BGA probe adapter for Infiniium Oscillscopes
The Keysight Technologies W2635A and W2636A DDR3 BGA probe adapters provide signal access to the clock strobe data address and command signals to the DDR3 BGA package for making electrical and timing measurements with an Infiniium oscilloscope. With the DDR3 JEDEC specification (JESD79-3A) defined at the DRAM ballout the BGA probe adapter provides direct signal access to BGA package for true compliance testing. The W2635A and W2636A DDR3 BGA probe adapters are soldered in between the DRAM and PC board or DIMM raw card where the DRAM would normally be soldered. They are designed with the PCB or DIMM foot print on the bottom side and the DRAM footprint on the top side. The signals from the memory controller chip and DRAM are then passed directly to the top side of the BGA probe adapter where they can be accessed with the oscilloscope probes.
