BRAZE BONDED NAIL HEAD LEAD
A braze bonded nail head includes a nail head lead having a first end with first and second sides and a braze alloy preform coupled to the first side of the first end of the nail head lead The braze bonded nail head further includes a weld joint centrally located on the braze alloy preform and extending through the braze alloy preform to the first end of the nail head lead. The weld joint is formed through micro-tig-welding, in alternative embodiments of the invention, one of the nail head lead and the braze alloy preform may include at least one protrusion extending therefrom, while the other of the nail head lead and the braze alloy preforms may include at least one interfit element configured to interfit with the at least one protrusion.
Wire bonding methods and systems incorporating metal nanoparticles
Wire bonding operations can be facilitated through the use of metal nanoparticle compositions. Both ball bonding and wedge bonding processes can be enhanced in this respect. Wire bonding methods can include providing a wire payout at a first location from a rolled wire source via a dispensation head, contacting a first metal nanoparticle composition and a first portion of the wire payout with a bonding pad, and at least partially fusing metal nanoparticles in the first metal nanoparticle composition together to form an adhering interface between the bonding pad and the first portion of the wire payout. The adhering interface can have a nanoparticulate morphology. Wire bonding systems can include a rolled wire source, a dispensation head configured to provide a wire payout, and an applicator configured to place a metal nanoparticle composition upon at least a portion of the wire payout or upon a bonding pad.
SEMICONDUCTOR DEVICE AND METHOD FOR MANUFACTURING THE SAME
