| INTRODUCTION Molex's latest Micro PGA sockets are designed to accept Mobile Pentium* 4 and Mobile Celeron* Processor-M series for applications such as thin notebooks and blade servers. These high-density sockets feature low profiles and proven Ball Grid Array (BGA) soldering technology for stable PCB processing. The new sockets include an easy-to-use cam mechanism and stainless steel cam retainer to prevent wear-and-tear on the housing during use. The terminal includes a dual-beam chamfered contact for good electrical performance, and BGAinterface design to ensure good thermal mismatch control between components and the PCB. Molex's Micro PGA sockets are part of our growing family of innovative socketing solutions for processor, memory and test applications. FEATURES AND BENEFITS Applications: Notebook PCs Blade Servers Micro PGA Socket 478/479 Circuits For Mobile Pentium* 4 ZIF Type, BGA Mount Blade Server *Pentium and Celeron are registered trademarks of Intel Corporation Stainless steel cam retainer protects plastic cover from wear. Blue Color Version For Centrino* Mobile Technology Processors Dual-beam chamfered contact design provides low insertion force and good electrical performance. LCP housing and cover with profile height of 3.30mm (.130") Accepts energy-saving Pentium mobile processors For notebooks, blade servers and small desktop PCs 478 circuits Small pin layout difference and blue color to differentiate from standard P4-M socket Same features as standard P4-M socket Order No.: 500210-4784 * Centrino is a trademark of Intel Corporation Ball Grid Array (BGA) solder balls are self-centering and avoid the problem of bent tails.
