Assemblers who have tried to resolve problems that stem from the rapidly growing array of advanced packages are getting some help from IPC with the newly released IPC-7093, Design and Assembly Process Implementation for Bottom Termination Components. This standard describes the critical design, assembly, inspection, repair, and reliability issues associated with bottom termination components (BTCs) whose external connections consist of metallized terminals that are an integral part of the component body.

Pockets of gas, or voids, trapped in the solder interface between discrete power management devices and circuit assemblies are, unfortunately, excellent insulators, or barriers to thermal conductivity. This resistance to heat flow reduces the electrical efficiency of these devices, reducing battery life and expected functional life time of electronic assemblies. There is also a corresponding increase in current density (as the area for current conduction is reduced) that generates additional heat, further leading to performance degradation.

As electronic devices increase functionality in smaller form factors, there will be limitations, obstacles and challenges to overcome. Advances in component technology can create issues that may have time delayed effects. One such effect is device failure due to soldering residues trapped under bottom terminated components. If the residues trapped under the component termination are active and can be mobilized with moisture, there is the potential for ion mobilization causing current leakage.
