The Marvel of Reflow Ovens in Electronics Manufacturing
Reflow ovens are the unsung heroes of the electronics manufacturing industry. These machines, primarily used for reflow soldering of surface mount electronic components to printed circuit boards (PCBs), are a crucial part of the production process.Get more news about Get more news about

## The Working Principle
In commercial high-volume use, reflow ovens take the form of a long tunnel containing a conveyor belt along which PCBs travel. The PCBs pass through multiple individually heated zones, each of which can be individually controlled for temperature. Technicians adjust the conveyor speed and zone temperatures to achieve a known time and temperature profile.
## Types of Reflow Ovens
There are two main types of reflow ovens: infrared and convection ovens. Infrared reflow ovens use ceramic infrared heaters above and below the conveyor, which transfer heat to the PCBs by means of radiation. Convection ovens, on the other hand, heat air in chambers, using that air to transfer heat to the PCBs by means of convection and conduction. Some ovens use a combination of infrared radiative heating and convection heating, and are known as 'infrared convection' ovens.
## The Role of Nitrogen
Some ovens are designed to reflow PCBs in an oxygen-free atmosphere. Nitrogen (N2) is a common gas used for this purpose. This minimizes oxidation of the surfaces to be soldered.
## The Future of Reflow Ovens
With advancements in technology, reflow ovens continue to evolve. Companies like DDM Novastar are focused on offering quality machines for low to medium volume applications. All their products are designed, developed, and manufactured in the USA. When you buy from a manufacturer like DDM, you get a reliable source for Spare Parts, Repairs, and Upgrades.
In conclusion, reflow ovens play a pivotal role in the electronics manufacturing industry. Their ability to accurately control temperature and time profiles ensures the quality and reliability of electronic components and devices that we use daily.
