Merit of EMIStream

1. Reducing Iteration Process

Reduce Iteration


2. Filtering Design Errors Before EMC Engineer Evaluates Prototype PCB

EMI Filtering

EMIStream V4 is improved with powerful features for non EMC expert. It indicates priority order to fix the problems in error list and gives advice how to control EMI problems on your PCB design.
Now EMIStream V4 produced EMC Expert Option for EMC professionals. It does not only enable you to customize threshold value and in-depth parameters, but also take into account both far-field calculation and multi-layer plane structure in order to obtain more accurate result.


Sample Effects

User Background

User Background

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

Effect1. Cost Saving

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

Before Using EMIStream

Before Using EMIStream

Site test
Once in 3wks, repeat 2 or 3 times (aprox.$150,000)
Time of re-routing design
2 to 3 wks+ Prototype creation
Costly solution by chassis, filter
Abt. 30 filters/ One board (Aprox.$5)
Shipping Products: 1,000 sets x 8 boards = aprox. $40,000

After Using EMIStream

After Using EMIStream

Site test

Time of re-routing design

Costly solution by chassis, filter

One time only ($50K)

Few days + Prototype creation

Reduced the number of filter

site repitition Time saving for redesign 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 are a before and after comparison 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 350MHz and 700-900MHz. The right figure shows results after using EMIStream. From 30MHz to 1 GHz, voltage is below VCCI regulation.

In this product case, the customer could reduce solution components costs to 1/10 after using EMIStream. Evaluation and times for EMI suppression which used to take 10 days, now only takes 3 days after using EMIStream.
