Thad,

I think we need this book.

I can recommend Norm Einarson's "Bare Board PWB Design Manual". Refer to 
Jerry Cupples post of Oct 24, 95 copied below.

You may have seen a series of wordy posts on the need to pre-bake boards 
I
"contributed to". Well, Norman Einarson responded, and I counter-posted 
etc.

The only things we did not cover were the additional benefit of being 
able
to warm pizza in the baking oven, solderability of pepperoni, and whether 
capacitors taste better than anchovies.

Then, out of the blue last week came a phone call from Norm Einarson, 
which
my voice mail did not catch and I actually answered.

When he introduced himself, I half expected him to lambast me for my 
foolish position, but what ensued was a rather long winded but friendly 
conversation about circuit boards. I learned something. At the end, I 
displayed more ignorance by asking him what he did. He told me he was a 
consultant, lecturer, and writer, etc. and offered to send me a copy of 
his
latest book.

Today it came in the mail. "Bare Board PWB Design Manual" 1995, by Norman 
S. Einarson.

I took it home, and have leafed through all of it, reading several 
chapters. I have several other PWB related references, by Coombs and 
others. Although useful, these were written mostly for the fabricator 
rather than the designer and end user.

The Einarson book is concise, well written, and very current. I have not 
seen it at any of the shows - maybe I just missed it.

It has 7 chapters:

Complete Tooling Package
Bare Board Testing
Selecting Board Laminate Material
Controlled Impedance for High Speed Circuits 
Selecting a Surface Finish
Design Guides for Manufacturability
Calculating Bare Board Pricing

It is 158 pages long, has numerous figures and tables, and available (at 
a
reasonable $50) in paperback version from:

Printed Circuit Technology
P.O. Box 334
Burlington, MA 01803
617-272-0938

I apologize if this is commercial, but I fully intend to order a couple 
more copies for use in our Company (they _can't_ have mine). The writing 
style and content are a nice compromise between common sense and 
technical
detail. It is intended to "bring designers current with the fabricators 
and
identify the design cost drivers". I think it succeeds quite well.

I'm sure Mr. Einarson would not intend that someone post this (he might 
prefer just my 50 bucks), but I believe most would agree this is a timely 
and very useful reference for this business.
