1505 Mark V Series – SMT Reflow Oven

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

With its features increases productivity, improves quality and reduces costs:

  • Small footprint - overall length (200 cm) is similar size to benchtop machines but is IN-LINE for maximum throughput!
  • 5 heated zones -allows for more precise profile definition than lab machines. Profiles can be sculpted for minimal liquid time of reflow.
  • Full convection heating top and bottom – gives the lowest ΔT across your PCB.
  • 20 inch max PCB width – the model 1505 can process the largest PCBs of any system in its class.
  • The 1505 can produce profiles similar to larger mass.

Enhanced Low Height Heater Modules

Enhanced flow heater modules with 40% larger impellar, blanket the PCB with heat for the lowest delta Ts on the toughest boards! Additionally, the Uniform Gas Management system eliminates net flow which results in nitrogen consumption reductions of up to 40%!

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 losts.

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 >3ºC/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.
