Abstract:
1. Handling device for contacting an electronic component to a contact socket electronically coupled to a test head of a tester, wherein the handling device comprises a plunger for holding the electronic component, the handling device further comprising: a circulating carriage, a drive arm extending radially outwardly from a center axis to the circulating carriage, the plunger being fastened to the circulating so that the plunger is movable back and forth in its axial direction in a drawn-back position and radially outwards, an advancing mechanism having a pneumatic cylinder mechanism and a pneumatic cylinder movement mechanism in the form of a crankshaft mechanism, wherein the pnuematic cylinder mechanism has a pneumatic cylinder comprising a piston rod which is aligned with the plungers, wherein in the drawn-back position the rear end of the plunger is spaced apart from the front end of the piston rod, wherein the crankshaft mechanism is coupled to the pneumatic cylinder mechanism to displace the plungers in its axial direction so that the plungers is transferable from the drawn back position radially outwards into its front contact position, and wherein the piston rod of the pneumatic cylinder presses the rear end of the plungers forward in the contact position, exerting a contact pressure being controlled by the pneumatic cylinder.
