Original Press Release:

Mobile Pentium* 4 Processor-M Socket from Molex Offers High-Density BGA Packaging

Achieve high-density Ball Grid Array packaging for the Intel* Mobile Pentium 4 Processor-M series with the new Micro PGA socket from Molex Incorporated. This socket is available in 478 circuits and can also be used with Intel Mobile Celeron* processors for applications such as blade servers or thin notebook PCs.

The socket's BGA solder balls are self-centering and help to prevent bent leads that can occur with standard SMT tails, especially in high pin count applications. BGA processing also provides good thermal control between components and the PCB for stable reflow soldering.

Molex's new Micro PGA socket has a profile height of only 3.30mm
(.130"), which is ideal for thin notebook PCs and servers. The socket is based on a 1.27mm (.050") grid array and accepts a PCB interposer that has the processor package mounted to it.

The interposer's Micro PGA pins are inserted into the Molex socket and a ZIF (Zero Insertion Force) actuation cover engages the contacts by simply turning a CAM mechanism with a standard screwdriver. The CAM mechanism includes a stainless steel retainer that protects the housing from wear.

Other features of the new socket include a dual-beam chamfered contact design that provides low insertion force and reliable electrical performance. The LCP housing and cover can withstand high-temperature soldering environments, while gold-plated terminals provide smooth engagement and secure electrical contact. This new socket is rated at 0.5A and 100V. It can be ordered in tray or tape-and-reel packaging, with a vacuum cover for automated placement.

Pricing for this product depends on quantity. For example, when
purchased in quantities of 25,000, this Micro PGA socket cost $10.40 each. Typical lead time is six to eight weeks.
