IR zone vs forced convection

Electronics Forum | Mon Oct 30 09:47:56 EST 2006 | pjc

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

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

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 everybody, now that lead-free is coming, I'm looking forward to change the oven we own in company I work for. Eternal question: what's the best oven technology on market. I allready know that we won't work with IR ovens, but I would like to have

thank you Grant and dreamsniper for these shared experiences; I think I'll still try some vapor phase just to have a look to this process, but will focus on a convection as long as it's the actually chosen technology in the company and that it's expe

Hi, cool news! I'll try to cook some as soon as I get some experiment material. Thank you for the test method. Rgds

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

Thanx a lot for advice... My only question is: did you had troubles with prehaeating of the boards? I heard it was the only critical point due to chosen technology, infrared preheat (if it's still IR). I allready checked Vitronics Soltec and IBL,

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.

We do not have problems with preheating. before we used to suspect that the cause of tombstone was that because the semi-auto and manual version do not have pre-heat stage. We had 1 with an IR heater and it is quite okay. you can use it too to cure a
