Toaster Oven Reflow Controller

Introduction to the manually controlled toaster oven reflow december 14 2015 by robert keim with the help of a diy thermocouple measurement system you can use a cheap toaster oven to accurately reproduce a reflow soldering temperature profile.

Toaster oven reflow controller.

The classic ceramic heaters the ones you find inside your big kitchen oven and the newer quartz heaters. There are two kind of heaters usually mounted inside a toaster oven. External controller board can be used to control these ovens. That s where the reflow toaster controller comes into play.

No reflow oven controllers aren t. A reflow oven controller equipped with a display easy to program easy to operate with clear graphical feedback on every session for a fast and easy oven conversion get the complete kit easy wirings every needed connector supplied in the kit get dimensions a sketchup file and a user manual engineered for an easy mounting on a front panel. They are much cheaper than real reflow ovens but temperature cannot be set programmatically or accurately. Real reflow ovens are usually expensive like many other manufacturing tools but ordinary toaster ovens can be used in reflow soldering with few modifications.

While both of them can do the job of rising temperature high enough for reflowing quartz elements tends to heat up and cool down faster. It uses a k type thermocouple and unlike every other reflow controller we ve ever seen dirk is actually checking the accuracy of his temperature probe. All we aim to create is an embedded system that takes in temperatures and actuates a relay that controls the heating elements effectively controlling the temperature. By the way this reflow oven didn t work.

Runs on a pic 16f88 with boot loader pre loaded no programmer required. The unit comes as a kit with all the needed components for a fully independent system. Reeflow patent pending using tapconnect technology securely connects to the web allowing you to easily configure multiple heating profiles for your oven. If i placed ten boards in the oven inevitably.

There is also significant thermal inconsistency throughout the off the shelf toaster ovens as it is. To control the oven s temperature i created my own reflow toaster oven controller circuit. The problem i have with the oven pid controller combos i used was that the oven took too long to get up to temperature as it was on the two ovens i tried and then to cool down it took too long too.
