Abstract

This article describes a hand tool used to remove unusable semiconductor chips from a reusable substrate. The substrate is presented to the tool upside down on the rails 1 and 3. Plastic rails 1 and 3 are used to guide the substrate and to assure the correct height from the blade 5. The base plate 7 holds the rails 1 and 3 and the blade 5 in the correct position. The blade 5 is hardened tool steel set at a ten degree angle from the rails 1 and 3. This allows only the corner of the chips to contact the blade 5 causing them to pivot off. Also, this angle allows the blade 5 to hit only one chip at a time, making it easier to push the substrate through the tool. (Image Omitted)
