Solder removal from semiconductor devices
A solder removal apparatus is provided. The solder removal apparatus comprises a plurality of solder-interfacing protrusions extending from a body by a length. Each of the plurality of solder-interfacing protrusions is configured to remove a corresponding one of a plurality of solder features from a semiconductor device, where each of the plurality of solder features has a height and an amount of solder material.
1. A solder removal apparatus, comprising:
a plurality of solder-interfacing elongated solid pins extending from a body by a length, each of the plurality of solder-interfacing elongated solid pins having an outer surface of solder-wettable material configured to remove a corresponding one of a plurality of solder features from a semiconductor device, each of the plurality of solder features having a height and an amount of solder material, wherein the outer surface of at least one of the plurality of solder-interfacing elongated solid pins has an area sufficient to support the amount of solder material of the corresponding one of the plurality of solder features.
2. The solder removal apparatus of claim 1 , wherein the plurality of solder-interfacing elongated solid pins are arranged in a first pattern corresponding to a second pattern in which the plurality of solder features of the semiconductor device are arranged.
3. The solder removal apparatus of claim 1 , wherein the length of each solder-interfacing elongated solid pin is greater than the height of the corresponding one of the plurality of solder features.
4. The solder removal apparatus of claim 1 , wherein at least one of the plurality of solder-interfacing elongated solid pins tapers from a first cross-sectional area closer to the body to a second cross-sectional area less than the first cross-sectional area further from the body.
5. The solder removal apparatus of claim 1 , wherein at least one of the plurality of solder-interfacing elongated solid pins has a greater surface area than that of a cylindrical pin having the same length and displacing the same volume.
6. The solder removal apparatus of claim 1 , wherein each solder-interfacing elongated solid pins is removably attached to the body.
