Most people do not intend to �solder� Type K thermocouples. They use solder to �attach� the thermocouple. Search the fine SMTnet Archives for a posting by Chrys Shea. 1 Common thermocouple types commonly used for thermal profiling are: * Type K �

| I am profiling a BGA for the first time and I am seeing temperature flucuations on the ramp and cool down from the thermocouple I have placed through the pcb and under the component. I am using a 5 zone convection oven.Any suggestions on the plobl

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

I second Dave's encouragement to use the archives. It's a wealth of info and the search engine usually get's me what I want the first time. By the way, Richard, are you soldering your thermocouple to a ball on the BGA with hi-temp solder? It'd hel

Alberto: Consider Dymax 911. It�s wave solderable and passes Cl ion, copper mirror, SIR, and electromigration tests. We have heard good things about Masterbond uV curables, but have not looked at them. 911 doesn�t cure very deep into the little d

| 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

| | I have an Electrovert UPK 660c fitted with IR preheats top and bottom. We assemble a large range of multilayer backplanes and I was wondering if there are any advantages in changing to convection preheats.Has anybody got any views on the subject.

| | | We recently made the switch to no-clean and the wurface mount is turning out beautifully. However, the wave solder process continues to put up a fight; we are getting a white residue on the surface of the PCB. The residue is not localize
