    The 5 Best Reflow Ovens in the Market

    Reflow ovens have seen tremendous evolution over the years, starting from Infrared heating technology to more modern iterations of closed-loop convection. ELE Times brings to you the best reflow ovens in the market today:

    One of the most important constituents of a PCB Assembly line are reflow ovens. It is inside a reflow oven that the thermal processing of solder paste on PCBs take place. Reflow ovens come in almost shapes and sizes and are designed for both small and large scale operations. For large scale operations, which is our target sector in this particular story, the most commonly used reflow ovens are inline or conveyor belt ovens.

    Available from: Bergen Associates


    Inline reflow ovens are configured with a number of heating zones followed by cooling section(s). Depending on the length and throughput of the oven there may be few zones, 8 or less, or many zones, 12 or more. During the reflow process the zones are programmed with a thermal set point. This set point corresponds to the temperature the circuit board should be exposed to as it passes through that zone.  The program with the temperatures for all of the zones, as well as the belt speed, is referred to as “the recipe”.  The temperature that the board “sees” as it is processed through the oven is called “the profile”. The recipe is optimized to achieve the profile that the solder manufacturer has specified for the solder paste that is used on the board. A number of specifications are employed including a maximum and minimum peak temperature, Flux Activation Time (FAT), Time Above Liquidus (TAL), heating and cooling ramp rates, etc.
