Reflow Oven Controller - Soldering

Software to build a reflow solder oven using a cheap pizza oven.

Build using the xpcc microcontroller framework.

Hardware

• Cheap pizza oven (or similar)
• Solid State Relais (e.g. Fotek SSR-25 DA)
• SSD1306 OLED Display (128x64 px, 1")
• Pt100 temperature sensor (and LTC2984 measurement IC)
• High temperature wire (e.g.)
• 5V Power supply

Ui

The oven has two buttons

Start / Temperature button

This button starts the reflow process or increases the temperature by 5°C if the reflow process is already running.

Stop / Mode button

To stop a running reflow process press this button. If no reflow process is running the button is used to switch between the reflow modes (displayes in the upper right corner of the display):

• NoPb
• Pb
• Constant Temperature (e.g. T85 = 85°C)
