. The preferred polyamides, polyetheresters, and polyimides have superior machining performance and may be useful for making uniaxially electrically conductive articles by machining holes cleanly through laminar sheets of the preferred polymers, which sheets aer subsequently metal plated.</p> |
