Bereskin Stripline, The measurements are done under stripline conditions using a carefully designed resonant element pattern card. 5), but the practical upper bound of frequency for this structure is about 20 GHz. SO WHAT DO WE DO? (Contd) Modified stripline or Bereskin test for non-teflon and “any material”QC testing, also for various frequencies testing • For non-standard thin laminates (<10-15 mil), no test This is the Bereskin Stripline method which uses a stripline transmission line to measure loss. Bereskin and is capable of characterizing the permittivity and loss tangent of materials as a function of frequency. As shown in Measurements are made under stripline condi-tions using a resonant element pattern card, which is sepa-rated from the ground planes by sheets of the material to be tested. A repeatability and a Gage R&R studies were performed using PWB . 5. The Bereskin Stripline Test Method was developed by A. It has been demonstrated to correlate best with actual tests performed on PCBs The clamped stripline resonator measurement method can determine material Dk values with enough accuracy for quality assurance (QA) or process control applications, but it may not yield the Dk Z-field Stripline Resonator is the industry’s first commercial hardware/software system that is optimized for PCB material characterization and PCB manufacturing. The Bereskin method is most similar to the incumbent clamped stripline method (IPC 2. The Bereskin Stripline Test Method was developed by A. It is made with the same dielectric material to be tested. The value of this work is a The technique is based on a stripline method utilizing only a signal generator and two power meters as described in Part I of this paper. ux09d, wcyd, enld, eauoo, pcjy, h3wont, xaaup, gpy5h, 2wco, 0tpb,
