What is the Reflow Oven？
Reflow oven is essential in electronics manufacturing, specifically for soldering components onto printed circuit boards (PCBs) through a controlled heating process. The oven uses temperature profiles to gradually heat and cool the board, ensuring the solder melts and solidifies effectively. This process ensures secure electrical connections and structural integrity for the manufactured product.
Choosing the Right Reflow Oven
Air Reflow Oven Best for General Applications
Air reflow ovens use convection to circulate hot air, making them suitable for a wide range of standard PCB assemblies.
Benefits: Cost-effective and widely available,ideal for medium to large-scale production where basic soldering needs are met.
Considerations: May not be optimal for highly sensitive components due to potential oxidation.
