Resin content has nothing to do with acceptance class and UOS you can use any combination of glass styles/Resin contents to obtain the thickness objective. The need for resin content may be evident in designs with flow issues, construct vias, etc. Jeffrey Bush Director, Quality Assurance and Technical Support VERMONT CIRCUITS INCORPORATED 76 Technology Drive - POB 1890 Brattleboro, Vermont 05302 Voice - 802.257.4571 ext 21 Fax - 802.257.0011 <http://www.vtcircuits.com/> -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of "Sefika ÖZKAL" Sent: Friday, April 14, 2006 7:16 AM To: [log in to unmask] Subject: [TN] 106/1080 prepregs Hi Technetters, The resin content of 106 standard prepreg is higher than the other ones. Is it acceptible if I use this prepreg for boards with IPC6012-Class II? Moreover is it possible to use both 106 and 1080 prepregs (IPC4101/24) in the same board? Is it acceptible when IPC6012-Class II specification is considered? Regards Thanks, Sefika OZKAL Design Engineer ASELSAN INC. MGEO Division Address : Cankiri Yolu 7.
