Package Substrate

WBCSP

(Wire Bonding Chip Scale Package)

Memory用ワイヤボンディング高密度パッケージ基板

金線で半導体チップとパッケージ基板を接続し、半導体チップのサイズが基板面積の80%を超える製品を一般的にWBCSP
と言います。チップとPCBとの接続に金線を使い、マルチパッケージングが可能なことから主にメモリーチップに使います。
特に、UTCSP(Ultra Thin CSP)製品は厚み0.13㎜以下の製品を製作でき、Chip to PCB Connectionが自由なため
Multi Chip Packagingが可能で、同じ厚みのパッケージに比べて高性能を実現できます。
