Are your preheaters maxed out then? What is conveyor speed? anyway I would not have issue with that configuration at all. I have actually found that when using convection for some watersolubles you actually dry out flux and performance is worse.

Your Quality Manager won't let you make changes, yet you get blammed for process problems? First, you need a change in management. Second, if you can't change set pre-heat temps, change the conveyor speed. Slow it down and see if your joints loo

we worked out that the wave soldering cassettes Duratstone material takes alomst 35 degree away from the surface of the pcb, and the speed is already too slow it should be over 1.0 - 1.8 meters a minute but its now already 82 cm a minute, in order to

Chris, Thank you very much for your help.People from ETS were very kind to give us the access code. We have already exhaust control on the oven but seems like need to increase the outer fan capacity. I will let you know. Promissed to send you a nice

Doesn't make sense. Either your: * Oven is not operting properly [attach your profiler thermocouple to the baffle of each zone with a screw to check] ... OR * Conveyor speed is too high ... OR * Profiler is defective

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.
