More details

More info

These back panels serve as sockets for trays in server cabinets. They carry either connectors or bare gold plated pins. The term grade E was selected because one finds less 50% of the board covered with connectors or pins. In case the pins are not found to be gold plated the back plane will be put in a different category.
