What is the eco-friendly soldering solution offered by the NeoDen IN6 Reflow Oven?
Introduction
In today's electronics manufacturing industry, SMT has become the mainstream process. However, with heightened environmental awareness and increasingly stringent workplace safety standards, the harmful fumes (such as flux volatiles) generated during the operation of traditional reflow ovens have become a major pain point for R&D labs, maker spaces, and even small-to-medium batch production lines. How can one achieve a green, safe, and efficient soldering process without compromising soldering quality? The NeoDen IN6 Reflow Oven, with its innovative built-in soldering fume filtration system and precise temperature control capabilities, provides the perfect solution to this challenge.

I. Environmental Challenges in Modern SMT Soldering
Traditional reflow soldering equipment releases soldering fumes during heating. These fumes not only pose potential threats to operators' respiratory systems but can also corrode precision instruments and contaminate cleanroom environments. To address this, most factories must install costly and space-consuming external exhaust ducting systems.
Furthermore, rising global demands for sustainable manufacturing and regulations like EU RoHS and REACH impose stricter emission standards on production processes. Consequently, the market now requires an eco-friendly reflow oven that guarantees soldering quality without external exhaust—a true plug-and-play solution.
II. NeoDen IN6: Redefining “Green” Reflow Soldering
Since its founding in 2010, NeoDen has upheld the mission of “making SMT automation accessible,” dedicated to providing cost-effective, user-friendly SMT solutions for global hobbyists, engineers, and SMEs. The NeoDen IN6 Reflow Oven embodies this philosophy—it is not only a stable industrial-grade device but also a truly eco-friendly reflow oven.
1. Core Highlight: Built-in Soldering Fume Filtration System
This system efficiently adsorbs and decomposes harmful gases and particles generated during soldering without requiring any external exhaust ducts, ensuring a fresh, odor-free, and pollution-free working environment.
- No external exhaust needed: Eliminates complex installation, saving space and costs.
- Plug-and-play: Suitable for non-industrial environments like offices, labs, and home workshops.
- Aligns with eco-trends: Supports green manufacturing and helps businesses meet ESG (Environmental, Social, Governance) requirements.
Per the NeoDen IN6 user manual, the filter cartridge is recommended for replacement every 8 months (depending on usage frequency), ensuring simple maintenance and controllable costs.
III. Superior Performance: Precise Temperature Control + Full Hot-Air Convection = High-Quality Soldering
Environmental friendliness is just the beginning, soldering quality is the core. NeoDen IN6 makes no compromises in performance:
1. 6-Zone Full Hot-Air Convection Heating
IN6 employs a full hot-air convection design with 3 independent temperature zones each on top and bottom (6 zones total), ensuring uniform PCB heating. This effectively prevents issues like cold solder joints, solder balls, and component displacement caused by localized overheating or shadow effects.
- Heating method: Nickel-chromium alloy heating wire + Aluminum alloy heat sink
- Temperature range: Ambient ~ 300°C
- Temperature control accuracy: ±0.2°C (achieved with high-sensitivity temperature sensors)
- Heat-up time: Approx. 20–30 minutes
2. Intelligent interface with real-time temperature curve analysis
NeoDen IN6 features an intuitive color touchscreen for effortless configuration:
- Zone-specific set temperatures (displayed in black)
- Real-time temperature feedback (displayed in orange)
- Conveyor belt speed (5–30 cm/min)
Crucially, it supports connecting temperature sensors to generate real-time PCB temperature curves. Simply attach a thermocouple to critical solder joints on the PCB, place it in the oven, and view the actual reflow curve on the screen. Compare this with the solder paste manufacturer's recommended curve to quickly optimize process parameters.
Note: According to the manual, the panel displays the “heating unit temperature,” which is typically 20–40°C higher than the PCB surface temperature. Therefore, always calibrate the process using actual measured temperature curves, not just set values.
IV. Why is NeoDen IN6 particularly suited for R&D and small-batch production?
1. Compact and lightweight, desktop-level design
- Dimensions: 1020 × 507 × 350 mm
- Net weight: 49 kg
- Soldering width: 260 mm (compatible with most prototype boards)
2. Low power consumption, high efficiency
- Maximum power: ~2000W
- Normal operating power: only ~700W
Compared to traditional large reflow ovens, energy consumption is reduced by over 60%, significantly saving electricity costs over the long term.
3. Dual-sided soldering capability
For double-sided PCBs, the IN6 adjusts upper/lower zone strategies to complete side A reflow first, then flips the board for side B soldering. Its precise thermal management prevents component detachment on the already-soldered side A during secondary heating.
4. Multi-scenario Adaptability
- Single-sided, double-sided, and multilayer boards
- High-density components vs. sparse layouts
- PCBs of varying sizes/thicknesses (max height 30mm)
While the equipment offers adaptive capabilities, it is recommended to save dedicated process parameters for different board types (via the “TAB” function) for one-click recall.
V. NeoDen's Global Manufacturing Capabilities
As a Chinese manufacturer with 15 years of expertise in the SMT field, NeoDen possesses:
- 27,000+ square meters of modern production facilities
