XZIF Presentation

The Double Sided-High Density (DS-HD) XZIF interconnect is the second generation of XZIF development by Xandex. The DS-HD XZIF is designed to increase contact density and improve performance at a reduced cost per contact.

Compared to the first generation XZIF interconnect, the DS-HD electrical path is capable of significantly higher bandwidth and electrical performance, with double the contact durability.

The modular XZIF interconnect is customizable to fit most test requirements. It is the optimal solution for volatile or non-volatile Memory test applications, SOC test applications and is ideal for dymanic high current delivery to the DUT.

And, by changing the direction of contact force from vertical (spring probe) to horizontal (clamp), the XZIF interconnect reduces compression force on the DUT test board by nearly 90%!

The XZIF DS-HD DUT Interconnect Cycle

1) The DUT connector approaches the clamp assembly. Guides on the clamp assist alignment.  2) The DUT connector engages the clamp and is aligned to shafts in the clamp assembly. 3) The DUT connector is fully engaged in the clamp and compressed slightly in the clamp to ensure perfect alignment. 4) The clamp pneumatic cylinder is actuated, compressing the two sides of the clamp against the DUT connector with high force.

 

Narrow XZIF Double Sided-High Density Interconnect (XZIF DS-HDn)

DHigh Density Xandex Zero Insertion Force Interconnect (XZIF) with Narrow Form Factor for High Density Memory Test Applications

The Narrow form factor Double Sided-High Density (DS-HD) XZIF interconnect is the second generation of XZIF development by Xandex for Memory Test. The DS-HDn XZIF interconnect is designed to increase contact density and improve performance at a reduced cost per contact.

Compared to the first generation XZIF flex interconnect, the DS-HDn XZIF utilizes interposer technology for higher channel density and superior DC contact resistance.

The modular XZIF interconnect is customizable to fit most test requirements. It is the optimal solution for volatile or non-volatile Memory test applications. The narrow form factor clamp is especially useful for smaller probe cards (300 + mm) or larger probe cards (440 + mm) with a large keep out area.

And, by changing the direction of contact force from vertical (spring probe) to horizontal (clamp), the XZIF interconnect reduces compression force on the DUT test board by nearly 90%!
