Precision B2B Connectors from Ironwood
Precision B2B connectors.
Burnsville, MN — Ironwood Electronics is releasing over 100 products for its new board-to-board connector product line. The board-to-board high performance connector consists of two modules (female socket module and male pin module). Patent pending female socket module has been built with machined pins epoxy overmolded 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 — resulting in reliable connection to the PC board. 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 a match with target PC boards 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 B2B 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 4.5mm. This is the shortest connection length by far for machined pin sockets, therefore providing better transmission of high frequency signals.

These B2B connectors have passed environmental tests (MIL-STD) and qualified for various ranges of applications including automotive, military, communications, and industrial. The B2B connector line is available in many different pin counts with 1mm and 0.8mm pitch, and custom units can be delivered in days.
