The flux type and solder would probably be specified in purchase documents (if specifics are necessary). If no specific flux or solder are specified then use your typical processes. IPC A 610 specifies the conditions your assembled product must meet, regardless of process method.

We may have a requirement to assemble to class 3. I have a copy of ipc-a-610 and my impression is that this is more of inspect to class 3 kind of thing. Does class 3 assembly have requirements for fluxes, solders etc etc Any input will be greatly appreciated.
