Backplane board with multiple gold connectors

These back panels serve as sockets for trays in server cabinets. The board shows only gold plated connectors - no bare pins. The term high grade was selected because one finds the board FULLY covered with connectors like in the category picture. In case the pins are not found to be gold plated the back plane will be put in a different category.
