Overview

 
 

Removal: Nozzle is positioned over the component. Everything else is automatic (nozzle height adjustment, heating, vacuum sensing, removal and drop off).
Site Cleaning: The vacuum sensor automatically adjusts to ensure that the tip does not contact the board pads.
Replacement: Operator aligns the component. Pick-up, placement, and all heating and cooling processes are automatic.

Features/Benefits

 
 
 


Repeatable Thermal Performance
Closed-Loop Temperature + Flow Rate = Total Closed-Loop Heating
• 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 & vision axis: component placement, pickup, flux/solder dipping, 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.

Robust Platform
Provides Continual/Long Term, repeatable Performance
• Cast frame supports boad carrier x/y movement and vision alignment system.
• Precision vertical mechanism includes die-set bearings and high-grade shaft to ensure long term accuracy.
• Manual mode utilizing stereo-microscope viewing, nozzle design and robust thermal performance allows rework on proesses where
operator intervention is required.


 
 

 
 


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.

Options
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.
