Phil, I presume you are talking about the glass reinforced version by Rogers and Arlon's, lisenced from Rogers, CLTE. I last used in in a MLB design three years ago with mixed results mostly because of "nearly" qualified fab capabilities. The boards were designed using the ceramic material combined with Getek. The MLB's stayed together reasonably well but had some surface "flaking" issues based on not being able to determine cure. The stuff would readily come off when lightly sraped with a knife or other hard object. Trident was the board shop in Carson City, NV and Ambitech, I belive, was the other shop. Damn good R/F results though.
