Sequid GmbH - Your experts for high-frequency measurement technology
impedance control:
Sequid GmbH is a young, innovative high-tech company specializing in impedance monitoring of PCBs, connectors and cables up to the GHz range. With the high-precision DTDR-65 TDR measuring device, impedance checks can be carried out on PCBs and in systems with signal lines up to 10Gbps. Thanks to their flexibility, our systems can be used in both R&D and production environments.
Characterization of base materials (prepregs & cores):
We also offer the DTDR-65 in combination with software for determining the dielectric constants (scalar value or frequency-dependent up to the GHz range) of base materials (prepregs/cores). This allows you to reduce your manufacturing tolerances and cut production costs.
Defect detection & localization:
Since the Sequid TDR device works with very broadband signals (i.e. high spatial resolution), it can also be used for defect detection on printed circuit boards or in other electrical and electromechanical components. Sequid GmbH offers complete solutions for integration into your inspection process.
STLC - The cost-effective online tool for impedance calculation:
We offer a cost-effective online solution for calculating impedances on printed circuit boards. Using a powerful field solver method, all common cable types can be calculated online.
