SMT Reflow Soldering Oven is a device used for connecting electrical components. It uses a special soldering paste made of flux and powdered solder and a computer controlled heat to attach the components to a board or the contact pads. Depending on the particular purpose, different models are available, including those designed for very small or sensitive parts.
These devices are generally used for different surface mount components. Using smaller, energy efficient and compact models provides reduced assembly costs. Computer controlled heat won’t cause any damage to even the most sensitive parts. The whole process consists of at least four different stages, or more.
In the preheat stage, the solvent in a mixture of flux and powdered solder starts to evaporate. In the next zone, the fluxes are only temporarily joined, but the highest temperature is reached in the third stage. This temperature will depend on the component which is most susceptible to thermal damage.
Cooling zone is important part of the process. In this stage, the board is gradually cooled, and the joints are solidified. A cooling rate depends on components sensitivity as well. Generally, the rate of four degrees of Celsius per second is the most commonly used. Cooling rates have a significant effect on solder joint grain structure.
There are different types of SMT soldering ovens, including medium to high volume models, the ones designed as bench top models, and also nitrogen based. Compared to standard devices designed for the same purpose, they provide lower energy consumption and take up less space. Compact and practical, they can find their usage in different processes.
With at least four independently controlled heating zones, medium to high volume machines are additionally equipped with numerous very useful things, including independent thermocouple inputs. Computer operated and calculated functions make these devices easy to operate and maintain. Smaller devices are often used for prototyping, for example.
Thanks to the large touchscreen, everything is clearly visible and easy to profile. It is simple to make a set of parameters and to save it for future needs. You can use the set as it is, or to adjust some parameters to suit your particular needs. For example, you could change only upper and lower limits and leave the existing conveyor speeds.
These compact sized models provide very good efficiency, easy handling and low consumption of energy. Advanced thermal management options and other innovative possibilities are making them very useful in all types of industries. Safety systems include audible and visual alarms and automatic shutdown options.
There are also much larger SMT ovens available, designed for high volume manufacturers. These devices can have ten individually controlled heating zones, and process wide boards. All heating zones are computer controlled and equipped with automatic hood-life and high-precision conveyor mechanisms. The device is designed to provide very good stability through all stages and energy-saving thermal heat transfer.
Different types of SMT reflow soldering oven with pin over mesh conveyor system meet any production requirement. Pin conveyors permit inline and double-sided processing. All components are built of high quality stainless steel, to maintain dimensional tolerances at the high temperature lead-free processing. All systems are equipped with special battery backup.
