Signal Integrity

Our internal specialists understand the importance of signal integrity, and we follow strict protocols to ensure that our finalised backplanes are not prone to ringing, cross talk, ground bounce, distortion or signal loss.  With a vast amount of experience, and specialised equipment, we can design out signal integrity problems, even for high-speed backplanes.  Continue reading for an overview of our equipment and processes.

In our independent Corporate Technology Services ‘Central Laboratory’, we can also carry out environmental and other electromechanical test protocols to determine a finished backplane’s suitability for use in a range of applications, such as:

  • Climate and environmental tests.
  • Electromechanical testing: vibration and mechanical shock, material analysis and microscopic examinations, and insertion and removal forces.
  • Electromagnetic compatibility (EMC): Radiated and conducted.
