SMT Reflow Oven - Mark7
The World's Best SMT Convection Reflow Oven for
High-Throughput Applications

The New MK7 platform revolutionizes the Reflow industry with several new and ground breaking designs! The MK7 incorporates all of the customer requests for lower Delta T, reduced nitrogen consumption and extended PM into a new low height package that makes it easy to see across the production floor.

We invite you to visit any of our three locations to run profiles and gather DATA for yourself to see the strong advantages of the MK7 for your production! Or if you prefer, send us your toughest board and we will run profiles and generate the data for you. We are happy to work with you to custom configure your system to suit your needs.

  • Highest Yields!
  • Lowest Delta T on the board
  • Lowest Nitrogen & Electrical Usage!
  • Maintenance Free!
  • VOID Free - with Vacuum option
  • INDUSTRY 4.0 Compatibility
  • Integrated Cpk software at No Charge!


New Low Height Top Shell
New low height top shell provides much easier access for operators. All skins have double insulation to save up to 10-15% in energy costs.

INDUSTRY 4.0 Compatibility
Internet of Manufacturing (IoM) - Smart factories, intelligent machines and networked processes through the use of cyber-physical systems.

Enhanced Low Height Heater Modules
Enhanced low height heater module provides the lowest Delta Ts on the product with better air flow and uniformity! The Uniform Gas Management system eliminates "net flow" which results in nitrogen consumption reductions of up to 40%! New semi-circular heater is more robust and efficient with much longer life time.

Revolutionary Flux Management System
Our revolutionary flux collection system traps the flux in collection jars that can be easily removed and replaced while the oven is running - saving time consuming P.M. The new flux filtration box also has no risk of flux clogging for a longer term P.M. interval. Additionally, our proprietary Flux-Free Grill system limits the flux residue on the cooling grills giving the Heller system the highest production yields of any oven!

Programmable Cooling
The new Big Flat Coil Cooling module provides cool rates of >3°C/sec. That rate meets even the most demanding lead-free profile requirements. Heller can also easily achieve slow cooling rate required by the flip chip process. Heller's unique design using a 10-inch (250 mm) long heater module provides more modules within the same heating length which means more process control and reduced liquid times.

Energy Management Software
Proprietary software allows you to program exhaust draw to optimize energy consumption during the various production times - heavy, light or idle. Energy savings of up to 10-20% have been realized!

Reflow Oven CPK
Heller provides dynamic 3 tiered system (Tier 1: Oven CPK, Tier 2 Process CPK, Tier 3 Product Traceability) enables customer to quickly improve product quality and yield while reducing costs. And the additional benefits of automatic record keeping and recall provide customers with the peace of mind that all process parameters are under control and within spec.
