RATIONALE
This report is a major update to the original one dated 1998. It is much more comprehensive in its scope and detail. The
main purpose is to condense information from a number of sources relating to the design of electronic modules. It is
especially useful for some new players on the automotive electronics scene who may not know how to sort the “wheat from
the chaff” and what to focus on.
