HFTAP Series

The industry-leading performance of the HFTAP K32 product joins FormFactor’s series of High Frequency Test probe cards, including the K10, K16 and K22 used for testing 1.0 GHz, 1.6 GHz, and 2.2 GHz DRAM devices. Advanced PCB technology, exclusively available from FormFactor, allows the fastest communication between the Device Under Test (DUT) and Automated Test Equipment (ATE). By utilizing FormFactor’s Matrix architecture, HFTAP K32 probe cards can test at speeds that no other full wafer contactor can achieve.

The extended capability of FormFactor’s HFTAP K32 probe card architecture enables DRAM customers on wafer-level speed testing up to 3.2 GHz/ 6.4 Gbps for next generation known-good-die (KGD) memory. The recent industry-wide adoption of heterogeneous integrated systems enabled by 2.5D and 3D advanced packaging technology is driving the demand for KGD. The benefit of KGD testing ensures the final stacked and assembled package does not get scrapped due to one bad chip.

This advanced MEMS probe card architecture is used to verify electrical performance and yield, not only for the individual chips, but also devices used in the HBM stack, including the fine-pitch interposer to ensure the performance of the complete package. The HFTAP K32 probe card solution empowers customers to gain more intelligence at any stage of the heterogeneous integration process for advanced packages, where the traditional way to optimize yield on a monolithic silicon die is no longer adequate. HFTAP probe card solutions are available at lower speeds based on device requirements.
