The Heller 1826 MK 5 is a reflow oven with a belt and 10 zones. The Heller 1826 MK 5 series includes 8 top heating zones and 8 bottom heating zones. The Heller 1826 MK 5 series includes 2 cooling zones.[1][2]
What it is
The 1826 MK 5 is a forced-convection reflow oven equipped with a mesh belt conveyor and a total of ten process zones: eight heated zones (four above, four below) and two cooling zones. The oven is available in air and nitrogen atmosphere configurations. Overall dimensions are 183 by 54 by 63 inches (465 by 137 by 160 centimeters). Typical net weight is 4535 pounds (2060 kilograms). The maximum conveyor speed is 74 inches per minute (188 centimeters per minute). Maximum PCB width is 24 inches (61 centimeters).[1][5][2][4]
How it works
The 1826 MK 5 uses eight forced-convection zones, each with top and bottom nichrome open-coil heater modules rated at 6000 watts per zone. Temperature control accuracy is plus or minus 0.1 degree Celsius, with a cross-belt temperature tolerance of plus or minus 2.0 degrees Celsius. Two standard cooling zones follow the heated tunnel. The oven is controlled by an AMD- or Intel-based computer running Windows Vista or Windows 7, with auto-start software, data logging, and password protection. Optional nitrogen operation achieves minimum oxygen levels of 10 to 25 ppm, with typical nitrogen consumption of 500 to 700 standard cubic feet per hour. Profile change time is 5 to 15 minutes.[4][3]
Where it fits in the process flow
General reference — not yet source-verifiedIn a surface-mount technology (SMT) production line, the reflow oven is positioned immediately downstream of the pick-and-place machine. After solder paste has been printed onto the PCB pads and components have been placed, the populated board enters the reflow oven for soldering. Downstream processes typically include inspection (AOI, X-ray) and, if needed, wave soldering or selective soldering for through-hole components.

Frequently asked questions
What is the maximum PCB width the 1826 MK 5 can handle?
The maximum PCB width is 24 inches (61 centimeters) for the air version. The nitrogen version has a standard maximum width of 22 inches (56 centimeters), with an optional extension to 24 inches.[4]
How many heating zones does the 1826 MK 5 have?
The oven has eight forced-convection heating zones (four above, four below) plus two cooling zones, for a total of ten zones.[4][1][5]
What is the maximum conveyor speed?
The maximum conveyor speed is 74 inches per minute (188 centimeters per minute).[4]
What power supply is required for the 1826 MK 5?
The oven requires a three-phase 480 volt supply with a 100 amp breaker. Typical power consumption is 6.6 to 14 kilowatts continuous. Optional input voltages include 208, 240, 380, 400, and 415 volts at 50/60 Hz.[4]
What is the temperature range of the 1826 MK 5?
The standard temperature range is 25 to 350 degrees Celsius. An optional high-temperature configuration extends the range up to 450 degrees Celsius.[4]
What are the overall dimensions of the 1826 MK 5?
Overall oven dimensions are 183 inches long by 54 inches wide by 63 inches high (465 cm by 137 cm by 160 cm).[4]
