MK 1809 Reflow Oven
The ISO-certified Heller MK7 reflow oven is an advanced reflow system designed with several groundbreaking engineering concepts. The system integrates multiple customer-driven requirements, including lower Delta T on the board, reduced nitrogen consumption, and extended product maintenance intervals, all within a low-height design that allows clear visibility across the production floor.
The MK7 offers a highly customizable configuration with nitrogen chamber air and vacuum options, enabling flexible integration into different production environments.
Highlights
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.
Highest Yield and Efficiency!
✔ Lowest Delta T on the board
✔ Minimal nitrogen and power consumption
✔ Maintenance-free design
✔ VOID-free reflow process with vacuum option
✔ Industry 4.0 compatible system
✔ Integrated Cpk software – free of charge!
The low-height top shell provides easier access for operators. All exterior panels feature dual insulation, reducing reflow soldering energy loss by 10–15%.
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.
