IRONWOOD ELECTRONICS Board-to-board socket adapter, for 352 pin BGA, 1mm pitch, 27x27mm IC size, 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. SF-BGA352B-B-42 (female socket module) can be soldered to a mother board using standard soldering methods without warping that result in reliable connection to pcb. SF-BGA352B-B-41 (male pin module) can be soldered to an upgraded daughter board. Both modules are constructed with high temperature FR-4 substrate.
