摘要： A main body of an apparatus for delivering shielding gas during wire bonding of an electronic device has a through-hole in the main body which is sized for allowing a capillary tip of a bonding tool to be insertable through the main body when performing wire bonding. At least one gas outlet located on a bottom surface of the main body adjacent to the through-hole is operative to direct an inert gas in a direction towards the electronic device. At least one gas inlet in the main body is operative to supply the inert gas to the through-hole and to the gas outlet.

摘要： Disclosed is a transfer device for holding an object. The transfer device comprises: i) a housing having a housing surface; ii) at least one inlet conduit having an inlet for introducing a gas into the at least one inlet conduit; iii) a plurality of sets of outlet conduits, each set of outlet conduits being in fluid communication with the at least one inlet conduit and having a plurality of outlets for directing the gas out of the outlet conduits. In particular, the respective outlets of the sets of outlet conduits are arranged in a direction along the housing surface and away from a centre region relative to the respective sets of outlet conduits, so that a laminar gas flow that is flows along the housing surface generates a pressure differential which creates a force towards the centre region to hold the object against the housing surface. A gang picker is also disclosed.
