Laser chem-milling method, apparatus and structure resulting therefrom |
摘要 |
The materials to be chem-milled are coated with a maskant material, a template having a specific hole pattern is then placed over the masked surface of the material. A laser beam is then directed towards the template and is scanned either manually or by numerical control means along the hole pattern. The laser is maintained at each hole for a sufficient length of time to enable the maskant to be burned from the material. The material is then chem-milled by any conventional means thereby forming holes through the material at the maskant free areas. The remaining maskant is then removed from the surface of the material. |
