Features/Benefits

Repeatable Thermal Performance
Closed-Loop Temperature + Flow Rate = Total Closed-Loop Heating

UPPER HEATER:
• 2000 watt high efficiency (patented) with PID control
• Integrated cool air bypass reduces package temperature and controls joint time over reflow.
• Mass flow controller regulates precise heat flow (accuracy and linearity +/-1% repeatability , .1% full scale).
• Calibration controls for temperature and flow rate at multiple set points.
• Thermocouple-based stabilization takes in to account the thermal mass of the heating system to refine heat output to component.

BOTTOM HEATER:
• Radiant IR panel bottom heater (high thermal uniformity), based on black ceramic high emissivity coating, dramatically increasing radiant energy.
• Preheat of board is temperature-based via IR temperature sensor of thermocouple
• Integrated automatic pcb and machine cooldown system; insures operator safety handling pcb, brings system back to initial conditions for process repeatability and aids in controlling joint time over reflow.
• Integrated pop-up pcb supports, pcb expansion control, and flexible position pcb edge supports

Multiple Field of View Vision System
Provides Enhanced, Accurate, Quick & Easy Viewing
• Field of view: 70mm; 125mm (optional)
• Nine (9) position viewing; four (4) corners, four (4) sides, and center
• High magnification is programmable or operator adjustable to enhance placement
• accuracy and to minimize operator interpretation. Motorized joystick control for quick
• and easy adjustment.
• Independent intensity for component (green) and board (white) to provide clear, fast,
• and accurate alignment

Closed-Loop Automation
Promotes Simple, Fast, Non-Operator Dependent Process Control
• Force placement control: the load cell indicates actual (real-time) and target
• setting (20-2000 grams).
• Programmed z and vision axis: component placement, pickup, flux/solder dipping
• and drop off.
• Motorized joystick theta and z axis control for quick and easy component alignment
• Vacuum sensor control: activates automatic component removal (eliminating solder
• squeeze out) and to monitor/maintain non-contact tip height for site cleaning.
• Temperature-based preheat: regardless of machine or board conditions, the non-
• contact IR sensor triggers when preheat setting is reached and monitors throughout
• the process.
• Modular software enables rapid implementation of complex motion, vision and
• process controls.

Proprietary Site Cleaning #0029.03.012
Non-contact vacuum removal
• Vacuum sensor automatically and continually adjusts tip height and compensates for
• variable residue solder volume.
• Closed-loop hot gas heats pads after component is removed.
• Non-abrasive, composite vacuum tip safely removes residual solder. Eliminates
• damage to pads and solder mask caused by contact-based methods.
• Micro components utilize micro contact tips without affecting adjacent dense area.

Custom Nozzle Design
Engineering design is critical to thermal process control
• Standard nozzles for conventional components
• Special nozzles for special attention to thermal control, joint temperature uniformity,
• limitation of heat to device or sensitive areas and production concerns. Air-Vac has
• designed and manufactured thousands of nozzles for BGA's, 01005's, connectors,
• QFN's, sockets, and more.

Auto Profiling Software
Automatic, easy one pass thermal profiling
• Simply set the target temperature and go.
• Preheat, soak, ramp, reflow, and cool down events are automatically run.
• After the profile is complete, then entire rework process (removal, site cleaning,
• replacement) is built automatically and ready to run.
