Abstract
A transport head (10) and a method for transporting flux and solder balls (50) to locations for bonding pads (46) on a workpiece (44). To transfer flux, a first pattern definition mask (12) is attached to the transport head (10) and allows selector pins (64) to fully extend and receive flux for transport to the bonding pads (46) on the substrate (44). To transfer the solder balls (50), pattern definition mask (12) attached to the transport head (10) defines locations that are to be populated with the solder balls (50). The transport head (10) transfers the solder balls (50) to the bonding pads (46) of the substrate (44).
