Kioxia and MoDeCH Develop a Three-Dimensional Probing System
High-Frequency Characteristic Measurement for Three-Dimensional Structures up to 110 GHz
Kioxia and MoDeCH developed a 3D probe station to measure high-frequency characteristics of the 3D structure (Figure 2). The station incorporates a built-in mechanism that rotates high-frequency probes and frequency extenders together, making contact with a 3D structure in order to measure it.
In addition, the companies developed thru standards for individual 3D structures (Figure 3) for accurate measurement of high-frequency characteristics. To evaluate a vertically bent 3D structure, a thru was created on a flexible substrate that was bent vertically using a jig and fixed in place to create a standard thru.
Using the developed 3D probing system and the thru standard for the 3D structure, the newly developed 3D probing system successfully measured high-frequency characteristics of two transmission lines up to 110 GHz on the two PCBs that were connected using the orthogonal connector (Figure 4).
This industry-first development is a result of the “Research and Development Project of the Enhanced Infrastructures for Post 5G Information and Communication Systems” (JPNP 20017), commissioned by the New Energy and Industrial Technology Development Organization (NEDO).
