| I sometimes use a Silver Solder Paste that has small silver balls in it....
I only use it for soldering in places were it is hard to get at or with small SMT parts...
I just put small dab on the pins I need to solder or on the PCB and put the part into its place and apply a bit of heat and the Paste melts and then hardens... I believe the melting point of this paste is 220C and it works ok for what I use it for...
It isn"t that expensive ,well I guess it is compared to regular solder but it is about $5 for a 7g Tube....
