I wanted to like this book very much, but the deeper I look into it, the more disappointed I get. I keep telling myself that the title says "Basic", and perhaps the information I'm looking for will be found in an advanced, follow-on title. But, there are too many important basic details that are simply missing or mentioned only in passing.
I'll offer one example, of many possible. From page 118:
"Fiducials come in several different sizes and shapes. Figure 5-16 shows the old-style fiducials or targets. ... It is highly recommended to place at least three (or more) fiducials toward the extents of the board."
OK, there's a nice figure of an 'old-style'; but what would a 'new-style' fiducial look like? Its not shown or described. How big is it? Even the old-style figure is not dimensioned. Where do they go - where is the extent, and how close is "toward"? (The term 'extent' is never defined.) Fiducials are an elementary and necessary aspect of layout, and I expected to find at least a couple of pages on their use and definition. If you were depending only upon this book, it would be impossible to figure out why, how, when, or where to use one.
What's an aperture? What's a Gerber? You can't possibly get any more fundamental than that, but those terms aren't found in the index or in over 70 pages (out of the book's 260 total) of lists of terms and acronyms (which do, however, include such useful entries as: Sequential Electrochemical Reduction Analysis, Systems Network Architecture, and Geiger Counter?).
This profession needs a good introductory reference work, but I'm sad to report that this isn't it.
