Question:
If I have a solder paste that is 62Sn, 36Pb, and 2Ag, is
this a Eutectic or Plastic range solder paste? 63Sn/37Pb is
a Eutectic solder with a freeze point at 361 degrees "F".
I am using a ESP paste at the above mix. The range of this
solder is 354 - 372 degrees. If so it would seem to be a
plastic solder. If this is true then I need to readjust my
preheat temperatures at Wave Solder to compensate for the
354 degree low end of the solder paste to prevent reflow.
Is this paste Eutectic or Plastic? Has anyone experienced
this? Do I need a 62/36/2 paste like this? Why would a
regular 63/37 paste work?
