In the manufacture of substrates for accommodating both flip chip type bonding and wire bonding of chips, small pads of a tri-layer solder nickel aluminum metal are required, which are bonded to selected metal pads on the substrate. The tri-metal pads are typically arrayed in a rectangular pattern on the substrate surrounding a site for the locating of a chip which will be wire bonded for the pads. The device in this article cuts the required configuration and number of pads from a strip of material and locates the cut pieces on a substrate.
