Abstract
A BGA ball mount line with a dual in-line mounter flowing into one reflow oven and one in-line cleaner. The dual in-line mounter comprises a first ball mount cell and a second ball mount cell. The second ball mount cell is parallel to and a mirror image of the first ball mount cell. The first ball mount cell and the second ball mount cell can be run by a single operator located between them. In one embodiment of the invention, the BGA ball mount line with dual in-line mounters is implemented in three phases to provide a smooth transition. In the first phase, a proto-line is set-up with a first ball mount cell, a loading cell, a diverter cell, and an unloading cell, to optimize the first ball mount cell. In the second phase, a reflow oven and a flux cleaner are added to form a production line. In the third phase, a second ball mount cell is added to form a BGA ball mount line with a dual in-line mounter.
