The person you want to talk to is Dick Lucier 1-508-485-4680. 1] In our tests the material had 1/4 to 1/3 of the variation of the standard two ply laminate it was targeted to replace. 2] It costs a little more than high Tg material. 3] As for the most important criteria, tight registration jobs on thin cores. 4] If 80% is good enough you don't need to switch. I would use it for jobs requiring 4 core and below. These are terribly unstable and CL 200+ does have an advantage here. 5] Sorry can't help here. 6] It is more suceptable to handling damage. Because the glass is not woven you can peel the laminate if you try. ______________________________ Reply Separator _________________________________ Subject: Compositech CL 200+ Author: [log in to unmask] at corp Date: 5/10/96 5:08 AM Good day, ladies and gentlemen, I will appreciate if the users of the above laminates could comment on the followings: (1) The dimensional stability as compared to FR4. (2) The price premium to FR4. (3) What would be the most important criteria to consider for switching from FR4 to CL 200+ ? (4) It seems that if the yield is >80%, there is no reason to switch. (5) What would be its classification under NEMA's nomenclature ? (6) What are the pitfalls to observe when switching from FR4 to CL 200+ ? (7) Last, but not the least, will the manufacturer of CL 200+ please contact me personally via email. Just a gentle reminder that you wouldn't run into marketing your products in this forum. Thanking you in anticipation and have a great weekend.
