Hi there I have a question about reflow oven for Pb-free technology. I've noticed that some of the manufactures offer reflow ovens with short (26-30 lenght in cm) heat zones others offer longer more then 30 cm. So there are ovens with total heat len

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 all What do you think about soldering pb-free in reflow oven (air) lenght 1,7m (5 zones top,bottom) with max zone temp. 300C? Do you think that this process will be stable? Our max PCb dimension 260x260 mm. When i compare different oven producer t

We are in the process of launching a new product and found reflow solder issue with one of the inductors. I have set oven profile to paste specifications. I just finished profiling with thermocouple under problem component. All other components ex

BTU as well as most oven manufactuers have great products. If they fit what your looking for and can give you good support(preferably local) then you should not really see any quality problems with their products. With the oven max temperature of 300

Look to the no-Pb solderpaste mfr. specs for on-board temps. For example, Indium Corp. has a product that performs at on-board temps of 229C. Now, your BTU oven will handle this no problem, as will most modern ovens. Its all about thermal mass. Look

We're used to placing the theromcouple on the solder joint and securing it with thermally-conductive UV adhesive. It's quick & easy to apply, and I've only seen a couple degrees difference from high-temp solder technique. Thoughts?

That was the method we were going to try. We have the circuitry from a sifter we make. The sifter works with a regular speaker but I could not find one working at a high enough temp for an oven. Then I lost interest or got busy.
