ABSTRACT:
A vacuum pickup tool (10) having a handle (16) and a barrel (22) mounted thereto with a tip (24) that is heated by a temperature control unit (114). The barrel (22) and tip (24) include a longitudinal axial bore (41) attached to an air source through connector (116) to provide vacuum through an axial opening (62) and the tip (24) to hold a Z-clip (74) to the barrel (22). Actuation of a trigger (28) deactivates the vacuum and simultaneously heats the tip (24) to solder the clip (74) onto a wire wrapped pin (64) inserted through a circuit board (66). A thermocouple (54) and controller 114 monitor and control the temperature of the tip (24) as preset by the temperature control (114) on an instrument assembly (96).
