SMT Reflow Soldering Oven Advantages

SMT reflow soldering oven is used for attaching different electrical components to the boards. In this process, the solder paste, which is a mixture of powdered solder and flux, is used for connecting the joints permanently. Standard ovens used for this purpose are much larger, and this makes these types of devices more convenient for different purposes, for example, in labs.

These devices are designed to provide maximum thermal performance with significantly reduced costs and less space needed. Thanks to the fact everything is computer controlled, there is no possibility for causing thermal damages to especially sensitive components, in any stage. Every device has four or more zones, individually controlled, and larger ones up to ten stages.

In the first stage, often called the preheat zone, the solvent in the paste begins to evaporate. In thermal soak zone the fluxes are temporarily attached. In the third stage, also called the reflow zone, the maximum temperature is reached. This temperature depends on the component with the lowest tolerance on high temperature.

The final stage of every reflow soldering process is the cooling stage. Gradual cooling is important for achieving the best grain structure of the solder joint, and manufacturers often advice the rate of approximately four degrees per second. Some other similar devices don’t include this cooling zone, but experts agree about its importance.

SMT reflow ovens are mostly categorized in mid to high volume devices, bench top models and nitrogen ovens. They are all designed to provide at least the same performance level compared to standard devices used for this purpose, but they do take up less space and provide very good performance.

Medium to high volume ovens mostly have at least four independent reflow zones, with at least three thermocouple inputs, to ensure the best performance and the best heat control. They are equipped with wide LCD screens, and stainless steel mesh conveyors. They can accept wide boards, and provide very good handling flexibility. Smaller models are very good for testing purposes.

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.

Larger SMT ovens provide up to ten controlled upper and lower full-convection heating zones. They provide maximum functionality, automatic hood-life mechanism and high precision conveyor mechanism. This is a reliable solution for all medium and high volume manufacturers. It combines high mass heat sources with efficient thermal heat transfer, ensuring very good process stability.

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.
