QUALIFICATION 

QSFP_DD pc board connectors are Recognized by Underwriters Laboratories Inc. (UL) in File E28476. 

5.

 

TOOLING 

No tooling is required for manual placement of the connectors onto the pc board.  

For automatic machine placement, the robotic equipment must have a true position accuracy tolerance 
sufficient to properly locate the connector. This includes gripper and fixture tolerances as well as 
equipment repeatability. It must use the connector datum surfaces given on the customer drawing to 
ensure reliable placement.
