Errors: CEM-3 is similar the FR-4, it's a glass epoxy material. Difference is, FR-4 uses a glass fabric, whereas CEM-3 uses glass fleece (or felt). For copper cladded FR-4 you may still see the fabric structure, but CEM-3 is totally smooth and has no structure at all. — Preceding unsigned comment added by 203.198.92.79 (talk) 03:05, 4 August 2011 (UTC)
