Advantages of EMIStream

1. Reducing Iteration Process

Reduce Iteration

2. Filtering Design Errors Before EMC Engineer Evaluates Prototype PCB

EMI Filtering

EMIStream is improved with powerful features for the non EMC expert. Specifically, it indicates priority order to fix the problems in an error list and gives advice on how to control EMI problems on your PCB design.

Now EMIStream offers an EMC Expert Option for EMC professionals. It enables you to customize threshold value and in-depth parameters while also taking into account both far-field calculation and multi-layer plane structure in order to obtain a more accurate result.

Sample Effects

User Background

User Background

This user's product was a phone switchboard for a German company. Major expenses included sending several shipments from Japan to Germany to obtain certification at their test site in their local chamber.

Effect1. Cost Saving

Cost effective approach by reducing iteration processes for design/test phase and the number of components for EMI suppression.

Before Using EMIStream

Before Using EMIStream

Site test

  • Once every 3 weeks, repeat 2 or 3 times (approx. 150,000 USD)

Time of re-routing design

  • 2 to 3 weeks + Prototype creation

Costly solution by chassis, filter

  • Abt. 30 filters / 1 board (approx. 5 USD) Shipping Products: 1,000 sets × 8 boards = approx. 40,000 USD

After Using EMIStream

After Using EMIStream

Site test One time only ($50K) site repitition
Time of re-routing design Few days + Prototype creation Time saving for redesign
Costly solution by chassis, filter Reduced the number of filter reduce filters

reduce filters

Cost of the TEST site

Effect2. Time Saving for Evaluation and Countermeasures

Shorter evaluation and countermeasure time for EMI problems by reducing the time of prototype PCB creation

Effect of EMIStream #1

The figures show a comparison of before and after using EMIStream. The product is a hard disc copy device. (Actual data) The left figure shows results before using EMIStream and voltage is upper VCCI regulation at 350 MHz and 700–900 MHz. The right figure shows results after using EMIStream. From 30 MHz to 1 GHz, voltage is below VCCI regulation.

In the case of this product, the customer could reduce the cost of solution components to 1/10 after using EMIStream. Moreover, the evaluation and times for EMI suppression, which used to take ten days, now took only three.
