O.K., I give up. I am through trying to solder thermocouples on to 20 mil pitch QFPs. Whether it's my lousy technique (fairly likely), the wrong solder (Kester calls it thermocouple solder, and who am I to argue...it's a Sn10Pb88Ag2 alloy) or just

Steve, I'm using 5 Sn/1.5 Ag/93.5 Pb Solder wire with a melting point of 300 deg. C to connect my thermocouples on smd components for thermal profiling. I'm using a soldering iron with an adjustable temp. to be able to melt my solder wire. Temp is ab

I have been using aluminum tape to attach thermocouples lately. I got some when I ordered new thermocouples from KIC. I ran some comparisons using high temp solder and the tape, with no difference. You cut a small square of the tape (approx 1/8" s

Steve: Two things: 1 Chrys "The Thermo Princess" Shea wrote a great thread on attaching thermocouples that's in the SMTnet archives 2 Dymax (and probably others) makes a uV cureable thermal adhesive that's not a ugly to use as soldering thermal coup

Necessity is the mother of invention... The other day I loaned my last bit of high-temp solder to a co-op and never saw it again. Then I had to run a profile and I was in a pickle with no solder. So I ran out to the local Radio Shack to see if the

Hi Steve You really didn't tell us what is going wrong. Not enough heat to melt this hi temp solder (290C/554F)? Too much heat and burning up the pad/board? Thermo falling off? (remove all the original solder) You won't find Loctite 384 all that remo

Drag the iron and molten solder over the thermocouple to the left, encapsulating the bead. Now, obviously if you are left-handed, reverse everything. This is a foolproof way to attach thermocouples. I used to have a lot more difficulty with them u

Put "attach thermocouple" in the search box above and search "forum". Lots of hits there.

So I am reading about K type thermocouples in the IPC 7530 Guidelines and it says : "At temps above 250c it may suffer from temperature cycling hysteresis and may not be the best choice." Uhhh... It looks like the best choice is an N type thermocoup
