The Heller 2043 MK 7 is an SMT reflow oven. The Heller 2043 MK 7 has 13 heated zones on top and 13 heated zones on the bottom. The Heller 2043 MK 7 has a maximum PCB width of 22 inches.[1][2][3][4]
What it is
General reference — not yet source-verifiedA reflow oven is a machine used in surface-mount technology (SMT) assembly to solder electronic components onto printed circuit boards by melting solder paste in a controlled thermal profile.
How it works
The 2043 MK 7 uses convection heating with 13 top and 13 bottom heater modules, each 12 inches wide. A nitrogen-capable atmosphere with a uniform gas management system reduces oxygen levels to below 100 ppm. The oven includes a flux management system with collection jars and a low-temperature catalyst that decomposes flux residues into carbon dioxide and water. A built-in thermal monitoring system and energy management software control the process. The machine is Industry 4.0 compatible and runs on Windows 10.[2][3][4]
