Dawn VME Products (Fremont, CA) has announced its newly patented Fabric Mapping Modules connector-less backplane micro-overlays to simplify and automate the optimization of backplane topologies in compliance with OpenVPX profiles. Dawn’s Fabric Mapping Modules use BGA (Ball Grid Array) substrate technology as a micro-overlay, similar in function to VME backplane overlays except FMMs can be used on VPX backplanes and are tuned for high-speed signal transmission.
