  • Patent number: 7932739
    Abstract: An apparatus for supporting BGA packages for one or more testing processes is disclosed. The apparatus includes a substrate member. The substrate member has a plurality of contact pads, with each of the contact pads being spatially disposed around a peripheral region of the substrate. The apparatus further includes a plurality of contact regions spatially configured on a portion of the substrate member. Each of the plurality of contact regions is numbered from 1 through N being electrically connected to respective contact pads numbered from 1 through N. The plurality of contact regions is configured to provide electrical contact to respective plurality of balls provided on a BGA package. The apparatus additionally includes a holder device coupled to the substrate member. The holder device is adapted to mechanically hold the BGA package in place to provide mechanical contact between the plurality of balls and respective plurality of contact regions.

  • Patent number: 7772030
    Abstract: A method and apparatus for the decapsulation of integrated circuit packages. The apparatus includes a support member, the support member having an open region and an adjustable device coupled to the support member. The adjustable device can be adapted to hold a BGA package such that a surface region of the BGA package is spatially disposed to face a decapsulation source and a plurality of balls on the BGA package remain free from contact from the decapsulation source and free from contact from a thermal source capable of causing damage to one or more of the balls. The decapsulation source is provided to subject a portion of the surface region of the BGA package for removal of the portion of the BGA package.
