I've been thinking about this for a while. I've seen the infomercials about the NuWave Precision Induction Cooktop unit, and was wondering if I could set it to about 450° f and put the mainboard on it BGA side down and reflow the chips. Could this work ?

No, it's an induction cooker. https://www.cda.eu/hobs/how-does-ind...-cooking-work/

What diif said. ^
The induction cooker will only heat metal parts made of ferrous metals (i.e. iron, steel, etc.) Nothing else will react.
Also, the inductive field could (and very likely will) generate substantial currents through the PCB and possibly kill something on the board.
So again, that's a big NO.
Originally posted by diif View PostEven if it did transfer the heat, I think the weight of the board pressing down would deform the balls.
So even if this was not an inductive heater, but instead a regular IR/element heater, the answer is still, No, it won't work.Last edited by momaka; 06-15-2019, 08:15 PM.

Can confirm. An employee put a digital scale on the induction cooker when off. Something fell and hit the button to turn the induction cooker on. It was on for maybe a few seconds, that scale was completely destroyed.
I don't let anyone put anything other than a pot on the induction cooker anymore.
