The Heller 1809 EXL is a reflow oven used for surface-mount technology (SMT) board assembly. The Heller 1809 EXL features 9 top and 9 bottom forced convection heating zones. The Heller 1809 EXL can operate in air or nitrogen and has a temperature range of 25–350°C.[1][2]
What it is
General reference — not yet source-verifiedReflow ovens are machines used in surface-mount technology (SMT) assembly to solder electronic components to printed circuit boards by melting solder paste through a controlled thermal profile. The Heller 1809 EXL belongs to this class of equipment and is designed for high-mix, high-volume production.
How it works
General reference — not yet source-verifiedReflow ovens operate by conveying populated circuit boards through a series of heated zones, each controlled to a specific temperature, to gradually raise the board and component temperature, melt the solder paste, and then cool to form reliable solder joints. The thermal profile is divided into preheat, soak, reflow, and cooling stages.
Where it fits in the process flow
General reference — not yet source-verifiedIn an SMT assembly line, the reflow oven is positioned after the pick-and-place machine and before inspection or testing equipment. Solder paste is first applied to the bare board by a screen printer, components are placed by pick-and-place machines, and the populated board then enters the reflow oven to solder all components simultaneously. After reflow, the board typically goes to automated optical inspection (AOI) or x-ray inspection to verify solder joint quality.
