Thermo-Dryer BELTROTHERM

Product catalog summary

Overview: The Thermo-Dryer BELTROTHERM is designed for the production of PCBs, membrane switches, scales, and panels using phototechnique or screen printing. It is used for predrying and curing photosensitive inks and solder masks on flat or V-belt transport systems, as well as curing conductive carbon, silver, copper inks, and other thermal drying inks.

Field of Use: The system is applicable for tack drying and final curing of photoimageable solder masks, curing of carbon, silver, copper, and heatsink pastes, and curing of two-pack inks, resins, and isolation materials.

Technology: The curing process combines long-wave IR-radiation with circulating hot air. A conveyorized flat belt system ensures double-sided curing, significantly reducing curing times compared to batch ovens. For example, final curing of photoimageable solder masks takes about 8-10 minutes, while tack drying takes 4-5 minutes.

Control System: The system is managed by a PLC-Control with a touch screen panel, allowing for the storage of 10 programs and a print function for process control.

Technical Specifications:

Working widths: 610 mm / 24" or 760 mm / 30"
Belt speed: Adjustable, with specific speeds for different processes
Temperature range: Room Temperature to 250°C
Electrical connection: 400 V 3/N/PE 50 Hz
Power per module: Connecting power of 9.3 kW / 18.6 kW, working power of 4.6 kW / 9.3 kW
Air supply per module: 100 - 300 m³/h
Module dimensions: Length 1000 mm, Width 1000 mm, Height 1200 mm

Modules Available: Relaxing, Exhaust, Heating, Cooling, and Input/Output table modules.

IR Spectrum: The ceramic heaters in the curing channel operate at a temperature of 300°C, producing a wavelength of approximately 5 μm.
