When the oven heats the solder paste past the melting temperature the solder paste melts and solders the component to the circuit board.
Arduino solder reflow oven.
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.
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.
Hello everyone this is a little demo of my finalized firmware for my solder reflow oven shield.
It sports a versatile atmega32u4 microprocessor with micro usb programming.
Arduino triac power controller board.
That concludes the soldering of all the wires on the arduino reflow oven controller board.

The only high voltage electronics built in this project.
A circuit and an example of how to build it on a bit of perf board.
A description of the theory behind the board and of the heating in the oven.
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.
