As all of you are well aware, Reliability Matters is all about reliability, specifically reliability of circuit assemblies. One challenge that seems to be persistent within our space is design for manufacturability, or DfM. If you’re a contract manufacturer, no doubt you’ve had the experience of being asked to build a product that seems unbuildable. One example that rings true was the introduction of bottom terminated components or BTCs. BTC’s are marvelous components. Because all the lead terminations are below the part, they permit highly dense component placement and highly miniaturized assemblies. They also presented a number of unique challenges in reflow, in many cases voiding, cleaning, and inspection. Like many other industries, we are not immune to the introduction of new technologies that may lack implementation knowledge. We then spend the next several years at technical conferences and symposiums learning us how to implement these new technologies. There are many acronyms in our industry that beg
