for backward compatibility applications (such as this), the higher melting temperature alloy (LF alloy) gets the priority in selecting the reflow profile. you are using too low temps for reflow. your LF alloy wont reflow at these temp and you will e

I face a problem where the components termination is non lead free but solder alloy is lead free. Thus i am using hybrid reflow profile. The specs for the reflow profile i am using: reflow temp. 120 to 160 deg C; time 90 to 120 sec. As for the pak te
