Description

This entry-level convection reflow soldering system for electronics production has a compact footprint. The HOTFLOW ONE combines high thermal performance, a good cross profile and well-defined zone separation to deliver reliable soldering results. It is available in versions with 14 and 20 zones. Its design draws on 35 years of reflow technology experience and balances economic and technological solutions, giving a favourable price-performance ratio, high reliability and availability, and easy maintenance and cleaning.

The thermal concept uses convection modules at the top and bottom throughout the process. Preheating, the soldering zone and the cooling section are all equipped with top and bottom convection modules. Optimized energy transfer minimizes ΔT across the assembly and increases separation between zones, supporting stable, reproducible temperature profiles. Cooling is internal. The heating modules at the top and bottom are removable, which simplifies servicing and cleaning. The system also has low energy consumption, and integrated energy consumption management helps control it during operation.

Assemblies travel on a low-mass conveyor system with a width of 516 mm, supported by a low-mass center support that limits heat absorption by the transport components. For higher productivity, a double transport option is available with dual track conveyors of 2 x 230 mm, allowing two lanes of boards to be processed in parallel. Automatic chain lubrication keeps the conveyor running consistently and reduces manual maintenance.

The oven is operated from an industrial PC with a touchscreen, and an operating status display shows the machine condition at a glance. The user-friendly machine control software records process data for traceability and quality monitoring. Its Autoprofiler function determines temperature profiles quickly offline, so new products can be set up without interrupting production. The software also includes order management for organizing production jobs and online help for operator support.

This combination of compact construction, top and bottom convection, energy-efficient operation and practical maintenance features makes the HOTFLOW ONE suitable for manufacturers introducing or expanding convection reflow soldering in SMT assembly lines.
