Reflow Oven technology overview.
Used in the process of attaching electrical components to their corresponding contact pads, reflow oven technology mounts these components to their appropriate printed circuit boards. Reflow ovens contain a system of various heating zones that can be controlled on a zone-by-zone basis. In most cases these heated zones are followed by a controlled cooling zone. The components move through reflow oven technology on a system of conveyor belts allowing for stable control over cooling and heating processes.
Infrared heat through radiation is most commonly used in reflow oven technology. Ovens that use a system of fans to heat up areas of the component are called Infrared Convection Ovens. Nitrogen is a common gas used for this purpose as it ensures minimal oxidation on the surface of the item being attached through reflow oven technology.
Currently, Tekmart has a number of forced convection reflow ovens in stock that use fan-forced convection. Some use an impute gas source, nitrogen, to create this system of forced convection. These systems have an advantage over many as they produce a more controllable environment with higher airflow for consistency from zone-to-zone and from oven-to-oven.
There are two methods of directing the flow of gas within the ovens. A defined flow path oven moves the gas consistently in and out of zones not allowing gas to rest in a single zone. This prevents contamination by flux therefore ensuring the prevention of flux buildup allowing the machines to stay clean. The other option is a non-defined gas flow oven that does not ensure the transfer of gas from zone to zone. These ovens typically have flux cleaning issues. The defined flow reflow ovens ensure a clean process by consistently pushing gas from beneath each zone causing recirculated gas to be consistently purged into adjacent zones. As a result, this recirculated flow calls for a lower power requirement for each heating zone and an overall cleaner process and atmosphere.
When selecting and compering reflow ovens you need to take in and consider all aspects that affect the overall production process. Consumers should look into thermal performance, throughput, process gas, design of the conveyor, computer software, reliability and the amount of maintenance downtime.
Tekmart has a variety of reflow model ovens in outstanding condition and high efficiency including the Electrovert BRAVO 8105, Electrovert Omniflow 7, Heller 1700 XHL, Heller 1809, Senju SNR-725, Tamura TAP30-407PH, TAMURA TAR30-366PH and the Vitronics XPM3-1030.
