Steve, Lets break down your requirements, IPC-4562/7 CU W7-14DSS3 Your Requirement /X is the specification sheet number /7 Annealed- Wrought With the property requirements Foil Metal CU-Copper Foil Foil Type W-Wrought (rolled) Foil Grade 7-Annealed-Wrought Foil Thickness 14-14 oz (Yes that’s right 14oz or 18.90 Nominal Thickness) Bond Enhancement treatment D-Double-Sided bond enhancement Foil Profile SS-Standard Profile both sides Quality Classification 3- Self Explanatory I believe the 14oz layers appear to be thermal planes with epoxy fill reliefs prior to lamination. There are several board shops that can manufacture your product. Unfortunately, the issue will be certifying the 14 oz copper to the IPC-4562, most copper vendors that manufacture copper foils above 10 oz certifies to the ASTM B-152 Standard Specification for Copper Sheet, Strip, Plate and Rolled Bar and not to the IPC-4562 Hope This Helps ! What part of North Carolina are you flying home to?

Mornin' All! Only 12 more shopping days left until Christmas! I'm gonna have to cram all my shopping in the last 5-days. I'm flying home to North Carolina, and don't want to carry a bunch of presents with me. Enough of my shopping woes... Our board buyer asked me for some help this morning with a board she's trying to buy. She's having a hard time finding a fab vendor that will be able to comply with one of the notes on the fab drawing which is; "Layer 2 and 11 material to be IPC-4562/7 CU W7-14DSS3 Copper Foil." I don't know what that is, so I'm asking your help, and if you know of a fab vendor that can comply with this note, I'd appreciate any contact info. Thanks! -Steve- --------------------------------------------------- Technet Mail List provided as a service by IPC using LISTSERV 1.8e To unsubscribe, send a message to [log in to unmask] with following text in the BODY (NOT the subject field): SIGNOFF Technet To temporarily halt or (re-start) delivery of Technet send e-mail to [log in to unmask]: SET Technet NOMAIL or (MAIL) To receive ONE mailing per day of all the posts: send e-mail to [log in to unmask]: SET Technet Digest Search the archives of previous posts at: http://listserv.ipc.org/archives Please visit IPC web site http://www.ipc.org/contentpage.asp?Pageid=4.3.16 for additional information, or contact Keach Sasamori at [log in to unmask] or 847-615-7100 ext.2815 ----------------------------------------------------- --------------------------------------------------- Technet Mail List provided as a service by IPC using LISTSERV 1.8e To unsubscribe, send a message to [log in to unmask] with following text in the BODY (NOT the subject field): SIGNOFF Technet To temporarily halt or (re-start) delivery of Technet send e-mail to [log in to unmask]: SET Technet NOMAIL or (MAIL) To receive ONE mailing per day of all the posts: send e-mail to [log in to unmask]: SET Technet Digest Search the archives of previous posts at: http://listserv.ipc.org/archives Please visit IPC web site http://www.ipc.org/contentpage.asp?Pageid=4.3.16 for additional information, or contact Keach Sasamori at [log in to unmask] or 847-615-7100 ext.2815 -----------------------------------------------------
