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, Yes, I was talking about the oven, but then thinking about Soltec in general and about things the software really should be able to do, got me worked up on the Deltawave. I guess the frustration with it's software is not far from the surface.

I was wondering if anyone has ever considered measuring the belt speed of their reflow ovens using some type of hand-held, preferably non-contact device? If so, could you recommend a manufacturer of such a device? We are considering measuring our act

kindly send me your reflow profile ---and also the PCB lay out i shall able to determine your process flow on speed....and glue application i can be reach at this email- rdm@magictek.com.cn my web site is ;www.magictek.com.tw we are furance maker w

If I read this correctly you have two identical ovens that were setup the same ie zone temps, fan speeds etc... when you ran the same board through each of them one showed a lower board temp. Is this correct? Is the temp of the board 7 deg. lower t

Yes, it is time and temperature, but it is also speed and distance. Even though you can run a longer machine faster, the boards have a longer distance to travel and you do too, so the cycle time per board may not improve be reduced as much as you th
