BGAs, QFPs and other fine-pitch devices can now be desoldered, removed and replaced with the BR720 lead-free rework station from Manncorp. Utilizing split-vision zoom optics with 22x magnification, real-time images of components superimposed on solder pads are continuously displayed on the system monitor. Perfect alignment is achieved when operator makes final X and Y micrometer adjustments with LED lighting providing high image contrast.

The processing stage includes controlled heat from three sources: hot air top and bottom – capable of lead-free temperatures of up to 350°C. Additionally, an IR underheater prevents board warpage by evenly heating the entire PCB. Accurate profile monitoring is assured with the use of the onboard independent K-type thermocouple port. The placement head with automatic Z axis removes, places and solders components without operator intervention.

The system includes a built-in vacuum generator, eliminating the need for an external air source while providing plug-and-play capability at any location throughout the production floor. It will accommodate large boards to 550 x 500mm (21.6 x 19.7). The BR720 is $14,995, which Manncorp officials claim is well under the market price for rework systems with similar capabilities.
