W2635A + W2635A-010

W2635A + W2635A-010 is a x8, 11mm width DDR3 BGA probe adapter for x4 and x8 DRAM package. This DDR3 BGA probe adapter provides signal access to the clock, strobe, data, address, and command signals 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 the BGA package for true compliance testing. The W2635A DDR3 BGA probe adapter is soldered in between the DRAM and the PC board or DIMM raw card where the DRAM would normally be soldered. It is designed with the PCB or DIMM footprint on the bottom and the DRAM footprint on the top. The signals from the memory controller chip and DRAM are then passed directly to the top of the BGA probe adapter, where they are accessible with the oscilloscope probes. Probing is compatible with the InfiniiMax probe, which includes E2677A, N5381A, N5425A, and N5426A differential solder-in probe heads.

• Height = 13.97mm (0.550in), width = = 11.176mm (0.440in), thickness = 1.575mm (0.062in) size
• Brings 20 signals to SMT pads for probing
• Provides 12 GND pads (6 on either side of DDR3 BGA probe adapter)
• 75-ohm buried tip resistors provide signal isolation and minimize capacitive loading
