What it is

General reference — not yet source-verified

The Heller 1707 is a reflow oven system used in SMT soldering lines to heat printed circuit assemblies under controlled thermal profiles. Reflow ovens of this class transport assemblies through heated and cooling sections so solder paste can melt and solidify in a managed sequence.

How it works

General reference — not yet source-verified

Reflow ovens of this class use conveyorized transport and staged heating to bring solder paste through preheat, activation, reflow, and cooling. Forced circulation moves heated process gas around the assembly so the board and components follow a controlled thermal profile.

Where it fits in the process flow

General reference — not yet source-verified

A reflow oven sits after solder paste printing and component placement in an SMT assembly flow. The oven creates the solder joints that permanently attach surface mount components to the printed circuit board before downstream inspection, test, and later assembly operations.

Applications

General reference — not yet source-verified

Reflow ovens of this class are used to solder surface mount components to printed circuit boards. Reflow ovens can also be used in controlled-atmosphere processes where oxidation control and thermal uniformity matter for sensitive assemblies and package substrates.
