Analysis (3D Analysis)


Leading in the field of high-frequency and high-speed transmissions, I-PEX provides excellent signal integrity solutions with the development of a wide variety of ultra-precision connectors.
In the development process, I-PEX utilizes 3D electromagnetic field simulators, such as CST STUDIO and HFSS, to verify compatibility with millimeter-wave and ultra-high-speed transmission and provides various simulation data at the customer’s request.

SI simulation


  • 3D Electromagnetic Field Simulation

The high frequency response data in connector structure is provided as a high-precision 3D full model. In addition, the electromagnetic field distribution propagating in space is observed to verify the shielding performance of connectors, and near-field and far-field EMC measurements are verified at the product design stage.

  • CST STUDIO (Dassault Systèmes Inc.)
  • HFSS (ANSYS Inc.)

 

Analysis of the entire PCB, including net and component information, is possible by importing the CAD data of the PCB, and the characteristics of the connector mounted condition can be reproduced.

  • PCB CAD Tools:
    • OrCAD (INNOTECH Corp.)
      ・PCB design
      ・Development of PCB CAD data into analysis models
       
    • SIwave (ANSYS Inc.)
      ADS (Keysight Technologies, Inc.)
      ・2.5D electromagnetic field, Signal Integrity, Power Integrity 
      ・Data formats such as IBIS-AMI and touchstone can be imported
       
  • 2D, 2.5D Electromagnetic Field Analysis

Examples of connector and PCB layouts are proposed to comply with transmission standards.
The pattern layouts around the connectors that are suitable for the transmission standard and the layer configuration of the PCB are verified, based on the effects of reflections and crosstalk noise from mounted components and signal traces.
In addition, the impedance and electric field strength distribution from the power supply to the ground are analyzed by incorporating the layout of the entire PCB and the identification and improvement of power supply noise are verified.
