Abstract
3층 BGA패키지는 상부 및 하부 BGA패키지 트레이스 사이에 배치되는 BGA Vss평면을 포함하며, BGA패키지의 외부 주변상의 상부 및 하부 BGA 패키지 Vss 트레이스를 또한 포함한다. 바이어는 BGA Vss평면을 상부 및 하부 BGA 패키지 Vss 트레이스에 전기적 및 열적으로 접속한다. 다른 바이어들은 BGA패키지의 상부 및 하부 표면상에 Vdd 및 신호 트레이스로 부터 Vdd 및 IC신호를 전기적으로 접속한다. BGA패키지 하부 트레이스에 접속되는 솔더 볼은 시스템 PCB상에 트레이스를 매칭시키기 위하여 결합된다. 주변 Vss트레이스, 바이어 및 솔더 볼들은 BGA Vss평면에서 전류흐름을 유지하는데 도움을 준다. BGA패키지내의 IC에 의하여 감소되는 전류를 위하여 저 임피던스 전류 복귀경로(및 그래서 감소된 접지 바운스 및 감소된 IC 신호 지연 시간)을 추가로 제공하기 위하여, BGA Vss평면이 열 싱킹을 제공한다. 4층 BGA패키지는 BGA패키지의 하부 표면상에서의 BGA Vss평면과 트레이스 중간에 위치하는 BGA Vdd평면을 더 제공한다. 대칭인 2개의 인쇄회로 기판 재료로 부터 제조되는 본 실시예는 IC전류 싱킹 뿐만 아니라 IC전류 소우싱을 위하여 접지 바운드를 감소시키고 종래 기술의 BGA패키지와 비교하여 열 분산에 있어서 거의 100%의 개선을 제공한다.
