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

I can guarantee that vibrating ovens will be detrimental in double sided reflow for any of the larger parts. I find it interesting about BTU and there "vibrating" oven. I had a couple of these in the early days and they did indeed vibrate. However

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

I have a question for N2 reflow, I want to know how difference of the O2 PPM in reflow oven then get the result? Now, we use the N2 to purge into BTU oven and measure the O2 PPM is about 1,000. but cannot find the difference to compare to compress ai

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

The magnetic thing from the sot23 thread made me think of somthing from the past. Does anyone have any experience with vibrating boards during reflow? I know for a fact that if you vibrate a board during reflow it will alow the parts to "float" and

Here are some 5 zones models to look for: Electrovert OmniFlo5 Conceptronic HVA70 BTU VIP70 Vitronics SMR or XPM 520 Heller 1088 (4 zone)

I would reccomend at least a 8 zone system when doing RoHs. Most of the better systems (Vitronics, heller, BTU, ETC) built since 2006 should be able to run the higher temps for Pb Free. Should be a lot of them on the market world wide (used) with l

I would really suggest staying away from novastar on their ovens- we had a really bad experience with two of their ovens being unable to maintain temperature properly. We ended up buying a used BTU VIP70 and it has been working out great. A Heller 18
