Cruise Control Brain Solder Reflow... in the oven.

Took my inop cruise control brain apart to reflow the solder and... I really can't solder worth a crap.
I looked online and kids nowadays are reflowing solder on X-Boxes with the oven so I gave it a try.
Baked my CC brain at 385 degrees for 8 minutes, put it back in and it works like a charm.
I forgot about the step where you cover the non-solder side with aluminum foil so all the little plastic boxes around the whatchamacallits look a little, uh... runny, but it WORKS. I couldn't believe it.

A similar thing (like the Xbox ATI/IBM chipsets that tended to run way too hot) is done to reflow the defective 8600M GT graphic cards on 2007/2008 laptops.

Got my asbestos speedo on fellas... and in my own defense I had TWO inop brains, so if it didn't work one was going in as a core exchange on a rebuild.

That's amazing! I too have an inop brain (when it comes to cruise control, both mine and the cars..)
I'm tempted, but I would have to do it when my wife is out or she will make me use an oven bag!! "First the kitchen table, now the oven..."
cheers

3rd on the best post. I will give it a try (With the aluminum foil) as soon as I can get mine out. That is one thing I really miss on this car. But the way the weather is going, the AC has to come first.
Thanks for the post,

I can easily believe people putting circuit boards in the oven for a bake have bad brains. Why not find a tech that can do surface mount repairs? Lots of things really don't like heat for extended periods.

Wow..
I guess if it works. 1 -2 minutes too long and I would think some of the sensitive components would fry. Kind of like russian roulette but glad its working for you.

Do you have to turn it over and baste it? Would a smoker work? Slow and Low? j/k!
But seriously it can reflow the solder (fixing cold solder joints) but also it removes MOISTURE! Moisture can easily be trapped in a PCB.

Take a read on temperature recommendations.

Agreed. Automotive or consumer electronics are not rated to withstand that kind of heat. My guess: it was pure luck..
