Ball land structure having barrier pattern

摘要

Disclosed is a ball land structure suitable for use with a semiconductor package. The ball land structure includes a ball land and a barrier on a core. The barrier may be configured to connect to the ball land so as to form a barrier hole between an edge of the ball land and an edge of the barrier thus exposing a portion of the core. A solder mask may be deposited on the ball land and a portion of the core exposed by the barrier hole so as to partially expose the core.
