A system for testing semiconductor components includes an interconnect, an
alignment system for aligning a substrate to the interconnect, a bonding
system for bonding the component to the interconnect, and a heating
system for heating the component and the interconnect for separation. The
interconnect includes interconnect contacts configured for bonding to,
and then separation from component contacts on the components. The system
can be utilized with a method that includes the steps of bonding the
interconnect to the component to form bonded electrical connections,
applying test signals through the bonded electrical connections, and then
separating the interconnect from the component. The bonding step can be
performed using metallurgical bonding, and the separating step can be
performed using solder-wettable and solder non-wettable metal layers on
the interconnect or the component. During the separating step the
solder-wettable layers are dissolved, reducing adhesion of the bonded
electrical connections, and permitting separation of the component and
interconnect.
