We see from your search that you're looking for information on the term "VHDM",
and we have several manufacturers' news releases and technical articles here on Electronicstalk which will be of interest.
Let me be your guide.
Begin with
the news release Backplane connector configurator goes online from
Molex UK, which we summarised at the time by saying "Molex has added the new backplane connector configurator to its website to help customers streamline the backplane connector design process".
Several months prior to that,
we featured the news release Backplane speeds differential pairs from
Molex UK: "Engineers can achieve up to 5.0Gbit/s bandwidth per signal pair with the launch of the new VHDM-HSD 6-row module-to-backplane connector system from Molex".
In June 2003, we covered the news from Teradyne
concerning its VHDM RAM connector
- take a look at Right-angle male provides backplane extension
which says: "A new eight-row right-angle male (RAM) connector has been added to the VHDM product family available from both Teradyne and Molex".
Take a look also at the news release from Teradyne, Licence adds source for high-density connectors,
as well as Website dedicated to dual-source connector family from Molex UK,
and AOI system sees all solder faults on the dark side from Teradyne.
