| I'm not sure about limits but perhaps underfilling the BGA might easy your mind. Treat the BGA as something similar to a flip chip and dispense underfill around the part. The rigidity gained by the cured underfill may be enough to alleviate some

I would recommend the following chemistries: Zestron Vigon SC200... Good but very $$$$ (703) 589-1198 Vertex (sold by Petrofirm and Alpha Metals)... Won't last as long as Zestron but must less $$$ (904) 261-8286 Kyzen... Also very good (800) 84

I require some feed back from any one who knows about using a voc free flux in a nitrogen wave solder machine soldering both through hle and smt componants. What disadvantages are there when using this flux? Do you have any contact details with any o

Glenn, There are both very good VOC-Free fluxes as well as alcohol based fluxes out there. This should be your primary focus if you are so lucky as to have to opportunity to actually select a flux! The use of nitrogen will benefit any no-clean pro
