How to Control a Reflow Oven with Raspberry Pi


Here is a great Raspberry Pi based Reflow oven controller from “apollo-ng” on GitHub. You can edit your temperature curve on your browser and Rasberry Pi controls the solid state relays and fan.

Turns a Raspberry Pi into a cheap, universal & web-enabled Reflow Oven Controller. Of course, since it is basically just a robot sensing temperature and controlling environmental agitators (heating/cooling) you can use it as inspiration / basis when you’re in need of a PID based temperature controller for your project. Don’t forget to share and drop a link, when you do.

SMD Soldering Reflow Oven


Here is a nice tutorial on how to build your own reflow soldering oven using ControLeo2 reflow oven controller.

This particular instructable is based on the ControLeo2 reflow oven controller by Peter Easton. This is by far the best I’ve come across and the software is fully open source. It can control up to 4 solid state relays (SSRs), a servo motor (to open the door for cooling at the end of reflow process) and a buzzer. Most impressive is that it is self-learning. That means, it can adapt to your oven heating elements and their behavior. Thanks Peter for putting this out there! The electronics hardware design is based off Brian Barrett’s design. He is super helpful and I suggest reading his build guide (multiple times). Thanks Brian! 🙂

Making A SMD Reflow Oven


by packetbob @ instructables.com:

I decided to put together a toaster oven and wanted something that could handle large boards and possibly do small production runs. Doing a web search, you will find many options for toaster oven reflow controllers. They range from one-off designs to DIY boards to full kits. A large number of them are Arduino based. Some controllers just allow the oven to plug in (so you don’t need to take the oven apart) while others integrate completely inside the oven (more work but a much better product in the end).

Toaster oven reflow controller


by Henrik’s Blog @ hforsten.com:

Nowadays many of the most “exiting” chips come only in leadless packages, such as BGA and QFN which are hard or impossible to solder just by soldering iron, because leads are under the chip where they can’t be reached. These kinds of chips are usually soldered using reflow soldering. In reflow process solder paste is used instead of solder wire. It contains very small balls of solder in flux, diameter of the balls is just few micrometers. First this paste is put on the contact pads, then components are placed on the pads and whole board is heated in reflow oven where solder balls in the paste melt and attaches the components firmly in place.

Reflow Oven Controller with graphics TFT

This Reflow Oven Controller relies on an Arduino Pro Micro, which is similar to the Leonardo and easily obtainable on eb*y for less than $10, plus my custom shield, which is actually more like a motherboard.

As I believe it is not wise to have a mess of wiring and tiny breakout-boards for operating mains powered equipment, I’ve decided to design custom board with easily obtainable components.

The hardware can be found in the folder hardware, including the Eagle schematics and PCB layout files. It should fit the freemium version of Eagle

Hi, I recently built a reflow toaster oven using an Arduino. I know it’s pretty standard stuff, but my version has an automatic oven door opener (using a servo) and circulation fan to speed up the cooling time, and remote notification using an RF transmitter

How a Microwave Oven Works

Bill details how a microwave oven heats food. He describes how the microwave vacuum tube, called a magnetron, generates radio frequencies that cause the water in food to rotate back and forth. He shows the standing wave inside the oven, and notes how you can measure the wavelength with melted cheese. He concludes by describing how a magnetron generates radio waves.
