Arduino Solder Reflow Oven

That concludes the soldering of all the wires on the arduino reflow oven controller board.

Arduino solder reflow oven.

Hello everyone this is a little demo of my finalized firmware for my solder reflow oven shield. Arduino max6675 thermocouple amplifier and adc gnd 1 gnd 3 3v 2 vcc a1 3 d0 a2 4 cs a3 5 clk. Intermediate full instructions provided 1 hour 10 459 things used in this project. This reflow oven is built around the arduino pro micro an adafruit tft color lcd and around two solid state relays one for the heating elements and one for the convection fan.

To control the oven s temperature i created. Arduino triac power controller board. Having an arduino based reflow oven controller with a graphic lcd opens up a world of possibilities to solder surface mount devices. Actually a diy solid state relay ssr.

Basically to perform reflow soldering solder paste is placed on a printed circuit board and the components to be soldered is placed on top of the solder paste. When the oven heats the solder paste past the melting temperature the solder paste melts and solders the component to the circuit board. A description of the theory behind the board and of the heating in the oven. A circuit and an example of how to build it on a bit of perf board.

It sports a versatile atmega32u4 microprocessor with micro usb programming. The reflowduino is a completely open source arduino compatible wireless reflow oven controller packed with features. The only high voltage electronics built in this project. The shield at this stage is compatible with the arduino uno as well as the arduino mega.

With this we are taking a big step closer to the finish of this project.
