Beautiful figures and workmanship.
Re: Figure 8. I have been taught that side by side with resistive element
out, kind of back to back billboard was preferable to stacking. I would be
very interested in your opinion.

Bob,
We've just approved a new procedure to be added to 7721 called Component
Modifications and Additions. It includes guidelines for all sorts of odd
ball component mod stuff. You can get a preview of this new procedure off
our web site at http://www.circuittechctr.com/guides/6-3.htm.

Subject: Scab-On Parts
I have searched IPC-7711 and IPC-7721 and have been unable to locate methods
of mounting extra components on a finished CCA (other than - perhaps- part
of Figure 20 in IPC-7721 Sec 6.1 page 7 of 10).
Is anyone aware of and acceptable "methodology" for accomplishing CCA
modification by adding various types of components.
I would like to consider:
Resistors and Capacitors
Various other shapes such as
Tantalum Caps
Potentiometers
SOPs
etc.
Thanks
