I concur with your second approach. A profile needs to be tailored to the design of the board, the components, and the solder paste. Your first approach seems to try to balance lower quality soldering with a lower process complexity.

Hi First I think you have to analize your PCB design. Heavy weight components should be gathered on one side of PCB. As I think, if you want to reflow both sides simultaneously there might be a problem. A chance that large components will drop off

Phil Zarrow wrote a useful paper that could help in evaluating paste. Here read it ... Evaluating Solder Paste � Not An Option Contributed by Phil Zarrow of ITM an Independent SMT consulting firm With soldering being the dominant source of assembly

I have the situation where we may need to use a variety of reflow temperatures. It seems that the design engineers want us to try a variety of "unspecified" pastes on the products. For example, the first PCB would be assembled using a higher temperat
