Controleo3 DIY reflow oven
Default Controleo3 DIY reflow oven

I had been using a toaster oven, or hotplate for SMT stuff. Decided to spring for the Controleo3 MCU controller. Just ran the learning cycle and it works perfectly. You can use the controller for reflow or baking IC's.

The kit comes with solid-state relays, ceramic blanket, various other insulation and of course the touch-screen and MCU.

There's a servo which opens the door to cool the oven down -- much better than the "armstrong" method.

I was fortunate to only cut myself once in taking apart the Black and Decker oven.

Sa-weet! I've gotten tennis elbow from opening the door manually. :-)

While it's doubtful that I will do enough smd stuff in my lifetime to justify the cost, this looks like something the molecular gastronomy folks will eventually use to create the perfect cook on a bagel. So of course I'm in.

The servo on the door will make the cool-down period fit the profile.

That's really nice. I've been using the Rocket Scream shield + Arduino + converted toaster oven for years and really like it. But I manually control the cool-down and that part IS a bit of a nuisance. The Whizoo kits look really useful!

Whizoo gives you two "profile" examples -- these can be downloaded to Notepad and modified to fit the profile of the SMD paste you are using. In my case Chipquik leaded (keep it refrigerated.) These are then written to an SD card.

I did time and temperature for about 10 runs until I created a profile which matches the graph on the Chipquik datasheet.

The servo allows you to visit the gents while your board cooks.

oh, I rearranged my workspace to have one bench for builds and another for tests.

I switched back to leaded paste for the lower temps. Currently using Kester from OSH Stencil and I'm quite happy with it. Used Chipquik brand lead-free previously. Always refrigerated, warmed up >4hrs prior to use.

And don't forget to ventilate the room for the reflows! The ovens/flux put out quite a stench and plume...
