How To Build A Solder Reflow Oven - The Byte Sized Engineer | DigiKey
Переглядів 21,601
7 місяців томуIf you want to assemble a batch of PCBs with surface mount components you have a few options. You could use a regular soldering iron and magnification and do it all by hand. Or you could use a hot air reflow station to heat up the board and components until the solder melts. But if you have a lot of components or a large batch of PCBs to assemble this could get tedious. In this video I use an Arduino board, a thermocouple, and a solid state relay to build a solder reflow oven using a standard toaster oven. I use a TFT display with a touchscreen display to create a user interface that plots the solder reflow profile.

The knob is to keep you from putting it directly against the wall where it might overheat or start a fire.
@randycarter2001 7 місяців тому
My very first thought on the knob. There's only a single steel wall separating 400° inside with 72° outside.

If you are looking for a UKposts idea, I'd love a tutorial on tuning and programming a PID loop in the real world. Taht, after all, is where the magic is in this project. Without it there is nothing.

That UI is really slick, especially the graph-view.
@danielmatthews8475 7 місяців тому
Very nice Zach! I really like the fact that you didn't over engineer it. Last week I almost threw away the one I started a number of years ago because I still haven't finished it. I tried to make it too complicated. Yours is just right!
@bytesizedengineering 7 місяців тому
I make everything over complicated too. It's what makes us engineers! On an unrelated note, I have been wanting to try powder coating and this oven could also work for baking powder coated parts! Now you have a second use for that oven that you almost threw away!

Awesome project and video, thanks Zach!

I would add a vertical moving axis on the plot to know the current time of progress

Very cool indeed. Probably gonna make this! THANKS

Heat sink is usually required on the SSR when switching larger loads. See the device data sheet and read the nameplate on the appliance being switched. I'd rather gut the controls from the oven completely and just wire directly so that the over can't be used for food.. But keep the controller outside the oven enclosure where it's cooler. Mount to the outside with a hole for an inverted U duct with a pwm fan for the cooling profile.

Perhaps that knob is to prevent the hot back of the oven touching the wall behind?
@larrysmall3521 7 місяців тому
Or something to wrap the cord around. My oven has two knobs for storing the cord.
@emmettturner9452 7 місяців тому
Definitely for wall clearance.

do you have a schematic or wiring diagram available that shows how everything is connected
@Tree2Tool Місяць тому
Is there a schematic for this project?

Is there a manufacturer and part # for the oven you chose that you can share for this project?

I think any toaster oven that doesn’t have digital controls would work. I use an cheap 20$ walmart brand one with quartz heating elements. I mightve missed him mention it. But basically you just turn timer off on toaster and set it to max temp. The relay will keep rapidly turning it on off to regulate the temperature

Awesome :)

But what if we like tedious? The management thinks I'm amazing firnturning PWBs into PCB assemblies.
@richdobbs6595 6 місяців тому
I think I'll buy a new toaster oven for my food, and down grade my old toaster oven for this purpose.
@TheQuinto2010 6 місяців тому
Temp control would be more stable if you epoxied the thermocouple to a small mass like a penny or even a small piece of scrap PCB.

Its flipping SOUL-der not SOD-der for flip's sake! Good little example of PID Control though!

How do you pronounce Salmon?
@Bill_N7FTM 7 місяців тому
Uh, no. The "L" is silent. The name come from the old English word, souder.
@ChuffingNorah 7 місяців тому
@@Bill_N7FTM Sorry to disabuse you, but back home in dear Old Blighty, solder IS pronounced with an 'L'. For those who don't know, Blighty is that quaint little island off the coast of Europe which err... invented the English language! See Polder (Dutch Land reclaimed from the sea)!🤣😂😁
