METHOD OF MACHINING TERMINAL BOARD

摘要

A terminal board provided with a plurality of terminals on which ball electrodes are to be formed, wherein after a plurality of terminals (4) are allowed to protrude from the surface of a board (2) covered with a resist film, the board (2) is held on a rotatable chuck table (17) with the resist film kept intact, and a cutter (19) is applied to the resist film-covered surface with the chuck table (17) kept rotated to machine a plurality of terminals (4), whereby machining is done efficiently and economically without shorting terminals to each other when the top of the terminal board where a plurality of terminals protrude in a very close manner such as an interposer (1) is adjusted to be uniform in height.
