TI recommends following the recommendations provided by the solder paste supplier to optimize flux activity and to achieve proper melting temperatures of the alloy within the guidelines of J-STD-20. Processing the LMK6L-Q1 with the lowest peak temperature possible is preferable while also remaining below the components peak temperature rating as listed on the MSL label. The exact temperature profile depends on several factors including maximum peak temperature as rated on the MSL label, board thickness, PCB material type, PCB geometries, component locations, sizes, densities within PCB, solder manufacture recommended profile, and capability of the reflow equipment as confirmed by the SMT assembly operation.
