BGA Interposer Advantages
The DDR5-D-CDA-78 interposer enables high speed probing at with an MA5100 series analyzer. The interposer is easy to install using standard BGA rework practices. Or take advantage of Nexus’ attachment and testing services.
Direct Attach – Convenient and Accurate
Optimal DDR5 validation requires analysis of the DDR5 signals as seen by the memory components. This allows for the highest confidence that the signals captured are representative, contain little interference, and present the maximum possible data eye size.
Attachment and Testing Services
The following services are available for this interposer.
Attachment Service
For each interposer, the Attachment Service will install a component to the interposer and the interposer to the target. Other accessories may also be attached (risers, sockets, etc.).
Target Boot & Basic Functionality
For each target, this service will power on and ensure functionality of the target with the interposer(s) installed.
MA5150: Signal Analysis & Basic Command Acquisition
This service will power on the target and place the target in a predefined state. A MA5150 analyzer will then be connected to the target and the following tests will be performed and the following reports will be provided. iCiS eye analysis report of all command, address and control signals, including recommended sampling positions and a MAx100 System Setup file.
