A current design I'm working on requires that surface mount components be mounted on both sides of a PCB... Any ideas on how to solder them?
If I bought a hot air rework gun, would it heat the board enough that components on one side would fall off when working on the other side?
I've also seen solder paste available that melts at different temperatures. The low temperature ones seem to melt around 183 C, and the next grade up melts at 218 C, but that's 424 F, and the skillet I've got only goes up to 420F, according to the label. My toaster oven will supposedly go up to 500F, but I don't have much confidence in that.
