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.

No delta T issues as I am not actually reflowing the component to the PCB. This is for moisture sensitivity testing as per JEDEC 020C Standard. Trying to duplicate a profile in the standard and am having trouble reaching a component ramp rate of 3

I am testing some BGA's (PBGA 30mm x 30mm) to evaluate the maximum ramp rate we can achieve in our reflow oven. Temperature is being measured at the body(top) of the component / not leads. After several trials (with various oven settings), the high

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

I have used the Chinese ovens that Manncorp is selling bought from another supplier and they can do the job. These will do the job. You can manufacture metal piece(plate) slightly tilted to collect the boards behind the oven(similar to wave soldering
