Hi Small ovens work fine if the settings are correct and I seriously doubt 55cm/min is right. Profile it and speed down to around 35cm/min. Increase first zone to around 170 keep second at 208 but increase last to around 280 BUT profile to check it

Hi Armando Hotflow 7 is a big machine and one of the best Reflow ovens around (in my opinion), well suited for Lead Free. A typical 1.6mm board has the following settings for Lead Free SAC305 paste All Temperature settings are Top and Bottom Prehea

One more question. Is it realy worth to have reflow oven with nitrogen for lead free?. What are yours experiences? Greg

Make sure you find out that short to longer ovens are both Lead-Free capable. If you want respond here on what they say for future reference for people.

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

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

Need recommendations on brands and models of reflow ovens for lead free. Small benchtop for prototyping and short runs. Board size about 10" by 10". What works well? What to stay away from? Thanks for any input and advice.

Hi All We have run SMT process with SnPb but we’re installing some lead free components like capacitors and resistor lead free. After the reflow oven all components have good appearance with solder join sheen. But the lead free components the solde

Its not the max temperature that is the issue, its how much energy the oven is capable of transferring to the PCB inside the 4-6 minute window of a typical profile. In a conveyor oven this is achieved by having zones of different temperatures, but th
