STLC - Sequid Transmission Line Calculator

The affordable Tool for Line Impedance Calculations

Differential microstrip line with solder resist, definition window of Sequid's impedance calculatorIn addition to the TDR technology for impedance control Sequid provides an affordable PCB line impedance calculator. The STLC software applies a powerful 2-D field simulator and is capable of calculating line impedances for the most popular and mainly used transmission line types. We would be glad to inform you about prices & conditions. Do you have further questions and/or you would like to test STLC one week for free? Please call us or use our contact form to leave us a message. We are looking forward to hearing from you. 

STLC Funtionalities:

  • Calculate wave impedance
  • Coupon generator (Gerber files)
  • Loading/importing stackup files
  • Creating macro-list files for STDR-65/DTDR-65 technology
