Webtopics, such as area array packages--including BGA, CSP, and FC designs, bumping technique, assembly, and rework process,--and provides an increased understanding of the reliability failure modes of soldered SMT components. With cost effectiveness foremost in mind, this book is designed to troubleshoot errors or problems WebA correctly soldered joint should be clean, symmetrical, and have a concave shape compared to the neighboring joints. A defective solder connection will be disorganized and have a physical abnormality, like a swelled shape or a long stem. Here are the 12 Typical soldering mistakes and the resulting problems: 1.
