[tinwhiskers] - RoHS & BGAs!!!







































Hello All, 



I am in the hunt for information on how to best evaluate whether

underfill is needed for SAC BGA when soldered with SAC paste. ? ?



Also, part of my evolution is to find the right solder, flux and

chemistry to clean afterwards. Further specify a cleanliness level.



I guess one has to find to the right test to use to evaluate these

parameters. ? 



Our products are expected to last for 20+ years while mounted outside on

a power distribution pole mounts. ? ? ? ? ?





I can use all the help I can get. 



Thanks

Hani
