Difference between a hot air rework station and an IR-infrared BGA rework station

 

The main difference between a hot air rework station and an IR BGA rework station is the way in which the PCB is heated. A hot air rework station uses heated air to transfer heat from the tool-to-board interface to the solder balls, while an IR BGA rework station uses infrared light to heat just enough of each ball to melt it.

The next important difference is the type of temperature control: hot air rework stations use PID temperature control, while IR BGA rework stations use proportional pressure modulation (PPM). PPM is more precise than PID as it can monitor pressure changes within milliseconds. This means that you can react quickly when applying flux to a PCB or reflowing solder balls on a PCB by adjusting your PPM settings as required. With PID, this would take around 20 seconds per change due to the slow response times of most systems.

Another key difference lies in the airflow control systems; with hot air, no special airflow is required as no cooling is needed during the reflow process, as this is all done outside the oven chamber using an external fan that blows all areas evenly, regardless of whether they are close or far apart.

 

TECHNICAL DESIGN

The ONYX series, which has won design awards, combines a stable, innovative design in terms of both handling and construction. The ONYX 25 is designed to hold oversized PCBs safely and securely.

CIRCUIT BOARD PREHEATER

The preheater has a standard output of 3500 W with a surface area of 300×300 mm, which can be increased to 7000 W with a surface area of 600×300 mm using an additional preheater module. With this level of performance, the necessary temperature profile for excellent lead-free soldering results can be defined, even for oversized PCBs.

ONYX 25 MAIN FEATURES

  • AXLE CONTROL
    4 motorized axes, controlled in a closed control loop
  • DESIGNED FOR EXTRA-LARGE PCBs,
    for PCBs up to 520 mm wide, with no restriction in length thanks to the open design
  • POWERFUL TOP AND BOTTOM HEATING
    2000 W top heater; 3500 W 300x300mm per preheater module (max. 2)
  • UP TO 8 THERMOCOUPLE INPUTS
    to control the process temperature
  • AUTOMATIC RESIDUAL SOLDER REMOVAL
    Option for removing residual solder from the solder joint after desoldering a component
  • FLOW CONTROL IN THE CLOSED CONTROL LOOP
  • STANDARD ZEVAC GAS NOZZLES
  • PCB HOLDER
    for holding even irregularly shaped PCBs without the need for additional fixing
  • FORCE MEASUREMENT,
    Force measurement in closed loop for automatic pick-up, fluxing, placement and desoldering.
  • VISION
    The new MFOV VISION system allows the complete view of components up to a size of 75x75mm, the light intensity of the illumination with LED can be changed.

 

RESIDUAL SOLDER REMOVAL
With the residual solder removal option, the residual solder is removed without contact after desoldering a component, without touching and thus damaging the surface of the PCB. The land surface is cleaned and prepared for soldering a new component after flux and solder paste have been applied.MOVABLE SOLDERING HEAD
The combination of the open machine design with the movable soldering head allows free positioning in the X-axis without having to move the PCB. As the PCB remains in position, precise positioning of the component is guaranteed. For quick positioning above the work area.VISION-SYSTEM
The advanced MFOV VISION system is part of the standard scope of delivery of all selective soldering devices in the ONYX series. It allows the complete view of components up to a size of 75 x 75 mm, but also smaller ones with an edge length of 0.3 mm.FORCE MEASUREMENT
Force measurement is also standard on all selective soldering devices in the ONYX series. During placement, it protects sensitive components with a preselected contact force.REPEATABLE AND PRECISE AUTOMATION
The VISUAL MACHINES™ machine software developed in-house is the basis for fast and flexible profile creation. The profiles stored in the library and the performance features of the machine guarantee repeatable, precise selective soldering results.LEAD-FREE APPLICATIONS
All ONYX appliances from ZEVAC are supplied with a nitrogen connection as standard. This and the powerful top heating of 2000W and preheating of 3500W (7000W) provide the basis for reliable soldering results, even with lead-free operation.
