Arduino Solder Reflow Oven

Having an arduino based reflow oven controller with a graphic lcd opens up a world of possibilities to solder surface mount devices.

Arduino solder reflow oven.

The only high voltage electronics built in this project. That concludes the soldering of all the wires on the arduino reflow oven controller board. The shield at this stage is compatible with the arduino uno as well as the arduino mega. 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.

Intermediate full instructions provided 1 hour 10 459 things used in this project. Hello everyone this is a little demo of my finalized firmware for my solder reflow oven shield. When the oven heats the solder paste past the melting temperature the solder paste melts and solders the component to the circuit board. Arduino reflow oven 3.

Actually a diy solid state relay ssr. To control the oven s temperature i created. It sports a versatile atmega32u4 microprocessor with micro usb programming. Arduino triac power controller board.

With this we are taking a big step closer to the finish of this project. The reflowduino is a completely open source arduino compatible wireless reflow oven controller packed with features. 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.
