Arduino Solder Reflow Oven

A description of the theory behind the board and of the heating in the oven.

Arduino solder reflow oven.

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. Arduino triac power controller board. A circuit and an example of how to build it on a bit of perf board. When the oven heats the solder paste past the melting temperature the solder paste melts and solders the component to the circuit board.

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. 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. Diy reflow oven with reflowduino.

Having an arduino based reflow oven controller with a graphic lcd opens up a world of possibilities to solder surface mount devices. With this we are taking a big step closer to the finish of this project. The only high voltage electronics built in this project. Actually a diy solid state relay ssr.

The reflowduino is an all in one arduino compatible controller board that i personally designed and built and it can easily transform a toaster oven into a pcb reflow oven. To control the oven s temperature i created. The reflowduino is a completely open source arduino compatible wireless reflow oven controller packed with features. Arduino reflow oven 3.

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