Abstract:
A method of providing electrically conductive bumps on electrode pads of a microelectronic substrate, and bumped substrate formed according to the method. The method includes: providing a substrate including first electrode pads and second electrode pads thereon, the first electrode pads exhibiting a first pattern, and the second electrode pads exhibiting a second pattern different from the first pattern; attaching first solder portions to a solder delivery head according to the first pattern, and second solder portions to a solder delivery head according to the second pattern, the second solder portions being larger than the first solder portions; after attaching, releasing the first solder portions onto the first electrode pads, and the second solder portions onto the second electrode pads; after releasing, reflowing the first solder portions and second solder portions to form, respectively, first solder bumps and second solder bumps on the electrode pads.
