Fast firing furnace

c.FIRE, the new release fast firing furnace is designed for burning out of organic solvents and sintering of metallization contacts and is suited for all common sorts of metallization paste.
The integrated 4-stage dryer delivers advanced and accurate drying results. The electrostatic filter and the VOC-condenser are integrated in the newly designed cabinet and allow for a reliable and energy efficient exhaust handling.
The firing section includes an optimized infrared radiation setup with improved lifetime stability and advanced firing profile capabilities.

• High heat-up and cool-down rates allow advanced process control and steep temperature gradients
• Swing doors with toughened safety glass allow for quick chamber access
• User-friendly interface with touchscreen and hinged keyboard for text editing
• Detailed continuous process monitoring and control ensure highest output quality
• Short-wave infrared radiators for a stable process environment with permanent function monitoring
• Single- or dual-lane versions
• Case water cooling and advanced thermal insulation for lowest facility heat footprint
• In-situ belt cleaning (brushes, optional: ultrasonic)
• Exhaust handling (VOC-handling and electrostatic filter) integrated in dryer
• Optionally available without integrated dryer

Processes

• Firing of front side metallization
• Alloying of rear side contact
• Overcompensation of n+ layer and gettering of metallic impurities (Al-BSF formation)
• Release of hydrogen from SiN-layer for passivation of silicon defects
• Drying of metallization paste
