What is a Reflow Oven?
A reflow oven is similar to a convection oven you might have in your home. It has four stages of heating:

Preheat: The initial stage where the oven gradually raises the temperature.
Soak: The temperature is held steady to allow the solder paste to flow and wet the components.
Reflow: The solder paste melts and solidifies, creating a strong electrical connection between the component and the board.
Cooling: The assembly cools down.
Reflow ovens can be either convection-based (using hot air) or infrared-based (using infrared radiation). Both types have their advantages and disadvantages. Convection heating is generally slower and more uniform, while infrared heating is faster and more localized.

Considerations When Purchasing a Reflow Oven
Size: Consider the size of the PCBs you’ll be soldering and ensure the oven can accommodate them. Also, check if it fits within your shop or lab space.
Heating Method: Decide between convection and infrared based on your specific needs. If you need precise localized heating, infrared may be preferable.
