Heller
1913 MKIII
What it is
How it works
General reference — not yet source-verifiedA reflow oven uses a conveyor belt to transport assembled printed circuit boards through a controlled temperature profile.
The profile typically includes preheat, soak, reflow, and cooling zones to melt solder paste and form reliable solder joints.
Where it fits in the process flow
General reference — not yet source-verifiedIn a surface-mount technology assembly line, the reflow oven is positioned after the solder paste printer and pick-and-place machine.
After reflow soldering, the boards move to inspection, testing, or cleaning processes.
Applications
General reference — not yet source-verifiedThe Heller 1913 MKIII is used for reflow soldering of surface-mount components onto printed circuit boards.
Applications include electronics assembly for consumer, automotive, telecommunications, and other industries.
Why won't it start?
Documented failure modes, common issues, and field considerations.
- One source states: temperature control module NG.
- One source states: two motors removed.
- One source states: eight SSRs removed.
- One source states: the conveyor and width adjustment motors are removed.
- One source states: HC2 main control board NG.
- One source states: water cooling pipes and condenser are aging.
- One source states: the furnace in the high-temperature zone has poor sealing.
- One source states: the control circuit is severely aged and unusable, and the unit cannot be started or powered on.

Frequently asked questions
How is temperature uniformity maintained across the wafer load?General reference — not yet source-verified
Temperature uniformity is achieved through multi-zone heating, careful placement of thermocouples, and closed-loop control. The furnace tube is often designed with a constant-temperature zone where wafers are positioned, and the system may include a rotating or indexing boat to minimize gradients.
What safety features are typical for these systems?General reference — not yet source-verified
Typical safety features include interlocked doors, over-temperature alarms, gas leak detection, exhaust ventilation monitoring, and emergency shutdown procedures. Many systems also incorporate redundant sensors and automatic gas purging cycles to prevent hazardous conditions.
What is the typical temperature range for machines in this class?General reference — not yet source-verified
While specific numbers vary by model, machines in this class generally operate from moderate temperatures up to very high levels used for diffusion and oxidation. The exact range depends on the design and materials of construction.
