I just sent out a board which I had quoted on FR4 and Rogers 4350. The Rogers material was more expensive, but for sure not 4x more. I won't get the boards back for a couple days yet, but I've seen other proto's they did for us (on .031" Rogers 4350 w/ immersion silver plating) and they looked good. The shop we used is Prototron. They have fabs in Redmond WA and Tucson, but I think maybe only the Tucson shop has the Rogers material in stock. I know for sure that it is only the Tucson shop that can do the immersion silver.

I'm currently searching for a U.S. fab for prototype quantity of Rogers' boards that doesn't charge 4X what I'm used to for FR4. I have some leads, but a lot of places I expected to be reasonable are not. Have you or others on this list found such a place? - Larry _______________________________________________ geda-user mailing list [2][email protected] [3]http://www.seul.org/cgi-bin/mailman/listinfo/geda-user References 1. mailto:[email protected] 2. mailto:[email protected] 3. http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
