Bonding pads electronics

WebTypical wire bonding stations allow observation of the pads through a microscope that has a line of sight fixed at 30° from vertical. While respecting this observational constraint, it is possible to make a wire bond going from the device’s pads up to the receiving pad by rotating the part 60° between the two bondings. WebG. G.
