What it is

The Heller 2043 MK 7 is a reflow oven for SMT assembly.[1][2][3][4]

How it works

General reference — not yet source-verified

A reflow oven heats a populated circuit board through a controlled temperature profile so solder paste melts and then solidifies into electrical and mechanical joints.

Where it fits in the process flow

General reference — not yet source-verified

A reflow oven sits in the SMT assembly flow after solder paste printing and component placement.

A reflow oven follows placement so the board can be heated into the soldering profile that forms the final joints.

Applications

General reference — not yet source-verified

Reflow ovens are used for SMT soldering of assembled printed circuit boards.
