Can anybody suggest how can I achieve good solderability in convectional reflow oven If I reduced Convection Air Speed 80%. The whole purpose is to reduce 0402 LED tilting in the convectional reflow and the PCB having QFN with 60 to 120 sec soak, 30

picture of the problem would help people to speculate what you do wrong

I am pretty sure, you are looking into the wrong spot. Your paste is too much, or your part has very inconsistent narrow leads(that includes wrong pad design as well.)

I agree with Evtimov. What he didn't point out is that the surface tension of the solder would vastly overwhelm any force from air flow.

Hi, We have both Vapor Phase ASSCON semi auto as well as Soltec convection inline ovens. I must say we had no end of problems with Vapor Phase. We tried everything, and just could not totally eliminate tomb-stoning completely. We would always get a

Hi, I think you cannot go wrong with Convection. If you want to experiment with VP, just get some of the fluid and put it into a pasta cooker on a standard domestic hot plate. Have a basin full of cold water so after reflow you can lift the cooker a

Good morning, IR reflow is yesterday technology. IR heating principle has a lot of issues with heat transfer capability (shadow effect) and uneven PCB heating. To avoid this forced convection ovens were developed. Reflow oven for SMD soldering must
