51248-4782 Datasheet, PDF (1/2 Pages) Molex Electronics Ltd. – Micro PGA Socket 478/479 Circuits For Mobile Pentium* 4 ZIF Type, BGA Mount

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 BGA-
interface 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.
