Inspection and Failure Analysis of Bottom Termination Components

Bottom termination components (BTCs) are becoming increasingly common in assemblies due to their low cost and high performance. There are varying types of BTCs in the electronics industry, such as QFN, SOIC, and LGA, all of which are typical on assemblies. The defining characteristic of these components is that the terminations are flat on the bottom, therefore relying on solder paste to make the component to board connection. This means that the height of the solder is primarily determined by the volume of solder paste and the finished assembly might not have visible solder joints to inspect. As you can imagine, this makes BTCs very challenging to inspect, often leading to X-ray analysis for process control.
