1 / 2 page INTRODUCTION FEATURES AND BENEFITS 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. Micro PGA Socket 478/479 Circuits For Mobile Pentium* 4 ZIF Type, BGA Mount Applications: ■ Notebook PCs ■ Blade Servers SPECIFICATIONS Physical Housing Contact Solder Ball CAM CAM Holder Plating—Contact Area Underplating Operating Temperature Black LCP, UL 94V-0 Copper Alloy Tin/Lead, 0.76mm (.030") dia. Stainless Steel Stainless Steel Gold Nickel -20 to +90˚C Electrical Mechanical Reference Voltage Current Contact Resistance Dielectric Withstanding Voltage Insulation Resistance Durability Product Specification Packaging Designed In 100V 0.5A 25 milliohms max. AC 360V 800 Megohms min. 50 cycles PS-51248-005 Hard Tray/ Embossed Tape Millimeters LCP housing and cover with profile height of 3.30mm (.130") Stainless steel cam retainer protects plastic cover from wear. Dual-beam chamfered contact design provides low insertion force and good electrical performance. Ball Grid Array (BGA) solder balls are self-centering and avoid the problem of bent tails.
