New MK7 Reflow Oven for High-Throughput SMT and Semiconductor Applications
The MK7 reflow oven revolutionizes SMT and semiconductor production with innovative design and advanced engineering.
It integrates all key customer requests — including lower Delta T, reduced nitrogen usage, and extended preventive maintenance intervals — into a compact low-height system that ensures clear visibility across the production floor.
You’re invited to visit one of our three demo centers to run thermal profiles and collect data yourself to experience the MK7 reflow oven’s performance advantages. Alternatively, send us your most challenging PCB, and we will provide custom reflow soldering profiles and data tailored to your production needs.

✔ Maintenance-free design
✔ VOID-free reflow process with vacuum option
✔ Industry 4.0 compatible system
✔ Integrated Cpk software – free of charge!

Reflow Oven with New Low-Height Top Shell

The low-height top shell provides easier access for operators. All exterior panels feature dual insulation, reducing reflow soldering energy loss by 10–15%.

Industry 4.0 Compatible Reflow Oven

Part of the Internet of Manufacturing (IoM) concept — enabling smart factories, intelligent systems, and connected production through cyber-physical integration.
The improved low-height heater module delivers optimal airflow and uniform heating with the lowest Delta Ts. The Uniform Gas Management system eliminates net flow, reducing nitrogen consumption by up to 40%. A new semi-circular heater design provides higher durability, greater efficiency, and a longer lifetime.

Revolutionary Flux Management System

The MK7 introduces a patented flux collection system that traps flux in removable jars — allowing maintenance during operation. The flux filtration box eliminates clogging risks, extending maintenance intervals. Additionally, the Flux-Free Grill system prevents residue buildup, ensuring maximum production yield and clean operation.

Green Flux Management – Low Temperature Catalyst

The integrated low-temperature catalyst system decomposes flux into harmless CO₂ and H₂O without producing any harmful byproducts. It requires no additional power or cooling, reducing operational costs. The catalyst also lowers oxygen concentration, which decreases nitrogen usage while maintaining target PPM levels. As a result, the oven remains cleaner for longer, extends PM intervals, and increases productivity.

Reflow Oven CPK System

A three-tiered control system (Tier 1: Reflow Oven CPK, Tier 2: Process CPK, Tier 3: Product Traceability) enables manufacturers to improve quality and yield while reducing costs. Automatic data recording and traceability ensure that all reflow soldering parameters remain under control and within specification.
