Air-Vac Engineering

Fast & Simple Operation
Removal: Locate nozzle over component, everything else is automatic (nozzle height adjustment, heating, vacuum sensing, removal, and drop off).
Site Cleaning: The vacuum sensor automatically adjusts to insure that the tip does not contact the board pads.
Replacement: Operator aligns component, then pick-up, placement, and all heating and cooling processes are automatic.

Repeatable Thermal Performance
Closed-Loop Temperature + Flow Rate = Total Closed-Loop Heating
• Calibration controls for temperature and flow rate at multiple set points.
• Upper Heater: 1000 watt high efficiency (patented) with PID control and 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 scales).
• Preheater: Radiant IR panel bottom heater, high thermal uniformity, based on proprietary design.
• 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.




Closed-Loop Automation
Promotes Simple, Fast, Non-Operator Dependent Process Control
• Force placement control: load cell indicates actual (real-time) and target setting (50-3000 grams).
• Motorized z and vision axis: component placement, pickup, flux/solder dipping and drop off.
• Vacuum sensor control: activates automatic component removal (eliminating solder squeeze out). Site cleaning non-contact tip height is accurately monitored and maintained.
• 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.



Accurate, Crisp Vision Alignment

Clear, fast, precise distinction of pads and leads
• Leica inspection-quality stereo microscope
• Green (component) and white (board) LED's with independent intensity
• Zoom lens with up to 2.75" component viewing
• Adjustable viewing angle allows ability to see reflow




Proprietary Site Cleaning
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 standard and custom nozzles for BGA's, 01005's, connectors, QFN's, sockets, and more.




Auto Profiling Software

Quick and 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.

Pivoting IR Probe with Laser Pointer #1012.02.017
• Provides process repeatability by insuring that the board is at the exact same target temperature each time before localized reflow begins.
• Operator is instructed to position the sensor at the beginning of the process.
• The non-contact temperature sensor monitors topside board temperature and automatically triggers the localized reflow process once the target is reached.
