There are ledgitimate reasons for checking furnace calibrations, but let me clarify what that is. 1. TC's are not necessarily calibrted. Not unless you need "absolute" accuracy. TC's operate against a (non-linear) standard +/- a tolerance. Most

As long as you have a continuous profile with required soak and dwell periods, the zone lengths do not matter. For lead free, usually ramp to peak is preffered.that is with minimum soak (you can not avoid soak anyway. You can achieve the profiles irr

Hi, With regards to reflow oven or furnace, when conducting a temperature profile how does one determine how many points(Parts) on the pcboard to be measured/connected to the temperature profile. And how to determine what parts to measure? Than

Hi All Does anybody have done the profiling board life time experiment? What is the proper life time of FR4 profiling board? How can we know when the profile board or thermocouple should be change?How to use dummy board instead of using gold/real

I am working on a Substrate attach process. The package is gold plated, the preform is AuSn and the backing on the substrate is PdAg. I am using a Sikama reflow furnace. The profile has a 50 sec dwell time. I am over 280 degees C for a little over 1

I agree with Russ. The problem is your thermal isolation is so small 1/16 inch. Also, most ovens measure temperaure in the plenum. You don't solder in the plenum. Therefore, you have a intermidiate "zone" temp. mixing between the top and bottom

Well it depends on what kind of oven you have. If you have a short oven, you are going to have a difficult time. You will probably end up having several different profiles if that is the case. We have 3 BTU TRS 212 furnaces. They are fairly long 8 zo
