HIGHLIGHTS
The Keysight W2635A and W2636A DDR3 BGA probe adapters provide 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 dynamic random access memory (DRAM) ballout, the BGA probe adapter provides direct signal access to the BGA package for true compliance testing.
The W2635A and W2636A DDR3 BGA probe adapters are soldered in between the DRAM and the PC board or DIMM raw card where the DRAM would normally be soldered. They are 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.
- The adapters provide signal access points for DDR3 DRAM x4, x8, and x16 packages using JEDEC-standard common BGA footprints to the oscilloscope.
- The 10 mm and 11 mm BGA probe adapter widths allow different spacing requirements between the DRAM placements on the PCB or DIMM.
- Buried resistors provide signal isolation and minimize capacitive loading.
- Probing is compatible with the InfiniiMax probe, which includes E2677A, N5381A, N5425A, and N5426A differential solder-in probe heads.
