Why solder is attractive, as there also fluxless methods available like thermocompression bonding or adhesive joining? The liquid solder can accomodate for implanarities more than other bonding methods. Simple pick & place followed by a collective reflow process are prerequisites for low cost processes. To have no need for force during bonding is another advantage of soldering: e.g. for sensitive components with membranes or other fragile features as well as for 3D stacking.
