Sorry theres a mistake on previous question. It should be lead free component termination but non lead free solder alloy Sn63/Pb37. The reflow profile i am using : Soaking temp. 120 to 160 deg C; time 90 to 120 sec. Peak temp. 215 to 225 deg C; time 60 to 90 sec. The question is there any metallic joint between the teminals of the component with the solder alloy. Please advice.

Follow your component supplier recommendations.

For instance: Xilinx says their lead-free alloy for their BGA spheres is SnAgCu, and liquidous is 217*C and they want you to peak at 230 - 235*C for good wetting according to their reflow guidelines.
