High Temperature Solder
Do not attempt to attach the TC by melting solder into the spot
and then shoving in the bead. Place the TC bead on the
attachment surface and heat both evenly with the soldering iron.
Make sure your iron is set to achieve temperatures over the
solder melting point. For the solder KIC provides 300 C should
be sufficient. Then touch the solder to the heated
TC bead and
let the heat from the TC bead melt the solder. This method
gives you superior wetting and a stronger solder attachment to
the pad or lead.
Be sure and remove any residual eutectic solder before
applying the high temperature solder. If the eutectic
solder is not removed, the tension of the thermocouple
wire may lift the component as soon as the eutectic solder
reaches it’s melting point, which is a lower temperature
than high temp. solder.
Your temperature reading will come from the first point of contact between the two wires leading from the
TC. To insure accurate readings, it is critical to carefully separate the two wires all the way up to the TC
bead after soldering.
High temperature solder is an efficient heat conductor, so if a tiny bit gets between the
TC bead and the
lead or pad; you will still get an accurate reading. However, too much solder at the measurement point will
increase the heat capacity of the
TC and cause your peak temperature measurement to read low.
