Wave soldering however, has been the common method of soldering multi-leaded through-hole components onto a circuit board designed for surface-mount components. Reflow ovens meant specifically for the soldering of surface mount components may also be used for through-hole components by filling the holes with solder paste and inserting the component leads through the paste. Each segment of the oven has a regulated temperature, according to the specific thermal requirements of each assembly. Reflow soldering with long industrial convection ovens is the preferred method of soldering surface mount technology components or SMT to a printed circuit board or PCB. Heating may be accomplished by passing the assembly through a reflow oven, under an infrared lamp, or (unconventionally) by soldering individual joints with a desoldering hot air pencil. The solder paste reflows in a molten state, creating permanent solder joints. Reflow soldering is a process in which a solder paste (a sticky mixture of powdered solder and flux) is used to temporarily attach one or thousands of tiny electrical components to their contact pads, after which the entire assembly is subjected to controlled heat. ![]() With our reflow machines, you’ll make your life easier and you’ll save both resources and time.Example of reflow soldering thermal profile. You may be tempted to choose a “toaster oven” instead of a professional soldering oven, but you’re no longer required to make that compromise. Usually, the soldering made by the reflow oven is much faster compared to the manual SMD soldering, that’s why, NeodenUSA will help you to scale your business, spending your budget smart, without breaking the bank. No matter if you’re an engineer, hobbyist, business or a startup, our soldering reflow ovens will optimize your assembly line from all points of view. Neoden is one of the leading manufacturers that provide affordable reflow soldering ovens for different uses such as PCB assembly, now available in the US. Why Choosing NeodenUSA for Your Reflow Soldering Needs? The reflow zone ensures reflow for every soldered lead while the cooling portion lowers the temperature at a controlled rate for an even connection between components and PCBs. The preheat and soak zones involve heating the component and then maintaining the temperature, respectively. Plus, they offer high thermal transfer efficiency, more consistent soldering, and even heat distribution.Įvery oven has four main zones of the thermal profile: preheat, soak, reflow, and cooling. Reflow ovens for PCB assembly represent a significant upgrade over manual soldering of electronic components to PCBs in all measurable values. These types of machines have become popular because they streamline time and resources consumption. There are also homemade options, though they have limited functionality and longevity. Manufacturers can select from various sizes and types, ranging from miniature models to commercial ovens. The PCB reflow oven has become a staple of the electronics manufacturing industry due to its advantageous size, precision, and speed. When an operator places an electronic product inside the device, it precisely applies surface mount components to the printed circuit board (PCB). These machines vary in size from small boxy ovens to inline- or conveyor-belt-style options. A SMT reflow oven is an essential machine of the thermal processing of solder for electronics manufacturing.
