If you are using VOC free flux, then forced convection preheats are better at evaporating the water. That may be why you're getting the "splatter". Plus, forced convection preheaters are most efficient at thermal transfer. See if you can get one to p

I have some problems in sufficient preheating the pcb's. They splatter on the mainwave, causing solderballing. Less flux causes problems with the fill of the through- holes. We use a Delta Wave with 3 preheat zones, the first two are calrods the thi

Hi Ronald, We have both, 2x calrod on our leaded delta and calrod/convection on our leadfree, both are IR in 3th zone. Indeed, the forced convection is way more efficient, we can run it at 100deg C, where we would need 300deg C for the calrod for t

Thank you for your input. Indeed, I am using a VOC free waterbased flux.

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.

Hi all, Maybe someone have experience with Vitronics -Universal FULL IR Reflow oven 4816. We have to make choise between above IR and Panasert REF-A? Maybe some Electrovet is better than both of them ? Any opinion will be very much appreciated. Mi
