Abstract
A chip removal method and apparatus for use with a robotic unit. The chip removal apparatus includes a heated center quill and a soldering unit which cooperate together with a chip removal tool for simultaneously disabling the bonding materials securing a chip to a printed circuit board. The method permits the fine pitch chip device to be removed from the printed circuit board substantially intact for subsequent testing purposes.
