Chip Size BGA 0.8mm Board-to-Board Connector

Users can connect their 676 pin 0.8mm pitch BGA footprint on mother board to the same footprint on upgraded daughter board using Board-to-Board connector with excellent signal integrity

BURNSVILLE, MN - July, 2009 - Ironwood Electronics' releases over 100 products for its new board-to-board connector product line. Board-to-board high performance connector consists of two modules (female socket module and male pin module). Patent pending female socket module was built with machined pins epoxy over molded into an assembly that matches the male pin module with similar construction. The RoHS compliant SF-BGA676D-B-62F (female socket module) can be soldered to a mother board using standard RoHS soldering methods without warping that result in reliable connection to PCB. Similarly, SF-BGA676D-B-61F (male pin module) can be soldered to an upgraded daughter board. Both modules are constructed with high temperature FR-4 substrate assuring match with target PCB's and preventing failures that occur with CTE mismatch. SF-BGA676D-B-61F is plugged into SF-BGA676D-B-62F on the board, thereby daughter and mother boards are interconnected and the system is ready to go. The modules come with both lead and lead free solder ball types. The board-to-board connector pair requires half the force of conventional connectors at 20 pounds for the 676 pin interface for ease of operation. The electrical path of the Board-to-Board connector is a high priority performance issue with the physical length from the top connection point on the male pin module to the solder ball on the female socket is 4.5 mm. This is the shortest connection length by far for machined pin sockets, therefore providing better transmission of high frequency signals. These Board-to-Board connectors passed environmental tests (MIL-STD) and qualified for various range of applications including automotive, military, communications, industrial, etc. The Board-to-Board connector line is available in many different pin counts with 1mm & 0.8mm pitch, and customs can be delivered in days.

Pricing for the SF-BGA676D-B-62F @qty1 = $404.00 each and SF-BGA676D-B-61F @qty1 = $184.00
