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?

Subject: [TN] Fab Drawing Note...


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-
