STLC – Sequid Transmission Line Calculator

At Sequid, we specialize in high-quality solutions for impedance control. In addition to our advanced TDR technology, we offer the STLC software, an affordable yet powerful PCB line impedance calculator. Using a state-of-the-art 2D field simulator, STLC accurately computes line impedances for the most commonly used transmission line types, ensuring precise and reliable results for your PCB designs.

STLC simplifies your workflow by seamlessly supporting layer stackup imports and effortlessly generating impedance test coupons with just a few clicks.

When combined with our advanced TDR software SeunisPro, you can effortlessly export Measurement Sequence Files, enabling streamlined and highly efficient measurement processes.
