. Another example is fine pitch BGA part pads need to be solder mask defined to secure the pad to the board to pass drop tests. It has been proven that during drop tests a BGA solder joint will survive better than the pad ripping off the PCB surface because the pad size is so small

(solder TIMs or sTIMs) in most high-performance computing (HPC) TIM1 applications. The IEEE Heterogeneous Integration Thermal roadmap states that new thermal interface materials solutions must provide a path to the successful application of increased total-package die areas up to 100cm2

. A good solder joint will be reasonably circular in shape and the size of the joints should be reasonably consistent throughout the device array

. I would say that any mfr. recommended pattern that is between the Least and Most density level is OK to use. The mfr. could have created a reference design and ran it through stress tests for solder joint goal reliability
