The Keysight W2636A DDR3 ball grid array (BGA) probe adapters provide signal access to the clock, strobe, data, address, and command signals for making electrical and timing measurements with a Keysight Infiniium oscilloscope. Compliant with the DDR3 JEDEC specification (JESD79-3A) for dynamic random-access memory (DRAM), the BGA probe adapter offers direct signal access to the BGA package, ensuring accurate compliance testing.

The Keysight W2636A and W2635A DDR3 BGA probe adapters are soldered between the dynamic random-access memory (DRAM) and the PC board or dual in-line memory module (DIMM) raw card. The printed circuit board (PCB) or DIMM footprint is located at the bottom, and the DRAM footprint is positioned at the top. The memory controller chip and DRAM signals pass directly to the top of the BGA probe adapter, where they are accessible with the oscilloscope probes.

The probe adapters can help you with the following:

  • The adapters provide signal access points for DDR3 DRAM x4, x8, and x16 packages using JEDEC-standard common BGA footprints to the oscilloscope.
  • Enable various spacing requirements between the DRAM placements on the PCB or DIMM with 10 mm and 11 mm BGA probe adapter widths.
  • Minimize capacitive load with buried resistors that isolate the signal.
  • Ensure compatibility with the Keysight InfiniiMax probe, which includes Keysight E2677A, N5381A, N5425A, and N5426A differential solder-in probe heads.
  • Download the Keysight Digital BGA Interposer catalog for LPDDR2 / 3 / 4 BGA interposer information.
