Claims
- 1. A tool for forming external electrodes at both ends of chip parts, comprising:
- first and second holding plates each having elastic material provided with a plurality of chip receiving holes passing therethrough from a front side to a reverse side of said holding plate;
- a guide plate against the front side of said first holding plate and having guide holes aligned with said receiving holes of said holding plates; and
- a spacer between said first holding plate and said second holding plate spacing the front side of said second holding plate from the reverse side of said first holding plate, the receiving holes in said second holding plate being aligned with the receiving holes in said first holding plate.
- 2. A tool as claimed in claim 1 in which said holding plates are each comprised of a flat plate portion having a plurality of through holes therethrough, and a frame member around the edges of said flat plate portion, said elastic material being provided on both sides of said flat plate portion and extending through said through holes and having said receiving holes extending therethrough and through said through holes.
- 3. A tool as claimed in claim 1 in which said holding plates are each comprised of a flat plate portion having a plurality of through holes therethrough and a vertical wall around the edges of said flat plate portion extending away from the front side of said flat plate portion, said elastic material being a body of elastic material against the front side of said flat plate portion and having the edge thereof against said vertical wall and having said receiving holes therethrough aligned with said through holes, said through holes being larger than said receiving holes.
- 4. A tool as claimed in claim 1 in which said holding plates are each comprised of a frame member and an elastic member held within said frame member and having said receiving holes therein.
- 5. A tool as claimed in claim 1 in which said guide plate has a tapered concave recess around each of said guide holes on the front side of said guide plate.
- 6. A tool as claimed in claim 1 in which said guide plate has a flange depending from an edge of said guide plate around the periphery of the reverse side thereof.
- 7. A tool as claimed in claim 1 in which said guide plate has a tapered concave recess around each of said guide holes on the front side of said guide plate and a concave recess around each of said holes on the reverse side of said guide plate.
- 8. A tool as claimed in claim 7 in which said concave recesses on the reverse side of said guide plate are tapered concave recesses.
- 9. A tool as claimed in claim 1 in which said spacer has a thichness for spacing the ends of the receiving holes in the reverse said first holding plate a distance from the ends of the receiving holes in the front side of said second holding plate which is less than the length of the chip parts in the direction of the length of the receiving holes.
