Problems solved by technology

The disadvantage here, however, is that the head part has to be of complex construction and of larger design, since the supply and discharge lines for the tempered fluid require more space, and the contact plate itself must have a correspondingly larger size. size
This known plunger head is not suitable for very small electronic devices or arrangements where a plurality of plunger heads must be arranged closely side by side

Embodiment Construction

[0028] figure 1 A plunger 1, partly shown in an exploded view, can be seen in . The plunger 1 has a plunger head 2 which can hold an electronic component 3 on its front end by means of suction. In the illustrated embodiment, the device 3 is a device with an integrated circuit, IC for short, as in Figure 4 As can be seen in the figure, the component has a component body 4 and connection pins 5 protruding laterally from the component body. However, the plunger 1 can also be used to hold and move other components, for example BGA or QFN components.

[0029] The plunger head 2 can be placed on a cuboid base body 6, and is held on the base body in the lateral direction by spring tongues 7, each of which is fixed on the base body 6 by screws 8, and is held in the axial direction. Protrudes forward from the base body 6 in the direction. In this way, when the plunger head 2 is moved into a not shown centering device arranged in the vicinity of a not shown contact seat when the pl...

Abstract

The invention relates to a plunger for holding and moving electronic components in particular for introduction and removal of IC's to and from a contacting device connected to a test bed, comprising aplunger head (2) with at least one suction head (23) for suctional contact with a component (3) and a heat-conducting body (19), temperature-controlled by means of a fluid and arranged such that thesuction-contacted component (3) is in contact with the heat-conducting body (19). The suction head (23) passes through the heat-conducting body (19).

Description

technical field [0001] The invention relates to a plunger according to the preamble of claim 1 for holding and moving electronic components, in particular for transporting IC's to or from contacting means connected to testing means The associated contact means are removed and include a plunger head with at least one suction tip for holding the component and a heat conductor. Background technique [0002] Electronic devices, such as IC's (semiconductor components comprising integrated circuits), are typically tested for functionality prior to their mounting, for example, on circuit boards or other use. In this case, the component to be tested is brought into contact with a contact device, which is formed in particular as a contact seat and is in electrical contact with the test head of the test device, by an automatic handling device, usually called a "handler". . After the inspection process, the components are removed from the contact device again by means of the operator...
