What it is

The Heller 1707 is a reflow oven system for soldering assembled printed circuit boards. The Heller 1707 MK7 is a seven-zone reflow oven with air or nitrogen process gas options and a single cooling zone.[1]

The Heller 1707 MK III is a solder reflow oven with seven heating zones and one cooling zone. The Heller 1707 MK5 series is a small-footprint reflow soldering oven with seven top and seven bottom heating zones and one cooling zone.[4][2][3]

How it works

The Heller 1707 MK7 uses convection heating and supports air or nitrogen process gas. The Heller 1707 MK5 uses forced-convection top and bottom heating zones, instantaneous-response open-coil heaters, and a single cooling zone.[1][2][3]

The Heller 1707 MK5 includes flux collection and logging functions, recipe storage, profiling support, and process control software. The Heller 1707 MK7 includes integrated CPK software and a green flux management system, and it is available with nitrogen chamber, air, and vacuum options.[1][2]

Where it fits in the process flow

General reference — not yet source-verified

A reflow oven sits in the solder-joining stage of surface-mount assembly after solder paste printing and component placement. The oven forms solder joints on populated boards before the assemblies move to inspection and downstream assembly handling.
