Testing a 15x15 cm 400 W hot plate for SMD soldering

[@DustinWatts]

Could you post the link where you got it? Thanks!

[@CuriousScientist]

It is posted... it is on my website both in the article and under the part and tools section. Read the description.

@@CuriousScientist My bad... I read the description and visited your site. But still I overlooked it. I'm going to try again. Thanks!

Awesome video! Thank You!

[@CuriousScientist]

Thanks!

i am smt machine operator. this is awesome! you’re human smt(?)!!

[@CuriousScientist]

Thanks! Yeah, it feels like I am a human pick and place machine sometimes. 😄

Oh! It's seem good

[@CuriousScientist]

It is not too bad!

Would it be possible to cook with this thing? Or is it to slow to get 1l water to cook in 15 min?

[@CuriousScientist]

You can calculate if 400 W is enough to boil 1 liter of water in 15 min.

Assuming zero losses, starting at 25C and going to 100C. Hopefully I can still remember high school thermodynamics. You can calculate required heat transfer rate as P = m(Cp(deltaT))/t = (1kg)(4186J/kgK)(75K)/(15*60s) = 348W. if it had zero thermal mass and perfect heat transfer, then it is possible to boil 1L water in 15min with 400W. But in real life I suspect it would not be possible.

This guy does physics! I love the approach. I was doing the other way. I calculated how much energy is needed to bring the water to boiling point. 313.5 kJ. And then calculated the time required to get this amount of energy via a 400 W heat source. Roughly 13 minutes. So theoretically, it is possible, but as the big purple guy once said: "really is often disappointing."
