Seamark ZM-R7220A BGA Rework Station: The Ultimate Solution for Precision Optical Alignment

1. Unmatched Accuracy with an HD Optical Alignment System

Through a specialized split-optics prism mechanism, engineers can simultaneously observe the underside array of the BGA chip and the target footprint on the motherboard. This overlapping image is displayed in vivid clarity on a 15-inch industrial monitor. By utilizing high-precision micrometers for multi-directional adjustments (X, Y axes, and

angle rotation), aligning the chip perfectly with the PCB pads becomes effortless. Combined with an automatic vacuum adsorption mechanism, this BGA Rework Station achieves a staggering linear alignment accuracy of up to

mm. This ultra-precise placement entirely eliminates the risk of misaligned solder joints, bridging, or short circuits.

2. 3-Zone Independent Heating and Real-Time Temperature Monitoring

• Top Heater (1.45KW): Delivers precise hot-air flow directly to the top of the component.
• Bottom Heater (1.2KW): Supplies auxiliary hot air from beneath the board to balance thermal distribution.
• Large Area Infrared Preheater (2.7KW): Measuring 
  
  
  mm, this zone utilizes medium-wave ceramic infrared heating plates to evenly warm the entire PCB profile, drastically reducing local thermal stress.

An advanced closed-loop control system utilizing highly sensitive K-type thermocouples maintains temperature stability with a minimal margin of error of just

. Crucially, via its built-in 7-inch HD touchscreen interface, the BGA Rework Station offers a real-time temperature curve display and automatic profile analysis function. Technicians can easily program multi-stage thermal profiles (including preheating, soaking, reflow, and cooling stages) tailored to meet the exact specifications of both leaded and lead-free solder alloys. Once the reflow cycle concludes, an integrated laminar cooling fan activates automatically to cool the assembly rapidly and preserve the structural integrity of the components.
