The HELLER 1936 MK5 is a hot air reflow soldering machine designed for surface mount technology production lines. It is built for lead-free soldering processes, with independent heating zone control to support customized temperature profiles for different PCB assemblies. The system is engineered for use in commercial electronics manufacturing facilities, supporting both small-batch prototype runs and medium to high volume production workflows.
This reflow oven model incorporates updated heating and cooling structures designed to reduce nitrogen gas consumption and electricity consumption by up to 40 percent compared with previous generation models. The system supports dual-track conveyor configurations with independent speed settings, and customers may select between air-cooled and water-cooled cooling systems based on their specific production requirements. The system is operated via a Windows 7 based control interface, with profile storage and real-time monitoring functions.

The 1936 MK5 reflow oven is configured with 10 independent top heating zones and 10 independent bottom heating zones, providing uniform thermal distribution across the PCB surface. The heated length of the system measures 3430 mm, supporting continuous conveyor flow through the soldering process. The cooling section includes 3 top cooling zones, which bring soldered assemblies down to handling temperature after the reflow stage. Each heating zone is fitted with independent heating elements and temperature sensors, allowing separate temperature setpoints for each zone to build precise soldering profiles.
The system delivers a temperature controller accuracy of ±0.1 ℃, with a cross-belt temperature tolerance of ±2 ℃ across the conveyor width. This level of temperature consistency supports uniform solder reflow across the entire PCB surface, for both small and large board formats. The conveyor system supports a maximum speed of 188 cm per minute, with adjustable speed settings to match different thermal profile requirements. Conveyor width adjustment is operated via manual motor control, with an adjustable PCB width range from 50 mm to 610 mm to accommodate different board sizes.
This reflow oven supports standard lead-free hot air reflow soldering processes, and is compatible with nitrogen atmosphere operation as an optional configuration. Nitrogen atmosphere operation reduces oxidation during the soldering process, for applications that require higher solder joint quality. The system also supports mixed technology PCBs that combine surface mount and through-hole components, as well as standard SMT only assemblies. It supports profile storage for multiple product recipes, allowing operators to switch between different board profiles with minimal changeover time.
The 1936 MK5 reflow oven is deployed across a range of industry sectors that require electronic assembly capabilities. This includes automotive electronics, aerospace electronics, and industrial electronics manufacturing, where consistent soldering results are required for high-reliability products. It is suitable for prototype development and small-scale production operations, as well as medium to high volume production environments that require consistent throughput and repeatable thermal performance. The system supports both single product runs and mixed product manufacturing setups.
The overall dimensions of the machine are W5890 x D1370 x H1600 mm, with a typical net weight of approximately 2900 kg. Installation requires sufficient floor space and ceiling clearance for the machine body, as well as access for maintenance operations. The system operates on a 480V, 3-phase power supply with 50/60 Hz frequency. Facilities planning installation must verify that their power infrastructure matches these electrical specifications.
Customers may select from multiple optional configurations based on their production needs. Available upgrades include a dual-lane conveyor design for higher throughput capacity, and a choice between air-cooled and water-cooled cooling systems. Nitrogen atmosphere capability is also available as an optional upgrade for facilities that require inert atmosphere soldering. Additional process monitoring tools and profile optimization features are available to support production line quality control for enterprise customers.
