Abstract

The present invention relates to a new and improved device adapted for mounting semiconductor components to substrates. More particularly, the device includes a housing and a first member rotatably mounted to the housing. A first interface is formed between the first member and the housing. The device also has a second member mounted in the first member and movable in an axial direction relative to the first member between a first position and a second position. The second member has an engaging mechanism at an end thereof for engaging a semiconductor component. A second interface is formed between the first and second members. The device is also provided with a supplying mechanism for supplying pressurized air to the first and second interfaces so as to form a first air bearing at the first interface and a second air bearing at the second interface.
