The NeoDen IN12 is a newly designed and manufactured reflow oven with 12 temperature zones, a unique heating module, an intelligent control system, and a built-in soldering smoke filtering system. It is described as intelligent, innovative, compact, and high-performance.
Function Description
The IN12's primary function is reflow soldering, a process used to solder surface-mount components to printed circuit boards (PCBs). It achieves this through hot air convection, ensuring excellent soldering performance. The device features a built-in soldering smoke filtering system that effectively filters harmful gases, contributing to an eco-friendly and high-end use environment. The intelligent control system is designed for ease of use and powerful operation, allowing for precise temperature control and uniform temperature distribution. It also includes a professional and unique 4-way board surface temperature monitoring system, providing timely and comprehensive data feedback for complex electronic products. The system can store up to 40 working files for easy loading during operation and displays PCB soldering temperature curves based on real-time measurements.

Usage Features
- Energy Saving: Low power consumption, designed to meet ordinary civil electricity requirements. It is claimed that the electricity cost savings can enable the purchase of a second IN12 within one year compared to similar products.
- Heating Module Design: Unique design with high temperature control accuracy, uniform temperature distribution in the thermal compensation area, high thermal compensation efficiency, and low power consumption. It uses high-performance aluminum alloy heating plates instead of heating pipes, which are both energy-saving and high-efficient, significantly reducing transverse temperature deviation.
- Control System: High integration, timely response, low failure rate, and convenient maintenance.
- Heat Insulation: Protection design effectively controls casing temperature.
- Temperature Sensor: Smart control with high sensitivity temperature sensor for effective temperature stabilization.
- Mesh Belt: Custom-developed stainless steel B mesh belt, durable and wear-resistant, not easily deformed after long-term use.
- Drive Motor: Custom-developed drive motor based on B mesh belt characteristics to ensure uniform speed and long life.
- Sprocket Design: High-precision profile technology and unique support structure for the mesh sprocket effectively reduce PCB vibration in reflow zones, facilitating soldering of small components (e.g., 0201) and complex chips (e.g., BGA/QFP/QFN).
- Cooling Zone: Independent circulating air design completely isolates the influence of the external environment on internal temperature chambers.
- Fume Filter System: Optimized soldering fume filter systems, tested by dedicated airflow simulation software, filter harmful gases, maintain room temperature, reduce heat loss, and lower working power consumption.
- Cool-down Mechanism: Unique heating plate design ensures even cool-down once heating stops, preventing deformation and damage from rapid temperature drops.
- Internal Thermostat: Made of environment-friendly stainless steel with no peculiar smell. Inner sides are equipped with insulation cotton to prevent heat loss.
- Screen Design: Hidden screen design for convenient transportation and ease of use.
- Temperature Control Accuracy: Adopts imported chips, achieving ±0.5% accuracy.
- Adjustable Wind Speed: Adjustable wind speed in all heating and cooling zones to cope with various soldering requirements.
- Safety Features: The upper temperature cover is automatically limited once opened, ensuring operator safety. An emergency stop button and power on/off switch are present.
- PCB Guide Device: Exclusively designed to realize direct connection between the mesh chain and the conveyor.
- Indicator Lights: Tri-color light on top of the cover indicates temperature status: green for well-set temperature, flashing yellow for heating-up, and red for closed or faulty zones.
- Soldering Formula Management: Allows saving and loading of up to 40 soldering formulas, with options to modify file names and parameters.
- Fan Management: Adjustable wind speed for hot air in each temperature zone (HOT1-HOT6) and the cooling zone (COOL).
- Temperature Curve Generation: Connects a temperature sensor to the PCB to generate real-time temperature curves, which can be started, stopped, and cleared.
- Double-Sided Board Soldering: Supports hot air reflow soldering for double-sided components, with specific instructions for handling A and B sides to prevent components from falling out.
- Installation: Requires 220V single-phase power supply. Electrical wire should be no less than 2.5mm², preferably 4mm². Machine should be set in a standard SMT workshop, away from flammable and explosive materials. Exposed wire harnesses must be protected.
Maintenance Features
- Filter Element Replacement: The filter assembly needs to be replaced regularly, with a service life of 8 months (depending on service frequency). Instructions are provided for replacing both left and right filter assemblies, involving removal of screws, wind shields, and covers.
- Lubrication: Regularly add high-temperature lubricating oil to transfer chain bearings.
- General Precautions:
- Maintain a distance of more than 100mm when PCB size exceeds 100mm.
- Avoid opening the incubator unnecessarily. If opened, it must be supported by a rod.
- The upper cover and incubator can only be opened after the bottom caster is laid down.
- Do not touch the power board and control board when the power is on.
- Retest the plate surface temperature curve and adjust settings after changing chain speed, as it affects temperature.
