Key Features
Highlights Reflow Systems
- The heating zone concept enables process and energy efficiency to be maximized and guarantees the lowest energy and media consumption.
- Reduced, tool-free maintenance effort and extension of maintenance intervals through optimized process gas cleaning directly in the process room.
- Stable cooling performance with continuously adjustable fan units with active monitoring and easy cleaning of the modular equipment within the cooling zone.
- Exact nitrogen control through integrated lambda sensor technology and continuous real-time measurement of residual oxygen values.
- Process stability through monitoring software that detects the smallest deviations in the process gas flow.
- Fan units are gas-tight and maintenance-free for life.
Zone Concept
Fewer zones – fewer fan units – less consumption!
The number of zones has no influence on a good ΔT. The system is aligned according to the process and defined by the heating chamber length – not by the number of zones. A high air volume is important. SMT achieves this with few but powerful fans.
- Small ΔT with perfect heat transfer
- 3 parts preheat (3 min) plus 1 part peak (1 min) corresponds to the 4 min IPC-JEDEC/solder paste recommendation
Process Gas Cleaning
- Tool-free, easy maintenance from the front
- lowest consumption of consumer goods
- Process gas cleaning – ON THE SPOT
- Cleaning directly in the process room
- No extraction of process gases through piping necessary.
Cooling Concept
The cooling zone length and equipment (heat exchanger plates, optimized air baffles, etc.) can be flexibly selected. The cooling medium is supplied via an integrated cooling unit or an external cooling tower or the domestic water supply.
- Stable cooling performance, no loss of performance over the operating time thanks to the use of smooth cooling plates
- Cooling plates with long service lives and planned maintenance (cannot “clog up”), no replacement of the cooling plates necessary
- Easy to clean
Intelligent Nitrogen Control
The intelligent nitrogen control with optimal control behavior reduces nitrogen consumption to a minimum. A nitrogen parameter that can be used for traceability is provided.
- Lambda probe (automotive technology) in peak zone
- Continuous live measurement of residual oxygen values
- Probe replacement (calibration) in < 10 minutes
Process
Individual fan control in all zones
- Individually adjustable fan speed in each zone (process optimization for flexible profile settings)
- Increased energy saving potential
- Active fan monitoring
- Fan control is separate from the fan motors in the system (no thermal loads and therefore more durable)
