RE>DES: Punched via 10/31/96 Stella, There are a couple of punch houses in the US that my former company used for punching vias. The punched material was Kapton film, Duroid and LCP in thicknesses of 2-10 mils and the holes ranged from 2-6 mils. Design guidelines? Probably none except for specific aspplications. The company that provided this service for us was: NANTICOKE MICRO TECHNOLOGY Nanticoke, Pa. 717-735-3000 Hope this helps you.

Has anyone come across the Punched vias technology? Where is this technology commonly used? What are the design guidelines, I mean the annular ring and the small achievable mass-production holesize? And what are they limitations? Appreciate any information.
