ABSTRACT
This chapter presents an arranged collection of the most common defects observed in SMA. But before we begin, two issues need to be made clear:
Each group of problems and their probable causes are provided here based • on the author’s subjective assessment derived from his experience and consideration. Therefore it is obvious that a reader may have a different view on a given problem or that it may have another cause. Always and in each case, while examining a detected problem, one should • be open to investigating its various causes, including the less obvious ones. Nobody should limit himself or herself to the pieces of advice contained in this book; an open mind is the recommended approach.
