Abstract

The embodiments described provide elongated bonded structures near edges of packaged structures free of solder wetting on sides of copper posts substantially facing the center of the packaged structures. Solder wetting occurs on other sides of copper posts of these bonded structures. The elongated bonded structures are arranged in different arrangements and reduce the chance of shorting between neighboring bonded structures. In addition, the elongated bonded structures improve the reliability performance.
