					Sniper & Sniper II Split Vision Rework Systems SMD-7000
Overview
The Sniper & Sniper II are BGA and Micro BGA Rework systems. One side of the Sniper removes the device, the other side
selects a replacement component; a monitor reflects the image of the bottom of the chip and the footprint on the board.
These are then adjusted to exactly overlay each other and the component placed automatically. The part is then reflowed.
